SS 420 Tube

SS 420 is made of 420-grade stainless steel, a higher carbon version of stainless steel which can be heat-treated. The tube SS420 contains at least 12% chromium, enough to give tube SS 420 resistance to corrosion.

The 420 tube of infinite steel is a straight chromium steel that is not hardenable and is a ferritic group of steels. Stylish steel 420 tube, combined with practical mechanical properties, is known for its good corrosion, formability and formability. Stainless steel 420 tubes improve their corrosion resistance by their molybdenum content.

SS 420 tubes also have extraordinary resistance to stress corrosion cracking.
