[Abhishekmaitra]

Hi, can someone tell me the European standard for Carbon Steel, Alloy Steel, and Stainless Steel Nuts and Bolts for High Pressure or High Temperature Service?

Hi,
- Carbon steel: ISO 898
- Stainless steel: ISO 3506
- EN 1515 (specially part 4 if you have to fulfill PED)

Regards

Maybe the DIN (Germany)?
