Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the A588GrC tensile strength project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of A588GrC tensile strength customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This A588GrC tensile strength production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate A588GrC tensile strength size.
Heat treatment specification and microstructure of A588GrC tensile strength, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).
Company through its own A588GrC tensile strength website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.
