What is chemical composition of nm400 steel specifications

EN10025-3 S275N steel is a normalized or normalized rolled weldable fine grain structural steel grade. S275N plates shall be under normalized delivery condition and be done low temperature impacting test at -20℃when rolling. If customers request the limited for some chemical compositions, such as P and S,our mill also can satisfy this strict request when processing owning to our highest technical. For the available thickness, NM400 steel specifications, S275N plate is supplied up to 250mm.

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 annual capacity is 200 thousand tons.

As the thickness and hardness of increase, the tendency to crack at the cutting edge increases. In order to prevent the NM400 steel specifications from cutting cracks, preheating should be carried out before cutting. Special attention should be paid to preheating to make the entire NM400 steel specifications interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole cannot be preheated, the partial preheating method can be used instead.
