SS 347 Stainless Steel Sheets Manufacturer
What are SS 347 Stainless Steel Sheets?
SS 347 stainless steel sheets are austenitic stainless steel sheets stabilized with niobium (columbium), which prevents carbide precipitation during welding and high-temperature service. SS 347 offers excellent resistance to intergranular corrosion, especially after welding, and is ideal for high-temperature operations up to 900°C (1650°F) in oxidizing environments.
