China supply chemical composition of NM450 impact toughness
Tata Steel Europe plans to cut 1250 jobs. Henrik Adam, CEO of Tata Steel, said: "the financial situation of Tata Steel Europe is very serious at present, and there is an urgent need to improve the company's performance and financial situation." Tata Steel has decided chemical composition of NM450 in November 2019 to cut 3000 jobs in its European operations to reduce costs. After a period of negotiations with the European labour Commission, the layoff plan cut that number by more than half, minimizing unemployment. Tata Steel has about 20000 employees in Europe.
The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.
The mechanical properties of 20MnV steel are as follows: tensile strength 785 MPa, yield strength 590 MPa, elongation after fracture 10%, reduction of area 40%, impact absorption energy 55 J. chemical composition of NM450, 20MnV steel has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel is good, but there is temper brittleness at 300-360 ℃ during heat treatment.
As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's chemical composition of NM450 steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole chemical composition of NM450 steel transportation industry.
The final heat treatment of quenched and tempered alloy steel, chemical composition of NM450 is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
