A reputable producer and supplier of stainless steel 416 tubing, Harshita Stainless is situated in Delhi, India, and is well-known for its exceptional machinability and resistance to corrosion in mild conditions. SS 416 tubing, a martensitic stainless steel that offers improved mechanical properties through heat treatment, is specifically designed for applications needing strength and accuracy. Harshita Stainless offers tubing solutions that satisfy both client-specific needs and global quality standards. The company serves a variety of industries, including engineering, automotive, defence, and instrumentation, both in India and international markets, with an emphasis on consistent quality, dimensional accuracy, and timely delivery.
Chromium (12–14%), iron as the base, and sulphur (up to 0.15%) to enhance machinability make up stainless steel 416 tubing. Carbon, silicon, and manganese are examples of trace elements. It is a martensitic grade that is free-machining and heat-hardenable. In general, SS 416 tubing has an elongation of 15–25%, a yield strength of roughly 275 MPa, and a tensile strength of 550–760 MPa. It is appropriate for parts that need precision machining and moderate strength in dry or mildly corrosive environments because it offers fair toughness, excellent machinability, and moderate corrosion resistance.
