Stainless Steel Seamless Tubes

Stainless steel is often referred to as "corrosion-resistant steel" – it does not stain, corrode or rust as easily as normal carbon steel. It would however be misleading to say it is corrosion-proof. It differs significantly from standard carbon steel due to the amount of chromium present, which limits surface corrosion unlike carbon steel which will rust when exposed to air and any moisture in the atmosphere. Due to its anti-oxidation qualities, stainless steel is often a popular solution.

While manufacturing ERW steel Tubes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel Tubes and tubing possess high strength corrosion resistance, high deformability, high strength and high toughness. We are among the leading manufacturers and suppliers of ERW Tubes and tubes in India. We are also one of the largest exporters of ERW Tubes and tubes in India. ERW Tubes and tubes stands for electric Resistance Welded Tubes and tubes.
