Question: what is the difference between wcb and wcc material?
Answer: ASTM A216-WCC is also available ex stock and on an indent basis. ASTM A216 WCC has a slightly higher pressure/ temperature rating than A216 WCB as it has a higher yield strength and a slightly higher manganese content. ... A105 and WCB are compatible with A234 WPB fittings, and ASTM A106/API5LB line pipe.
