The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

The purpose of 42CrMoS4 free-cutting steel carbon content quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of 42CrMoS4 free-cutting steel carbon content. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of 42CrMoS4 free-cutting steel carbon content, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.

The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
