Hot finish EN10210 S275J0H rectangular box sections RHS hollow section S275J2H

S275J0H and S275J2H rectangular hollow section steel (RHS) under EN10210 standard belong to low-alloy high-strength structural steel, and their heat treatment process and performance indicators must strictly comply with the standard requirements. The impact test temperature of S275J0H is 0℃, and the yield strength varies from 215-275MPa with thickness. It is usually delivered in hot-rolled or normalized (N) state to optimize the uniformity of the microstructure.

S275J2H hollow section maintains good impact toughness at -20 ℃, with a yield strength similar to J0 grade, but with stricter control of sulfur and phosphorus content (both ≤ 0.030%), making it suitable for structural components in low-temperature environments. Both types of steel require non-destructive testing according to EN10160 standard, with a wall thickness tolerance controlled within -10%.
