"Is grade 60 rebar hardenable?
Grades 60, 80, and 100 are equivalent to roughly 1045, 1060, and 1070 and can be hardened. That's why you're not supposed to weld rebar for construction purposes, it makes a heat-affected zone (HAZ) that leaves a brittle spot and voids the specs.Oct 19, 2019 ...." off google, i've been excited about the newer full fiberglass rebar , maybe slightly cheaper but it's not about the rebar it's a friggin solid 1/2" and +/- sizes in fiberglass rod like a new type plank all together , many uses probably , and the rebar being similar the "10xx" whatever not really accurate on the alloy side most likely it's a little more rust resitant when it takes a spring temper for example and gets coated with grease and sealed into pex for eaxmple then clamped threough stuff or used all metal and insulation for fireresistance etc....
