4130 Quenched R> 85/100 daN/mm¦
4130 Quenched R> 85/100 daN/mm¦
(OP)
Hi,
I have an Italian print that uses 4130, the problem I have is in the legend it calls out for: "Stato fornitura Mat- Bonificato R > 85/100 daN/mm²" when I Google it I come up with: State provision Mat- Quenched R> 85/100 daN/mm²
I know it has to do with the Tensile Strength of the material but can someone tell me exactly what it means?
Thanks

If you know this is the tensile strength range, than that would be your range. I am not sure if "R" designates ultimate tensile or yield strength.

"Stato fornitura mat-bonificato" means :
"supplied material condition : quenched"
( possibly Q+T, annealed , normalized - depending on shape of
steel )
85/100 daN/mm2 means : 850/1000 N/mm2
i.e. most possibly our Italian friends mean to say :
R(yield) > 850 N/mm2 / R(tensile) > 1000 N/mm2
Above values are in the range expected for steel material after heat treatment (quenching or....)
