500N (AS/NZS 4671) / Equivalents
Is it really 500N (AS/NZS 4671)? 1 “equivalents” checked
Cross-reference tables pair grades by name and history. Here each pairing is judged on the minimum values each standard guarantees, with the sources for both sides.
Same strength class; guaranteed values agree within a few MPa. Still check thickness bands and impact quality.
B500BBSI
Same class of steel, but at least one guaranteed value is lower or tested differently. Recheck the design.
Commonly listed as an equivalent, but the guaranteed values do not support substitution.
