WebLow alloy steel with addition of nickel, chromium and molybdenum with high strength and impact properties. Steel containing 0.2-0.3% molybdenum and 1.65-3.75% nickel as alloying elements with case hardening properties. Nickel and chromium added alloy steel with toughness, resistance to oxidation and corrosion. 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). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded, requirin…
