Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Alloy 218 Washers, which is best known for its wear and galling resistance. Higher strengths of these Alloy 218 Flat Washers are attainable in the course of cold working the material and is still fully austenitic after severe cold – working. Our Alloy 218 Lock Washers is one of the best – selling known for its durable leak – proof property. The additions of Si and Mn have given these Alloy 218 Sealing Washers a matrix to inhibit wear, galling, and fretting even in the annealed condition.

Our Alloy 218 Split Washers is often chosen to solve SCC problems, which may perhaps occur with 316L stainless. These Alloy 218 Slot Washers was designed for maximum resistance to acid attack and demonstrates superior resistance to stress – corrosion cracking in boiling 20 % sulfuric acid to 40 % sulfuric acid. Our Alloy 218 Machine Washers as well has excellent general corrosion resistance to sulfuric acid and to chloride stress corrosion cracking.
These Alloy 218 Star Washers has good mechanical properties at both ambient and elevated temperatures, up to approximately 930 Degree F (500 Degree C) and is readily fabricated by usual industrial processes. Our Alloy 218 Wire Spring Washers combines excellent corrosion resistance with elevated mechanical properties and relatively easy fabrication. These Alloy 218 Flat Spring Washers is composed of carbon, chromium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, and sulfur.
