Product Overview
201 stainless steel pipe is a nickel-free austenitic stainless steel pipe material, designed with a high manganese and low nickel composition. It combines excellent processing performance, corrosion resistance and economy, and is a cost-effective alternative to 304 stainless steel pipes.
It has the characteristics of light weight and high strength, good formability, and can be processed into complex structural components through bending, stamping and other processes. It is widely applicable in scenarios such as structural support, fluid transportation and decoration projects in general corrosive environments, and is a commonly used pipe material in the industrial and trade fields that balances cost and performance.
