High strength 20CrMo alloy steel plate

What is the 20CrMo alloy?
20CrMo alloy steel plate is ultra-high strength steel, with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, good low temperature impact toughness. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. The 20CrMo steel equivalent: corresponding to Germany: 42CrMo4, corresponding to the United States: 4140, corresponding to Japanese SCM440. Heat the 20CrMo alloy steel plate to a temperature above 30-50 ° C above the temperature at which all the ferrite is transformed into austenite, keep it warm for a period of time, and then slowly cool it with the furnace. During the cooling process, the austenite transforms again to make the steel structure. The workpiece is heated to 20-40 ° C above the temperature at which the 20CrMo alloy steel plate begins to form austenite, and then slowly cooled after heat preservation. During cooling, the lamellar cementite in the pearlite becomes SPHErical, thereby reducing the hardness.

What is the advatages of 20CrMo alloy?

20CrMo alloy steel plate's advantages are mainly reflected in its physical and chemical properties. For the 20CrMo alloy plate, its main component is the alloy. The physical and chemical properties of the alloy are better than the general single metal, and the performance is more robust. The features of 20CrMo alloy plate are mainly high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics. For the 20CrMo alloy steel plate, it is necessary to continuously enhance the stability of its various properties, and to protect its normal use is very important to the meaning of the 20CrMo alloy plate.

What is the application 20CrMo alloy?

20CrMo alloy steel plate plays a decisive role in construction, it must have sufficient strength and stability to assume the safety of the house. 20CrMo alloy steel plate is often used in large buildings that require large bearing capacity and good cross-section stability, as well as bridges, ships, and lifting and transportation machinery.
