Do a good job of thought introduction based on people. Human based management is the most important link in standardizing employee behavior management. In daily behavior management, we should establish the central position of human and play an important role of human. Employees are not only the builders and exercisers of corporate culture, but also the executors of code of conduct. The code of conduct should be finally implemented into the thoughts and actions of employees.
Chemical composition(%) of A213 T36 steel pipe(Carbon: 0.10–0.17, Manganese: 0.80–1.20, Phosphorus: 0.03, Sufur: 0.025, Silicon: 0.25–0.50, Nickel: 1.00–1.30, Chromium: 0.3, Molybdenum: 0.25–0.50, Vanadium: 0.02, Niobium: 0.015–0.045, Nitrogen: 0.02, Aluminum: 0.05, Cu 0.50–0.80). Mechanical properties for A633 Grade A impact test, A213 T36 steel pipe: Tensile strength(min): 415Mpa; Yield strength(min): 205Mpa; Elongation: 30%; Hardness, HB: 163max.
Vanadium mainly exists in the form of carbide in A633 Grade A impact test and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron A633 Grade A impact test production excluding China was 36.309 million tons, a year-on-year decrease of 11%. In March, except for China and Russia, pig iron production increased by 1%6, other countries' pig iron A633 Grade A impact test production decreased year-on-year, with 28 EU countries reducing by 14.2%, 3 CIS countries (Russia, Ukraine and Kazakhstan) reducing by 0.8%, India reducing by 14.6%, Japan reducing by 7.9% and South Korea reducing by 9.5%.
