SS 321 Stainless Steel Sheets Manufacturer
What are SS 321 Stainless Steel Sheets?
SS 321 stainless steel sheets are titanium-stabilized austenitic stainless steel sheets that offer excellent intergranular corrosion resistance and high-temperature stability. The addition of titanium prevents carbide precipitation during welding and extended exposure to temperatures up to 900°C (1650°F), making it ideal for use in heat exchangers, exhaust systems, and pressure vessels.
