Our company's P295GH equivalent grades power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the p295gh equivalent grades utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

45# seamless steel pipe (No.45 seamless steel pipe) is Chinese high-quality carbon structural steel, which is called S45C in Japanese standard, AISI 1045 in American standard, and C45 in German standard. The difference between 45# seamless steel pipe and 20# seamless steel pipe is that its hardness is obviously higher than that of 20# seamless steel pipe. The tempering brittleness of p295gh equivalent grades, 45# seamless steel pipe is high. After quenching and tempering, 45# seamless steel pipe has good mechanical properties. If the wear resistance is considered, heat treatment is required.

Cold rolled coil products p295gh equivalent grades have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products p295gh equivalent grades is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils p295gh equivalent grades with different surface roughness can be produced (glossy surface or matte surface, etc.).

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the p295gh equivalent grades quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After p295gh equivalent grades quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
