Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 904L Washers, which is similar to Alloy 904, but has more strength and hardness. Stainless Steel 904L Flat Washers can be hardened through heat treatment, which brings good ductility for metal fabricators as well as excellent polishability. Application of SS 904L Lock Washer could result in real cost savings when carefully compared to higher – cost alloys to determine if the necessary resistance is obtained in the chosen media. Stainless Steel 904L Sealing Washer has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulphuric, phosphoric, and nitric acids.

SS 904L Split Washers also contains niobium for stabilization against sensitization and resultants inter – granular corrosion, where this transformation is not complete until the temperature drops to 90 Degree F. Restricted carbon plus columbium stabilization of Stainless Steel 904L Slot Washers permits welded fabrications to be used in corrosive environments, normally without post – weld heat treatment.
SS 904L Machine Washers appears to fall between both the stainless and nickel categories as it contains characteristics of both. We supply Stainless Steel 904L Star Washer for a variety of applications and will help in determining the precise amount for your current project. Although SS 904L Spring Washers was designed for use in sulphuric acid related industries; it finds wide usage throughout the chemical processing industry.
