Premium-grade stainless steel 316H sheets and plates, designed for high-temperature and high-pressure applications, are available from Kunj Sheets and Plates, a well-known manufacturer and supplier in Chennai, India. 316H, a high-carbon version of the 316 stainless series, is renowned for its exceptional strength, resistance to corrosion, and longevity. These plates and sheets are supplied by Kunj in a range of sizes and finishes that are tailored to satisfy particular industrial requirements. In India and international markets, Kunj is a reliable partner for sectors like petrochemical, power generation, pharmaceuticals, and marine applications thanks to its dedication to quality, prompt delivery, and technical know-how.
With a higher carbon content (0.04–0.10%), 10–14% nickel, 2–3% molybdenum, and 16–18% chromium, stainless steel 316H is stronger at higher temperatures. In chloride environments, it provides outstanding resistance to pitting, crevice corrosion, and general wear. The alloy has a tensile strength of 515–690 MPa, yield strength around 205 MPa, and elongation of 40%. 316H is perfect for use in settings with high mechanical stress and temperatures above 500°C because of its strong mechanical characteristics, which also include high creep and stress rupture resistance.

Stainless Steel 316H Sheet and Plates offers several key benefits, especially in high-temperature environments. Its high carbon content also increases creep resistance, making it ideal for structural application in the chemical, petrochemical and marine industries. The material boasts excellent corrosion resistance, especially against chloride, pitting and crevice corrosion. It also performs well in extreme temperatures, maintaining its integrity in high temperature conditions. In addition, stainless steel 316H is durable, easy to manufacture, and highly resistant to oxidation, providing long service life with minimal maintenance These properties make it ideal for environmental production difficult to destroy.
Heat exchangers, pressure vessels, boiler parts, and reactors used in the chemical and petrochemical industries are all excellent candidates for stainless steel 316H sheets and plates. They are appropriate for high-temperature applications due to their increased carbon content, especially in thermal processing systems, nuclear power plants, and oil and gas refining. They offer outstanding resistance to salty water and severe weathering conditions in the marine industry. Additionally, 316H is utilised in pulp and paper mills, pharmaceutical companies, and food processing machinery where corrosion resistance, strength, and hygienic conditions are critical. It is a dependable industrial-grade material due to its durability and weldability.
