Under the specification EN 10025-2, S275J2 plates are mainly used in the building industry and mechanical engineering, containers,storage tanks and roll formed steel profiles,such as steel angles, steel structures, H-beams, T-sections. For A572 grade 42 CS steel carbon plate, S275J2 carbon steel, our engineers still suggest done normalized heat treatment for them if customers want to improve their steel's property when using. Else, this steel must be done low temperature impacting test at -20℃.
Compared with A572 grade 42 CS steel carbon plate, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while A572 grade 42 CS steel carbon plate is not.
Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < A572 grade 42 CS steel carbon plate 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 A572 grade 42 CS steel carbon plate product packaging.
