Stainless Steel Bolts

Stainless Steel Bolts 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 Bolts 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 Bolts supplier in India.

Austenitic Stainless Steel Bolts

Stainless Steel Bolts 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 Bolts range from 75000 to 105000 psi in as rolled condition.

Martensitic Stainless Steel Bolts

Heat treated fasteners with martensite grain structure is the specialty of martensitic Bolts. With chromium content of 12%-18%, these stainless steels have poor welding characteristics with magnetics nature. Since this steel can be hardened by heat treatment tensile strength of 70000 to 145000 psi can be achieved.
Below is the list of most common martensitic stainless steel grades.

Ferritic Stainless Steel Bolts

Ferrite grain structure is the specialty of Ferritic bolts With chromium content of 12%-18%, these stainless steels have carbon content lesser than 0.2% enhancing poor welding characteristics with magnetics nature. Below is the list of most common Ferritic stainless steel grades.

Precipitation Hardening Stainless Steel Bolts

Stainless Steel Bolts Most familiar by the name iron-nickel alloys containing more than one precipitation hardening elements like titanium, aluminium, copper, niobium, and molybdenum. This stainless steel have high mechanical properties including the tensile strength and higher corrosion resistance.

Precipitation hardening steels are further divided into three different types.
