Welcome to BBN High Strength Steels Factory
45Mn2 steel is added with manganese on the basis of No. 45 steel. After quenching and high temperature tempering, 45Mn2 steel can obtain high strength and good toughness, that is, it has good comprehensive mechanical properties, and is often used in manufacturing larger load shafts, connecting rods, fasteners, etc. The price of 45Mn2 steel is higher than that of No. 45 steel, S960Q steel tube. And the performance of 45Mn2 steel after heat treatment is better. 45Mn2 steel can be used as parts under higher stress and wear conditions, such as universal joint shaft, axle, connecting rod cover, friction plate, etc. The performance of 45Mn2 steel after heat treatment is better than No. 45 steel and worse than 40Cr steel.
The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, S960Q steel tube. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.
Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For S960Q steel tube medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
Keep close relationship with all manufacturers and users, cooperate sincerely, share weal and woe together. We are deeply tolerant of travelling with you! We value and value each other's career and friendship. No matter when and where, all our staff will spare no effort to put into the work, and do their best to provide S960Q steel tube satisfactory services for all friends, so as to achieve win-win and multi win for each other.
