Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 310 Washers, which results in less internal stress and, most important, a deeper hardened zone in the work – piece. Alloying elements have a strong influence on heat-treating; because SS 310 Flat Washers tend to slow the diffusion of atoms through the iron lattices and thereby delays the allotropic transformations. This means, for example, that the extremely hard martensite of Stainless Steel 310S Lock Washers, which is normally produced by fast quenching, can be produced at lower cooling rates.

Improved hardenability of Stainless Steel 310 Sealing Washers is achieved by adding such elements as manganese, molybdenum, chromium, nickel, and boron. These alloying agents in SS 310S Split Washers also permit tempering at higher temperatures, which generates better ductility at the same hardness and strength. The testing of properties in Stainless Steel 310 Slot Washers often begins with checking hardness.
Stainless Steel 310S Machine Washers is measured by pressing a diamond pyramid or a hard steel ball into the steel at a specific load. Tensile and yield strength of SS 310 Star Washers are determined by pulling a standardized machined sample in a special hydraulic press and recording the pulling force at increasing elongations until the sample breaks. The elongation of SS 310S Spring Washers, and the way the fracture looks, is good indications of the steel’s ductility.
