A516 Grade 70
A516 Grade 70
(OP)
Is there a suitable substitute for A516 Gr 70 steel to be used in low temperature (-44 F) applications? A516 Gr70 only comes in sheets, and I have some structural shapes (platforms and ladders) that need to perform under these low temps.

Regarding ladders, there are ASTM specifications for fabrication of ladders based on OSHA requirements.
Suggest you review
