Large diameter thick wall stainless steel pipe Product introduction:


    Stainless steel is a kind of high alloy steel which can resist corrosion in air or chemical corrosive medium. From the metallographic point of view, because the stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the oxygen invading into the steel and plays a role of corrosion resistance.


Stainless steel seamless steel pipe It has good intergranular corrosion resistance, excellent corrosion resistance, cold working and stamping properties, and can be used as heat-resistant stainless steel. At the same time, the steel in the -180 Its mechanical properties are still good at ℃. In the solution state, the plasticity, toughness and cold workability of the steel are good; It has good corrosion resistance in oxidizing acid, atmosphere and water. The main characteristics of seamless stainless steel pipe: corrosion resistance, high temperature resistance, low temperature resistance, tensile strength, low temperature impact, flattening, expanding, no cracking when bending.
