What is 42CrMoS4 carbon equivalent equivalent material in China
The 42CrMoS4 carbon equivalent plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The 42CrMoS4 carbon equivalent products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
Main properties of 20CrMn steel plate: high strength and toughness, and good hardenability. The performance obtained after heat treatment is better than 20Cr. The quenching deformation is small, the low temperature toughness is good, and the machinability is good; but the welding performance is low. Generally used after carburizing, quenching or quenching and tempering. 20CrMn steel is used for manufacturing and heavy-duty hardened and tempered parts with large cross section and carburized parts with small cross section.
There are many advantages of 42CrMoS4 carbon equivalent, pickling coils. The surface of pickling coil is smooth, and the outside is very beautiful. From the appearance, we can see how the manufacturer's technology is, and it is convenient to use pickling coils in engineering. In addition, the cost can be reduced by using pickling coil instead of cold rolled sheet. The corrosion resistance of pickling coil is better than ordinary steel plate, and its service life is also very long.
When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, 42CrMoS4 carbon equivalent, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of 42CrMoS4 carbon equivalent, SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.
