The Full Form of CRCA is Cold rolled close annealed.
CRCA is an abbreviation of “cold rolled close anneal”. This is a steel grade in which cold rolling is done after hot rolling and pickling, to reduce the thickness of steel. Cold rolling makes the material hard. This cold rolled steel is then annealed in a closed container where nitrogen or any other non-oxidizing gases softens it for use and also guards it against oxidation.
