Ninthore Overseas is one of the Leading Manufacturer And Exporter of high quality Stainless Steel 310H Washers, which is an authenticate stainless steel developed for use in high temperature corrosion resistant applications. SS 310H Flat Washers resists oxidation up to 2010 Degree F (1100 Degree C) under mildly cyclic conditions. Because of its high chromium and moderate nickel content, SS 310H Lock Washers is resistant to suffixation and can also be used in moderately carburizing atmospheres. The more severe carburizing atmospheres of thermal process equipment usually require nickel alloys such as SS 310H Sealing Washers.

When heated between 1202 Degree F – 1742 Degree F (650 Degree C – 950 Degree C), Stainless Steel 310H Split Washers is subject to sigma phase precipitation. Stainless Steel 310H Slot Washers can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced. Stainless Steel 310H Machine Washers also finds usage in cryogenic applications with low magnetic permeability and toughness down to -450 Degree F (-268 Degree C).

A solution annealing treatment of SS 310H Star Washers at 2012 Degree F – 2102 Degree F (1100 Degree C – 1150 Degree C) will restore a degree of toughness. Due to high resistivity and strength these Stainless Steel 310H Spring Washers are highly useful in various industries and applications like Chemical processing plants, automobile, mechanical parts factories are the firms that insist for such fittings on a daily basis.
