Sachiya Steel International is one of the prominent dealer and stockiest of Stainless Steel 410 Washers, which cannot be hardened by heat treatment. The austenitic SS 410 Flat Washers are considered to be the most weldable of the high – alloy steels and can be welded by all fusion and resistance welding processes.

SS 410 Lock Washers is annealed in the 1600 Degree F – 1650 Degree F (871 Degree C – 899 Degree C) range and then air cooled to relieve cold working stresses. Stainless Steel 410 Sealing Washer should not be exposed to temperatures of 2000 Degree F (1093 Degree C) or above due to embrittlement.

If excessive large grains are encountered after annealing mildly cold – worked material, the annealing temperature of SS 410 Split Washers should be decreased to a range of 1200 Degree F – 1350 Degree F (649 Degree C – 732 Degree C) range. For maximum corrosion resistance to chemical environments, it is essential that the surface of Stainless Steel 410 Slot Washer be free of all heat tint or oxide formed during annealing or hot working.

All surfaces of Stainless Steel 410 Machine Washers must be ground or polished to remove any traces of oxide and surface decarburization. The parts of SS 410 Star Washers should then be immersed in a warm solution of 10 % – 20 % nitric acid followed by a water rinse to remove any residual iron.
