Focusing on quality, innovation, and customer satisfaction, the company provides high-performance stainless steel bars suited for industrial applications where performance matters. Harsh Metalloys’ Stainless Steel 321 bars have an excellent resistance to oxidation as well as intergranular corrosion, especially in high-temperature conditions. With the aid of sophisticated manufacturing technology and rigorous quality control measures, Harsh Metalloys supplies robust, precision-engineered products to customers in India and worldwide, positioning itself as a go-to partner for high-quality stainless steel bar solutions.
Harsh Metalloys’ stainless steel 321 bars in Mumbai, India, consist of 17–19% chromium, 9–12% nickel, and titanium, which stabilizes the alloy against intergranular corrosion. This austenitic stainless steel possesses superior high-temperature properties and resistance to oxidation. The bars possess a tensile strength of about 515 MPa and a yield strength of about 205 MPa, along with excellent creep and stress rupture resistance. Such mechanical qualities, coupled with resistance to corrosion, render SS 321 bars best suited for processes that carry out repeated thermal cycling. Harsh Metalloys provides uniform quality and performance by conducting stringent testing and manufacturing accuracy.
