Description
Stainless Steel Grade 410/1.4006 is a martensitic stainless steel with high strength and hardness properties. It is magnetic in both annealed and hardened conditions. Grade 410/1.4006 offers good corrosion resistance to mild atmospheres, steam, and mild chemical environments. This steel grade is primarily used where high mechanical properties are required and can be hardened and tempered to achieve a wide range of hardness and mechanical properties.

Fabrication and Heat Treatment
Forming: Grade 410 can be easily formed using standard methods. However, forming should be done in the annealed condition.
Welding: Can be welded using all standard methods, but pre-heating and post-weld heat treatment are recommended to reduce the risk of cracking.
Machining: This grade exhibits good machinability in the annealed or normalized condition but is more challenging to machine when hardened.
