A514 Gr A alloy steel plate,Q370q steel is a kind of bridge steel plate It is delivered in hot rolled, normalized condition There are three quality levels Q370qC, Q370qD, and Q370qE Bridge steel Q370qC, Q370qD, and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃ Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated When mechanical properties are required, large thickness must be normalized The thickness of Q370q steel plate we supply is above 8mm,A514 Gr A alloy steel plate.
Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.
Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.A514 Gr A alloy steel plate
S355J0 steel density is 7.85g/cm³. S355J0 density represents the mass per unit volume of S355J0 steel, which indirectly affects the price of S355J0 steel. Therefore, the density of S355J0 is also an important consideration for material selection. S355J0 steel tensile strength (σb / MPa):3<t≤16MM (thick) 470-630; 16-<t≤140MM (thick) 470-630, 40<t≤163MM (thick) 470-630, 63<t≤180MM (thick) 470-630. Yield point (σs / MPa):3<t≤116MM (thick) ≧ 355; 16<t≤140MM (thick) ≧ 345; 40<t≤163MM (thick) ≧ 335; 63<t≤180MM (thick) ≧ 325.
