Based in Delhi, India, Harshita Stainless is a well-known producer and supplier of stainless steel 409 coils, providing premium and reasonably priced solutions for a range of industrial and automotive applications. Ferritic stainless steel SS 409 is well-known for its exceptional weldability, corrosion resistance, and thermal stability, making it the perfect choice for applications requiring moderate oxidation and corrosion protection. Harshita Stainless guarantees that every coil is produced in accordance with international quality standards and exact tolerances. The company serves industries like automotive, exhaust systems, heat exchangers, and structural components in both domestic and international markets thanks to its robust distribution network and customer-focused philosophy.
The main constituents of stainless steel 409 coils are iron and chromium (10.5–11.7%), with trace amounts of carbon (≤0.08%), silicon, manganese, and titanium (as a stabiliser). Particularly in mild conditions, this ferritic alloy provides good resistance to oxidation and corrosion. Mechanically, SS 409 offers elongation of 20% or more, yield strength of 170–240 MPa, and tensile strength of roughly 380–450 MPa. It is appropriate for applications requiring moderate temperatures due to its exceptional formability, weldability, and thermal conductivity. For many industrial applications, it provides a cost-effective performance, despite having a lower resistance to corrosion than austenitic grades.
