The Workhorse Martensitic That Earns Its Keep
We’ve seen countless stainless grades come and go, but 410 keeps showing up where it matters – in applications that demand more than just rust resistance. It’s that reliable workhorse in our warehouse that gets specified for everything from surgical trocars to turbine shafts, often because engineers know they need the right balance of hardenability and corrosion resistance without breaking the bank.
What makes 410 special is how it performs when properly heat treated. The 12.5% chromium gives decent oxidation resistance, but the magic happens when you quench and temper. We typically see hardness jump to 40-45 HRC with proper treatment, making it perfect for applications where wear resistance matters. One of our automotive clients uses it for transmission shafts that undergo induction hardening – they get the core toughness they need while achieving surface hardness up to 55 HRC.
Where Performance Meets Practicality
The real advantage? 410 gives you options.
– Machined in the annealed condition (around 180-200 BHN), it behaves like carbon steel but with better corrosion resistance
– When hardened, it outperforms 304 in wear applications while costing 20-30% less
– Welding is doable but requires care – we always recommend preheating to 300-400°F and post-weld stress relieving
We’ve had medical device clients specify 410 for trocars that need to hold a razor edge after sterilization cycles. The key is the consistent grain structure we maintain through our controlled rolling and annealing process. For architectural applications, the 2B finish holds up well in coastal environments – just not as a primary structure where chloride exposure is constant.
Made for Your Exact Needs
Thickness ranges from thin 0.3mm sheets for precision components up to 50mm plates for heavy machinery bases. Our ISO 9001-certified process keeps thickness tolerance tight (±0.02mm) even on custom widths up to 2500mm.
Being a China-based mill, we control quality from melt to finish. Need special edge conditions for laser cutting? We’ve got you covered. Want to combine 410 with 304 in a bi-metal application? We’ve done that too. Our technical team can help optimize the heat treatment parameters for your specific application.
If you’re working on something that needs stainless performance but can’t afford exotic alloys, let’s talk. We’ll send samples, share real-world case studies, and work with your specs – not force you into standard dimensions.
