Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality SS 310H Sheets and Plates. Known for precision engineering and strict quality standards, Walid Stainless delivers stainless steel products built for extreme temperature applications. SS 310H is a high-carbon version of the 310 grade, offering superior strength and stability at elevated temperatures. These sheets and plates provide excellent oxidation resistance, durability, and long-term performance in severe thermal environments. With a strong commitment to international standards and customer satisfaction, Walid Stainless supplies reliable materials for critical industrial operations.
SS 310H Sheets and Plates contain approximately 24–26% chromium and 19–22% nickel, with increased carbon content to enhance high-temperature strength. This composition offers outstanding resistance to oxidation and scaling at temperatures up to 1100°C. These products typically exhibit tensile strength in the range of 520–750 MPa and yield strength around 215–310 MPa. SS 310H maintains excellent hardness, toughness, and structural integrity under prolonged heat exposure, pressure, and thermal cycling conditions.
