Product Description

Stainless steel is an alloy material composed of iron, chromium, nickel and other elements. It not only has excellent corrosion resistance and chemical stability, but also has physical properties such as light weight and easy processing.

Stainless steel pipes are hollow long circular steel materials made of stainless steel. They inherit all the characteristics of stainless steel and are widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemicals, medical, food, light industry, ships, mechanical instruments, etc.
