heat treatment of p355gh Carbon Steel Supplier

Pageviews:

The company is a leading company that sells heat treatment of P355GH steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold heat treatment of p355gh steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

A633GrD steel plate is suitable for normalized high-strength low-alloy structural steel plate for tower connection or source bolt connection structure. A633GrD steel plate should be normalized: heat the steel plate to a suitable temperature that can produce austenite structure but does not exceed 1700F [925℃], and keep it at this temperature for a period of time, so that the entire heat treatment of p355gh plate can be uniformly heated, and then left in the air Cool with medium.

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.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized heat treatment of p355gh are higher than that of annealed heat treatment of p355gh, but the elimination of internal stress is not as good as annealing. The normalizing operation of heat treatment of p355gh is simple, the cost is low, the productivity is high, and it is widely used in actual production.

The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. heat treatment of p355gh, 20CrMo steel pipe is generally used in quenching and tempering state.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
