【Question】The valve body material is WCB – what type of material is this?
Thread Content
According to information found online, some say it is cast steel, while others say it is carbon steel. There are also those who classify steel based on its chemical composition: (1) Carbon steel: a. Low-carbon steel (C≤0.25%)； b. Medium carbon steel (C≤0.25~0.60%) ； c. High-carbon steel (C≤0.60%) Steel is classified by forming method: (1) Forged steel ； (2) Cast steel ； (3) Hot-rolled steel ； (4) Cold-drawn steel. The terms cast steel and carbon steel are simply different names used to classify steel. I would like to ask, what is the exact description for WCB material? Is it weldable?
WCB is carbon cast steel, with the standard designation ASTM A216; just look up the steel grade in the United States. W – weldable, C – cast, B – medium strength
It is cast steel, a type of welded structural steel per American standard A216; it can be welded.
Agree with what was said above; it’s ordinary carbon steel
What was said on the second floor is very correct and comprehensive.
It’s just ordinary carbon steel; in the American standard classification, it is considered a casting.
