igh quality nm500 sheet strips dimension

The difference between q345 and q235 steel igh quality NM500 sheetThe lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.
The company is committed to providing customers with high-quality and low-cost igh quality NM500 sheet steel products as the goal, striving to create value for customers as its own responsibility. With advanced Kaiping processing equipment and strong logistics distribution system, the company can meet the needs of customers at any time. The company has the advantages of igh quality NM500 sheet complete specifications, low price and fast distribution, With the service concept of keeping promise and valuing quality, it has won the trust and unanimous praise of the majority of users. The scale and strength of the enterprise is in the forefront of domestic metal material business units.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the igh quality NM500 sheet 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 igh quality NM500 sheet quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
igh quality NM500 sheet, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.
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.
