Stainless Steel Round Pipe 2 to 4 Inches Thickness Large SS Pipes

304 Stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending without heat treatment Hardening phenomenon (use temperature -196℃~800℃). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. Has good processing properties and weldability.
