We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product A588 Gr B HSLA steel plate annual capacity is 200 thousand tons.
In the first ten days of February 2020, the key statistics show that steel enterprises produce a total of 19.3943 million tons of crude steel, 17.9747 million tons of pig iron, 17.5904 million tons of steel and 3.225 million tons of coke. This ten day average daily output of A588 Gr B HSLA steel plate crude steel is 1939400 tons, down 2.68% on a month on month basis, up 3.16% on a year-on-year basis; steel is 1759000 tons, down 9.09% on a month on month basis, up 2.51% on a year-on-year basis.
45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than A588 Gr B HSLA steel plate quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.
