Low temperature grade S500QL steel plate and S550Q steel plate
Source:Xin Steel Industry Date:2021/09/08
Low temperature grade S500QL steel plate and S550Q steel plate supplies from european standard EN 10025-6 specification.In chemical composition,S500QL steel plate requires lower restriction for P % and S %. In Mechanical property,S550Q steel plate has a higher yield strength and tensile strength values.
S500QL steel plate done charp V-notch impact test at low temperature -40 ℃ with minimum values of impact energy in 30J on longitudinal.S550Q steel plate done charp V-notch impact test at low temperature -20 ℃ with minimum values of impact energy in 30J on longitudinal.For double quality guarantee,Xinsteel Industrial can offer EN 10204 3.2 mill certificates for these quenching and tempering S500QL steel plate and S550Q steel plate with SGS,ABS,TUV,LR,VL,BV,CCS.
