Stainless Steel Plate and Coil – Type 304H is a versatile and widely used material for various industries due to its excellent high-temperature strength, corrosion resistance, and creep resistance. Its high carbon content and chromium-nickel austenitic stainless steel alloy composition provide a high level of resistance to corrosion in oxidizing and reducing environments, making it suitable for harsh environments. The addition of nickel enhances its corrosion resistance and formability.
