In terms of service, our service is a "one-stop" way of working. We have our own A283 Gr D CS steel carbon plate processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as A283 Gr D CS steel carbon plate cutting, welding, drilling, galvanizing, etc., at the lowest cost.
A36 steel plate contains different amounts of other materials such as carbon, nickel, manganese, tungsten and molybdenum. Different components in A283 Gr D CS steel carbon plate A36 steel plate will produce different properties. The modulus of elasticity (i.e. hardness measurement) of all A36 plates is 29 million psi.
We have many kinds of boiler and pressure vessel steel materials, including ASTM, ASME, DIN, JIS, en, GB and other multinational standards, dozens of steel grades. Customers have a wide range of options. At the same time, we have obvious advantages in wide and thick plates. The widest boiler plate can be more than 5 meters. The A283 Gr D CS steel carbon plate and pressure vessel steel price is also competitive, and there is a professional team to serve you.
The hot rolling method is to heat the A283 Gr D CS steel carbon plate steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of A283 Gr D CS steel carbon plate rolling process is usually called semi-finished product production, also called blank production.
Heat treatment specification and microstructure of A283 Gr D CS steel carbon plate, 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).
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
