Performance and application of material ST37: the material has good performance, that is, through cold rolling, it can obtain cold rolled strip and steel plate with thinner thickness and higher precision, with high straightness, high surface finish, clean and bright surface of cold rolled plate in Taiwan Strait.
SS400 is a Japanese steel grade, commonly used for ordinary steel bars and galvanized iron wire. The hardness of the supply status is around HB178, where 400 represents σ The small value of b is 400MPa, which refers to ultra-high strength steel σ Steel with b ≥ 1373 Mpa.
C45 carbon steel is a type of medium carbon high-quality steel with high strength. Due to poor hardenability, it is generally used in a normalized state. When high mechanical properties are required, quenching and tempering treatment is used.
S235JR is a European standard carbon structural steel plate that complies with EN10025 standard. The carbon content of S235JR round steel carbon structural steel is less than 0.8%.
4140 carbon steel round bar is a commonly used alloy steel with a series of characteristics and wide applications. It improves the strength and hardness of steel by adding alloying elements to ordinary carbon steel.
