Can Wear-Resistant Steel Plate Be Used in the Aerospace Industry?

When I first started working as a wear-resistant steel plate supplier back in 2012, I’ll admit, my focus was almost entirely on industries where abrasion and impact were non-negotiable—mining equipment, cement mills, agricultural machinery, the kind of places where steel parts literally wear down from constant contact with rocks, grain, or harsh chemicals. So when a aerospace engineer reached out to me two years ago, asking if our wear-resistant plates could work for a new landing gear component, I had to pause. Aerospace? That’s a world I’d only read about in trade magazines, where every part has to balance extreme strength with feather-light weight, where failure isn’t an option, and where materials are vetted for years before they ever touch a real aircraft.

But that question stuck with me. For months, I dug into the data, talked to metallurgists I partner with, and followed case studies from aerospace research centers. Today, I’m here to share what I’ve learned—because if you’re in either the wear steel business or the aerospace field, the overlap between these two worlds is bigger than you might think. Spoiler: the short answer is yes, but not the kind of wear-resistant plate you’d find in a mining truck bucket. It’s a niche, specialized subset of wear-resistant steel, designed to check boxes that most abrasion-resistant grades never even consider.

Let’s start with the basics. What makes a steel plate “wear-resistant” in the first place? Most standard wear grades, like AR400 or AR500, get their toughness from high carbon content and alloying elements like chromium, molybdenum, or nickel, combined with a heat treatment that creates a hard surface layer. That’s perfect for a bulldozer blade that’s scraping against rock all day, but aerospace parts don’t just need hardness—they need to survive temperatures that swing from -60°F at 30,000 feet to over 500°F during takeoff, resist corrosion from jet fuel and hydraulic fluids, and have a strength-to-weight ratio that’s unheard of in heavy equipment. If our standard AR500 plate weighed twice as much as a traditional aerospace steel for the same strength, it would never fly—literally.

So when that aerospace engineer called, he wasn’t looking for a plate that could outlast a mine. He was looking for a wear-resistant steel plate that met AMS (Aerospace Material Specifications) standards, which are some of the strictest in the manufacturing world. AMS specs dictate everything from chemical composition to fatigue resistance to how a material performs under extreme cyclic stress—something that’s critical for parts that go through thousands of takeoff and landing cycles over decades.

Let me give you an example of where this is already working. A few months ago, I helped a team working on small business jets with custom wear plates for the cargo bay floor. If you’ve ever seen how luggage gets loaded onto a plane—heavy metal carts rolling back and forth, sharp-edged cargo being dragged in and out—you know that cargo bay floors take a beating. Traditional aluminum alloy floors would scratch and dent within a few years, leading to maintenance delays and replacement costs. The team tried two options: standard stainless steel, which is heavy and prone to seizing, and our specialized wear-resistant steel that’s been modified for aerospace use.

What makes this grade different from our industrial wear plates? First, we reduced the carbon content slightly, which cuts weight but keeps the surface hardness high enough to resist abrasion from cargo and carts. Then we added a small amount of vanadium, which strengthens the grain structure of the steel without adding extra pounds. Most importantly, we did a secondary heat treatment called cryogenic tempering, which eliminates internal stresses in the steel—something that’s a must for aerospace parts that will be exposed to thousands of thermal cycles. The result was a plate that’s 30% lighter than our standard AR400 wear plate, has comparable abrasion resistance, and meets AMS 4411, the spec for structural steel in aircraft frames and components.

Of course, it’s not all smooth sailing. There are big challenges that keep most wear-resistant steel out of the aerospace industry. The first is certification. Aerospace parts require rigorous testing—salt spray corrosion tests that last 1,000 hours, fatigue tests that simulate 20 years of use in weeks, and crashworthiness tests that make sure the material doesn’t shatter on impact. Most industrial wear plates are never tested to these standards, and getting a grade certified for aerospace is a years-long process that costs millions of dollars in R&D and testing. As a supplier, we don’t just sell a plate—we have to provide traceability for every batch, every heat treatment run, every chemical test result. That’s a level of documentation that’s way beyond what we do for mining clients, who just need a certificate of conformance.

Another challenge is cost. Aerospace-grade wear-resistant steel is significantly more expensive than both industrial wear plates and traditional aerospace steels like 7075 aluminum or 4130 chromoly. Why? Because the production process is more controlled. We have to use higher-quality raw materials, with fewer impurities that could cause cracks or corrosion in critical aerospace parts, and every step of manufacturing is monitored with precision equipment. For most commercial aircraft, the cost difference isn’t justified for cargo bay floors or landing gear brackets, but for smaller, specialized aircraft like military transports or business jets, where durability and maintenance costs matter more than raw material price, it’s a no-brainer.

I also talked to a metallurgist at a NASA contractor last year, who mentioned that wear-resistant steel is even being considered for parts of rocket engines. Rocket engines deal with extreme temperatures and rapid cycling—when a rocket launches, temperatures can spike to over 3,000°F in the combustion chamber, and then drop back to ambient once it’s in space. The valves that control fuel flow have to resist both thermal fatigue and abrasion from high-speed fuel particles. Traditional nickel-based superalloys are strong enough, but they’re prone to wear. Our modified wear-resistant steel, with its high temperature stability and hard surface layer, could be a game-changer there—though it’s still in testing phase.

So what does this mean for suppliers like me? A few years ago, we never would have considered catering to aerospace clients. Today, we have a dedicated team that works with AMS specs, a testing lab on-site that can perform fatigue and corrosion tests, and partnerships with aerospace engineering firms that help us refine our wear-resistant plates to meet their exact needs. It’s been a steep learning curve, but it’s also been rewarding—knowing that a material we originally made to keep mining equipment running longer is now helping aircraft stay safe and in the air.

Let me also address a common misconception: some people think that using wear-resistant steel in aerospace is overkill, that aluminum or titanium is enough. But if you’ve ever waited for a flight because the maintenance crew had to replace a scratched cargo floor, you know that overkill isn’t just about durability—it’s about reliability and cost. A single hour of aircraft downtime can cost thousands of dollars in lost revenue, so a slightly more expensive material that reduces maintenance and extends part life pays for itself in no time.

Right now, the biggest growth area for wear-resistant steel in aerospace is in aftermarket parts. Many airlines are retrofitting their older fleets with wear-resistant cargo bay floors, stair treads, and landing gear components to reduce maintenance. That’s where we come in—supplying custom-cut plates that fit exactly into existing aircraft, with the certifications and traceability that airlines require. We’re not making entire aircraft structures with our steel yet, but we’re making the parts that keep those structures running smoothly.

If you’re reading this and you’re an aerospace engineer or maintenance manager, I’d encourage you to look into specialized wear-resistant steel grades for your next project. The key is to work with a supplier who understands both wear technology and aerospace standards—someone who can walk you through the testing, the certifications, and the trade-offs between weight, strength, and durability. And if you’re a wear steel supplier like I was five years ago, don’t write off aerospace too quickly. The overlap between our industries is real, and it’s only going to grow as aircraft manufacturers look for more efficient, longer-lasting materials.

At the end of the day, materials science is all about adapting a proven technology to new needs. We’ve been making wear-resistant steel for decades to handle the harshest industrial environments, and now we’re just fine-tuning that technology to meet the equally harsh demands of the sky. It’s a reminder that the best materials often cross industry lines—you don’t have to reinvent the wheel to solve a new problem, you just have to look at what you already make with a fresh perspective.
