Hardenability of 34CrMo4 plate to EN 10083-3 after quenching and tempering
The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, 34CrMo4 plate to EN 10083-3 steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and 34CrMo4 plate to EN 10083-3 carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.
Compared with ordinary steel, structural steel has the following differences. First, the strength of structural steel is high, and its bearing capacity is far greater than that of ordinary steel. Second, the structural steel has low impurity and carbon content, uniform material and good performance. Third, structural steel has light weight and is suitable for building various frames. Fourth, it is convenient to build structural steel, which is conducive to construction efficiency and reduces construction time. In some construction fields, structural steel must be used. Where can we find 34CrMo4 plate to EN 10083-3, structural steel suppliers?
Just as 34CrMo4 plate to EN 10083-3, the boiler steel plate also has strict control of chemical composition for the material, especially harmful elements such as phosphorus and sulfur, and residual elements such as chromium, nickel, and copper; during smelting, good deoxidation and removal of non-metallic inclusions should be carried out to ensure good quality, plasticity and toughness. The organizational structure requires uniformity, and the grain size is controlled within a certain range; there are also strict requirements for surface quality and internal defects. In addition, the boiler steel plate mechanical properties at room temperature and high temperature must be guaranteed.
The main function of boron in 34CrMo4 plate to EN 10083-3 and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.
