Product Introduction

Stainless Steel Sheet Hot Rolled 321

Stainless steel sheet hot rolled 321 is an austenitic stainless steel known for its excellent high-temperature corrosion resistance and strength. It is extensively used across various industries such as petrochemical, power, bridge construction, and automotive, particularly for welding components in high-temperature settings like engine exhaust pipes, boiler casings, heat exchangers, and furnace parts. Additionally, it is suitable for outdoor machinery in the chemical, coal, and petroleum industries, as well as for construction materials that demand high heat resistance and are difficult to heat-treat. The steel plate comprises carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel, and titanium in an amount at least five times that of carbon, which contributes to its high tensile and yield strengths and good elongation rate.
