P355NH steel grade.

P355NH steel grade is a normalized, weldable fine grain steels for pressure purposed. The dimensions and tolerance on dimensions should be according to EN 10028-1.

 

P…N mean the room temperature, P…NH means the elevated temperature quality
P…NL1 means the low temperature quality, P…NL2 means the special low temperature quality.

 

Gangsteel is a large agent of HBIS wuyang mill in China and we are specialized in super thick steel plate. So, we could supply the min order is one steel plate and promise the competitive price in order to enlarge our oversea market.
