Harshita Stainless produces SS 405 Nuts with high dimensional accuracy and precise threads, guaranteeing dependable and safe assemblies. The company, which serves both domestic and international markets, is dedicated to quality, timely delivery, and customer satisfaction. Its industries include manufacturing, petrochemical, automotive, and power.
The ferritic stainless steel fasteners known as Stainless Steel 405 Nuts are mainly made of chromium (11.5–14.5%) and have a low carbon content. Aluminium is added in trace amounts to increase oxidation resistance. These nuts have good machinability and a moderate resistance to corrosion. SS 405’s mechanical properties include a tensile strength of about 415 MPa, a yield strength of about 205 MPa, and an elongation of about 20%. The alloy exhibits good scaling resistance and performs well at high temperatures. Applications needing moderate structural strength and high heat resistance in oxidising environments can benefit from the magnetic properties of stainless steel 405 as well.
