The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product carbon steel plate A283 gr.c more than 15 years.
C45 steel is a medium carbon high quality steel with high strength. Chemical composition of C45 steel: C: 0.42 - 0.50, Si: ≤ 0.40, Mn: 0.50 - 0.80, S: ≤ 0.045, P: ≤ 0.045, Cr: ≤ 0.40, Ni: ≤ 0.40, Mo: ≤0.10. carbon steel plate A283 gr.c, C45 steel is widely used in aerospace, electric power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries.
The company has created a group of professional staff with good market awareness and service spirit. More than 90% of the company's employees have college education and more than 3 years of work experience in the industry. Our company has a group of senior professionals engaged in international cargo transportation. Through the implementation of modern centralized control management of the carbon steel plate A283 gr.c whole system computer network, we can effectively control and guarantee the daily operation of the carbon steel plate A283 gr.c.
The tempering of carbon steel plate A283 gr.c steel plate, the hardened steel will be reheated to a certain temperature, and then a certain method of cooling is called tempering.Its purpose is to eliminate the internal stress caused by quenching, reduce hardness and brittleness, so as to achieve the desired mechanical properties. Tempering is divided into three types: high temperature tempering, medium temperature tempering and low temperature tempering.Tempering and quenching, with the use of normalizing.
