410 Stainless Steel

420 is martensitic stainless steel that provides good corrosion resistance similar to 410 plus increased strength and hardness.

410 stainless steel

410 stainless steel is suitable for applications where high strength and moderate heat and corrosion resistance are required.

Type 410 is a martensitic alloy commonly supplied in the hardened but still machinable condition. Type 410 has excellent hardness after heat treatment and the material can be used in the fabrication of highly stressed parts.

Applications include valves, gar turbines, parts for pumps, heating control shafts, and kitchen utensils. We supply 410 in sheets, strips, bar, wire, and forging billets, contact us today for the best prices.
