The mechanism of 304 stainless steel tube is not oxidized
Chromium has high chemical stability, can form a passivation film on the steel surface, metal and isolated, 304 stainless steel tube can protect the steel pipe from oxidation and improve the corrosion resistance of the steel pipe.
Suitable for components with a maximum operating temperature of 1200 ° C, so that the furnace 316L stainless steel tube, continuous use temperature of 1150 ° C. Stainless steel tube, which belongs to the textile equipment accessory, is connected by a cylindrical cylinder to the end plate of the cylinder, and the end plate of the end plate is composed of two layers of stainless steel outer end plates, steam holes of the cylinder wall made of stainless steel, and The sleeve or shaft is mounted on the end plate and the hole is connected to the rotating shaft for convenient use.
The 304 stainless steel tube has a maximum carbon content of 0.03 and can be used for welding without annealing and maximum corrosion resistance. This plan is based on the stainless steel hardness Rockwell hardness test, only two HRC, HRB are provided in the stainless steel standard. The annealed stainless steel material generally corresponds to the hardness value of each grade of stainless steel should be less than a certain value HRB, generally in the range of 8896hrb. The quenching and tempering of martensitic stainless steel generally corresponds to each grade of stainless steel, and the specified hardness value is not less than the hardness value, generally 32 to 46 HRC. For the hydraulic test of steel subjected to pressure to test its pressure resistance and quality, leakage, qualified wet expansion or does not occur at the predetermined pressure, some steel pipe and flange test, flare test, flattening test according to the buyer's standard Or request.
