SM490 h beam,sm400 h beam,s355jr h type beam steel materials exporting
In specification JIS G3106,there are SM490 h beam,sm400 h beam,in EN 10025-2 specification,there are s355jr H type Beam,S355J2+ar steel beam,they are all carbon structural H type steel beams.
JIS G 3106 SM490 h beam has three typies:
SM490A h beam
SM490B h beam
SM490C h beam
Above three typies of SM490 h beam have the same tensile strength and yield strength in mechanical property technicals,the main difference is the CARBON contain percentage requirement in chemical composition.
SM400 h beam,also comes from JIS G3106 specification,the same as SM490 h beam,but SM400 H beam has a lower tensile strength than SM490 H beam.
S355jr h type beam steel comes from EN 10025-2,DIN 1025.After done Normalized heat treatment,S355JR h beam normally write as S355JR+N h beam.S355JR+AR h beam means without heat treatment but only hot finished.
