Pressure vessel steel
A106-C pressure vessel steel
A106 Grade C is the higher strength class of the seamless ASME carbon steel pipe.
- Delivery conditions
- +N / +NT
- Also known as
- A/SA-106 Gr. C, SA106-C, A106C
Designations
- EN standard
- A/SA-106 Gr. C
- Group
- Pressure vessel steel
What it is used for
Heavier ASME pipe where Grade B results in too thick a wall.
Limits
A106-B when B is enough. P355NH when EN 10028 governs the plate.
Delivery
We source A106-C from European mill partners as plate, flat bar, round bar, seamless tube, welded tube, cut to your dimensions and ship the certificate with the material. Typical condition: +N / +NT. Standard: A/SA-106 Gr. C. From a single cut piece to larger lots — with no minimum charge, so you do not have to buy a full commercial length to get what you need.
Certificates and documentation
A106-C can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. On pressure-bearing material the certificate is part of the product: standard, condition and tests must be on the enquiry, and 3.2 must be agreed before the material is locked at the mill. EN 10204 3.1 can be supplied on a wide range of our materials — 3.2 and third party by project, when the mill can issue it.
