Washers that are made up of stainless steel are utilized for the purpose of closing and sealing the connections between two elements or fasteners. The addition of nickel content in Stainless Steel 304 Washers enhances its ability of resistance towards corrosion. Cold working process is done so that the tensile strength of 304L Stainless Steel Washers is improved. Austenitic 304H Stainless Steel Washers are also the most weldable of the high-alloy steels.
Stainless Steel 310S / 310H Washers have characteristics such as ductility. Molybdenum elements provide greater resistance to pitting and crevice corrosion in chloride situations, increasing the value of these Stainless Steel 316 / 316H / 316L Fasteners in industries. The Stainless Steel 317 / 317L Washers also have characteristics such as durability and long service life.
Stainless Steel 321/321H Fasteners also have characteristics and properties such as tensile strength. The Stainless Steel 347/347H Washers have properties such as high performance along with resistance towards corrosion. The Stainless Steel 409 Washers are resistant towards heat as well as corrosion. The Stainless Steel 410s Washers are fasteners that are also used in a wide range of applications because of their properties.
