41xx steel - Wikipedia

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum , and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly , cro-moly , CrMo , CRMO , CR-MOLY , and similar).
