Forged A105 versus cast WCB
ASTM A105 describes a forged product specification. ASTM A216 WCB describes a casting material. A buyer requesting forged A105 should not automatically receive a WCB casting as an equivalent.
Where it fits in a ball valve RFQ
Define whether the valve is floating or trunnion mounted, the nominal bore, pressure class, full/reduced port, pressure-temperature requirements, ends, trim and seat type.
Related grade terminology
A105N often indicates an A105 material supplied in a normalized condition, where applicable. Heat treatment and documentation must match the actual purchase specification.
What to confirm
For project orders, request applicable material certificates, supplementary impact tests if required, sour-service requirements where relevant and traceability.
Frequently asked questions
Does A105 specify the ball and seat material?
No. A105 usually identifies a carbon steel body or other pressure-containing forged component; ball, stem and seat materials must be defined separately.
Can I order A105 as a cast steel body?
A105 refers to forging; use the appropriate casting specification for a cast body.
