What is JIS SM400A plates

JIS SM400A plates annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of JIS SM400A plates annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. JIS SM400A plates annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Q960 quenched and tempered steel grade classification: Q960C, Q960D, Q960E, Q960F. The product JIS SM400A plates thickness is not more than 150MM. Q960 quenched and tempered steel has high yield strength and tensile strength, and its resistance to brittle failure is also great. Q960 quenched and tempered steel has excellent low temperature toughness, so it can be used in large welded structural parts and low temperature environments.

The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel JIS SM400A plates, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.

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 JIS SM400A plates 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.
