a573 grade 70 and a516 grade 70 steel plates cold rolled steel plate

100Cr6 bearing steel has good toughness, good tempering stability, and small deformation during heat treatment. The carbides in the steel are evenly distributed, it is not easy to precipitate carbide nets, and it is easy to eliminate normalizing. Through normalizing, the network and coarse carbide structures can be eliminated. a573 grade 70 and a516 grade 70 steel plates, 100Cr6 bearing steel can be used to manufacture measuring tools, molds, woodworking tools.

For a573 grade 70 and a516 grade 70 steel plates, wear-resistant plate, the change of temperature in production and processing will directly affect the properties of the whole plate, so the effect of isothermal treatment of wear-resistant steel plate has been studied all the time. The results show that the continuous cooling transformation curve, microstructure, phase and similar structural phase of wear-resistant plate also change under different heating temperature.

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 a573 grade 70 and a516 grade 70 steel plates are higher than that of annealed a573 grade 70 and a516 grade 70 steel plates, but the elimination of internal stress is not as good as annealing. The normalizing operation of a573 grade 70 and a516 grade 70 steel plates is simple, the cost is low, the productivity is high, and it is widely used in actual production.
