Structural EN10083-3 alloy steel good machining property
The difference between Q235 steel and Q345 steel:The lower limit of yield strength of Q235 steel is 235MPa, the lower limit of yield strength of Q345 steel is 345MPa. The EN10083-3 alloy steel alloy content of Q235 steel is common carbon steel and Q345 steel is low alloy steel. Q345 steel is used for structures, mechanical parts, building structures, general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, EN10083-3 alloy steel mining machinery, power stations, bridges, etc..
We have 4 typical production lines EN10083-3 alloy steel, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < EN10083-3 alloy steel steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished EN10083-3 alloy steel product packaging.
