Stainless Steel Fasteners

Stainless Steel Fasteners is basically an iron-based alloy with minimum 10.5% chromium content. The word Stainless is derived from its oxidation resistance properties thus making the steel passive to corrosion often known by the technical term corrosion resistance.

Stainless Steel Fasteners with Addition of other elements such as nickel, molybdenum and is a general practice to induce other important properties like corrosion resistance at higher temperatures thereby introducing heat resistance.Torqbolt is a well known Stainless Steel Fasteners supplier in India.

Austenitic Stainless Steel Fasteners

Stainless Steel Fasteners with higher amounts of chromium and nickel as compared to other grades are referred as austenitic stainless steel. This steel is generally non-magnetic in nature. Austenitic steels have high corrosion resistance and cannot be hardened by heat treatment. The tensile strength of these Stainless Steel Fasteners range from 75000 to 105000 psi in as rolled condition.

Strain Hardened Austenitic Stainless Steel Fasteners

Strain Hardening is done to achieve high tensile values ranging from 600 Mpa "“ 1100 Mpa depending on the Stainless steel Grades.

Below is the list of Strain Hardened Stainless Steel Grades as per ASTM Specifications referred as class 2.

Austenitic Stainless Steel Fasteners for low temperature service

Controlled chemistry of elements like carbon, sulphur and phosphorous are implemented to increase stainless steel sustainability at cryogenic temperatures which is at a very low temperature ranging from zero degrees to -80 degrees.

This results in high Toughness and impact resistance, which is a very important part of cryogenic applications.

Below is a list of all the Stainless Steel Fasteners used at lower temperatures Included equivalent designations of all L grades and A320 Fasteners.
