introduction

A333 seamless steel pipe is a metal material widely used in petroleum, chemical industry, electric power and other fields.
A333 seamless alloy steel pipe has high strength and hardness, and has good plasticity and toughness. At room temperature, its tensile strength can reach 500~700MPa, yield strength is 270~410MPa, and elongation is 18%~22%. At lower temperatures, its strength and hardness will not be significantly reduced, while having good impact resistance and fatigue resistance.
The main components of A333 low temperature steel pipe include iron, carbon, chromium, nickel, manganese and other elements. Among them, chromium has excellent corrosion resistance, while the addition of nickel further enhances the corrosion resistance and toughness of the material. In addition, A333GR.6 seamless steel pipe also contains a certain amount of silicon, phosphorus, sulfur and other elements, which have a certain impact on the mechanical properties and processing properties of the material.
