A573 Gr 70 carbon steel,BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.
Wear resistant steel plate is a kind of special plate product specially used under the condition of large area wear. At present, the commonly used wear-resistant steel plate is a plate product made by overlaying a certain thickness of hard and wear-resistant alloy wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. The wear-resistant steel plate consists of two parts: carbon steel plate and alloy wear-resistant layer.
A573 Gr 70 carbon steel,Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor This 20Cr alloy steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness,A573 Gr 70 carbon steel.
A573 Gr 70 carbon steel,Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the 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 quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.A573 Gr 70 carbon steel
