Stainless Steel Seamless Pipes / Tubes

The properties of stainless steel are corrosion resistance, high ductility, attractive appearance and low maintenance.

Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.
