Large diameter stainless steel seamless welded pipe is a kind of long steel with hollow section and no seam around. Kuanyu large diameter 316 stainless steel seamless steel pipe customized, free cutting! * * 316 stainless steel seamless steel pipe * * supplier, annual sales over 100 million!

Structural seamless steel pipe (GB / T8162-1999) is a kind of seamless steel pipe used in general structure and mechanical structure.

Seamless steel pipe for fluid transportation (GB / t8163-1999) is a general seamless steel pipe used to transport water, oil, gas and other fluids. Chemical properties: chemical corrosion resistance and electrochemical corrosion resistance in steel is second only to titanium alloy.

Physical properties: heat resistance, high temperature resistance, low temperature resistance and even ultra low temperature resistance.

Mechanical properties: according to different types of stainless steel, the mechanical properties are different. Martensitic stainless steel has high strength and hardness, which is suitable for manufacturing parts with corrosion resistance, high strength and high wear resistance, such as turbine shaft, stainless steel cutting tool, stainless steel bearing, etc. austenitic stainless steel has good plasticity and low strength, but its corrosion resistance is among stainless steel, which is suitable for the requirements It can also be used in military industries such as submarines. Ferritic stainless steel has moderate mechanical properties and low strength. However, it is resistant to oxidation and is suitable for various industrial furnace parts.

Process performance: austenitic stainless steel process performance, due to good plasticity, can be processed as a variety of plates, tubes and other profiles, suitable for pressure processing, martensitic stainless steel due to high hardness process performance.
