AH36 Mechanical Properties

Tensile Strength σ_b Mpa	Yield Point σ_s Mpa	Elongation or Extension Rate δ %	Impact Energy Absorption KV2 J
490~630	ReH: ≥355	≥21	0°C t≤50mm long.: ≥34 tr.: ≥24

• t-thickness；long.-longitudual，tr.-transverse；ReH-upper yield strength
• When the yield is not obvious, Rp0.2 can be measured instead of the upper yield strength.

① Test temperature 0°C, impact absorbed energy KV2:
◎ t＞50~70mm，long.: ≥41J，tr.: ≥27J
◎ t＞70~150mm，long.: ≥50J，tr.: ≥34J
