Located in Mumbai, India, Harsh Metalloys is a top producer and supplier of high-grade stainless steel 310H sheets and plates, which are renowned for their exceptional corrosion resistance and high temperature strength. Modern technology and premium raw materials are used in the production of these goods, guaranteeing adherence to global standards. Under extremely high temperatures, SS 310H sheets and plates provide exceptional durability, oxidation resistance, and structural integrity. Good for many industrial uses, Harsh Metalloys provides customers around the world with dependable, high-performing solutions supported by prompt delivery, quality control, and a dedication to going above and beyond for clients.
Compared to 310/310S, stainless steel 310H sheets and plates have a higher carbon content (≥0.04%), 24–26% chromium, and 19–22% nickel, which improves their creep strength and high-temperature performance. Up to 1100°C, these materials show exceptional resistance to oxidation. Mechanical characteristics include a 40% elongation, a yield strength of 205 MPa, and a tensile strength of roughly 515 MPa. SS 310H sheets and plates are appropriate for structural and pressure-containing applications in high-temperature environments because of the alloy’s structure, which guarantees stability under thermal stress and resistance to scaling.
