Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing.

Material stainless steel grades

ASTM A789 & A790

ASTM A789 & A790: American Society for Testing and Materials
Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service
Application: Refineries; Nuclear Plant; Aerospace Industry; Chemical Fertilizer; Petrochemicals’ Oli & Gas and etc.

ASTM A789 covers duplex stainless steel (UNS S32205, S31803) tubing for general corrosion-resisting and low or high-temperature services.

ASTM A790 covers seamless and welded ferritic/austenitic stainless steel (UNS S31803, S32205, S32750, S32760) tubing for general corrosion-resisting and low or high-temperature services.
