What is the hardox 400 china manufacturer impact test

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 HARDOX 400 china manufacturer whole system computer network, we can effectively control and guarantee the daily operation of the HARDOX 400 china manufacturer. The company is dedicated to provide customers with safe, convenient, economic and thoughtful freight service. The company has always followed the principle of "people-oriented", and created a group of professional staff with good market awareness and service spirit.

Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. HARDOX 400 china manufacturer, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. HARDOX 400 china manufacturer, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

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 HARDOX 400 china manufacturer alloy steel HARDOX 400 china manufacturer 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.

The effect of nitrogen (N) on the properties of HARDOX 400 china manufacturer and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in HARDOX 400 china manufacturer and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

High quality mild steel sheet and plate product HARDOX 400 china manufacturer supply 10.5*1970*7950, 13*1300*4350, 11*1900*12500, 12.5*2870*7100, 11*1870*12500, 10.5*1970*8000, 13*1520*7950, 11*1910*9000, 12.5*2900*8250, 11*1870*13500, 10.5*2350*6200, 14*1440*6100, 11*3100*10000, 13*1510*4850, 11*1870*9300, 11*1570*12000, 14*1800*9750, 11.5*2640*7600, 13*2380*6000, 11*2400*10000.

Hot rolled plates are known for their superior mechanical properties over commodity grades of merchant bar. The hot rolled HARDOX 400 china manufacturer plates products are made to specific chemistry and mechanical properties ranges, allowing them to be used in engineered applications. Resulting shafts, axles, and gears can be used in the automotive HARDOX 400 china manufacturer industry and agriculture equipment. A36 mild steel has good strength, formability, and excellent welding properties. We also can supply welding, fabricating, and bending service.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
