Hot sale 50CrMo4 steel plate material in the steel market

ASME SA 53 seamless pipe is manufactured according to 50CrMo4 steel plate ASME code. Because it belongs to low carbon steel, the surface hardness can only be improved by carburizing. If you are interested in BBN 50CrMo4 steel plate ASTM A53 or ASME SA 53 carbon seamless pipe, please contact us for the latest price.

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the 50CrMo4 steel plate industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the 50CrMo4 steel plate industry with scientific management, high quality, first-class service and harmonious development

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the 50CrMo4 steel plate steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of 50CrMo4 steel plate seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

The microstructure of the quenched and tempered alloy steel, 50CrMo4 steel plate after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
