One is the steel mill in the production of stainless steel rolling through the rolling mill, the main thickness of these products in the 3-6mm or so, is hot-rolled after the state of acid wash, the process is as follows: Stainless steel billet → hot rolling mill rolling black roll → hot anneal...

In the welding of stainless steel rod workpiece, the choice of stainless steel welding should pay attention to the following issues: 1, chrome stainless steel has a certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat and wear resistance. Usually used for power plants, ch...

Stainless steel capillary at the annealing tube temperature is to reach a certain temperature. 1, stainless steel capillary at the annealing tube temperature is to reach a certain temperature. Stainless steel heat treatment is generally accepted solution heat treatment, popular talk is "anne...

304L stainless steel chemical chemical composition% C: ≤ 0.03, Si: ≤ 1.0, Mn: ≤ 2.0, Cr: 17.0 ~ 19.0, Ni: 8.0 ~ 11.0, S: ≤0.03, P: ≤0.035. 304 stainless steel Chemical composition C≤0.08 Si≤1.00 Mn ≤2.00 P≤0.05 S≤0.03 Cr 18.00-20.00 Ni (nickel) 8.00 ~ 10.50 – 304 stainless steel and 304L s...

Stainless steel is less containing 50% iron and 10.5% chromium, and also added such as nickel, titanium, molybdenum, etc., according to the different composition of the suspension, the metal within the different microstructure, which is martensitic, Body type, austenite type, biphasic, precipitat...

316 stainless steel materials generally do not have pipe material, this thing with less, unlike ordinary steel pipe can be prepared, the other 316 stainless steel tube prices are high, so are generally custom. Although the 316 is divided into the national standard 316L and American Standard TP31...

4. Welding hot cracking (weld crystal crack, heat affected zone liquefaction cracking) Thermal cracking sensitivity depends primarily on the chemical composition, organization and properties of the material. Ni and S, P and other impurities to form low melting compounds or eutectic, boron, silico...

Austenitic stainless steel in the welding characteristics: the welding process of the bomb, plastic stress and strain is very large, but rarely cold cracks. Weld joints do not exist hardened hardening zone and grain coarsening, so the weld tensile strength is high. Austenitic stainless steel wel...

We should not pay attention to the processing of stainless steel punching net products, the product processing area should be relatively fixed. Stainless steel perforated mesh processing area of ​​the platform should be taken to isolate, such as covered with rubber pads and so on. Stainless steel...

Welded joints of the knife-like corrosion Precautions: Due to the strong diffusion of carbon, in the cooling process will be segregated in the grain boundary to form a supersaturated state, and Ti, Nb due to low diffusion capacity and stay in the crystal. When the welded joint is heated again in ...

1. The formation of chromium carbide reduces the resistance to intergranular corrosion of welded joints. Intergranular corrosion: According to the theory of poor chromium, welds and heat affected zone in the heating to 450-850 ℃ sensitized temperature zone in the grain boundary precipitation of c...

Stainless steel square tube is a hollow long steel, because the section is square so called square tube. A large number of pipes used for conveying fluids, such as oil, natural gas, water, gas, steam, etc., in addition to bending, torsion strength of the same, the lighter weight, it is also widel...
