About Stainless Steel 321 Fasteners

Nissan Steel is a renowned manufacturing company in Mumbai, India, that manufactures, sells, and exports high-quality Stainless Steel 321 Fasteners. These Stainless Steel 321H fasteners are manufactured using cutting-edge technology and excellent raw materials. Stainless Steel 321 Fasteners are austenitic stainless steel treated with titanium, making it more corrosion-resistant. After being heated to between 800 and 1500 degrees Fahrenheit (427 and 816 degrees Celsius), chromium carbide transforms into a solid highly resistant to corrosion between grains.

SS 321H Fasteners comprise an alloy containing between 0.04% and 0.10% carbon. The alloy is oxidation-resistant at temperatures up to 1500 degrees Fahrenheit (816 degrees Celsius) and has superior ruptured creep and stress properties than alloys 304 and 304L. This also has good low-temperature tolerance. It was designed to resist bending and be more durable at temperatures above 1000 degrees Fahrenheit (537 degrees C). SS 321 fasteners can only be hardened while in the cold. Using typical welding procedures, it is simple to weld and manipulate in production. Most diluted organic acids can be utilised with SS 321 Fasteners at mild temperatures. Pure phosphoric acid and up to 10% diluted solutions can be employed at low and high temperatures. Alloy 321 is resistant to polythionic acid-induced stress corrosion cracking in hydrocarbon service. They work in moderately hot caustic solutions without chloride or fluoride. 321 SS Fasteners, even in modest concentrations, don’t operate well in chloride or sulphuric acid solutions.

Stainless Steel 1.4541, 1.4878 Fasteners can be utilised for various applications, including aircraft piston engine manifolds and exhaust stacks, expansion joints, thermal oxidisers, refining equipment, high-temperature chemical processes equipment, food production and storage equipment, etc. Our Stainless Steel 321H Fasteners are available in various sizes, specifications, widths, grade materials, and dimensions and can be customised to meet the needs of each client.
