The advantages of ASTM A572 high strength steel, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.
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 ASTM A572 high strength steel 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.
Ordinary ASTM A572 high strength steel carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the steel, and generally does not add a lot of alloy elements. Ordinary carbon steel is the abbreviation of ordinary carbon structural steel. Carbon content is less than 0.38%, and less than 0.25% is the most commonly used. It belongs to low carbon steel. In the Chinese standard, each metal grade indicates the low yield point of the steel when the thickness is less than 16mm. Compared with high-quality carbon steel, the limitation of carbon content, performance range, phosphorus, sulfur and other residual elements is wider for ordinary carbon steel.
