High Strength Steels

Kromite® Cold Drawn

4140 (mod), Cold Finished, Annealed Alloy

Kromite CD is a modified 4140 alloy.  It is offered in the cold finished annealed condition. Typical hardness is 180/235 BHN.  Typical tensile strength 114,000 PSI.  Its wear resistant properties far exceed that of “cold roll” steels.  It is easy to machine and will accept additional heat treatment.  It is considered an excellent upgrade in applications where commercial alloy and carbon steels including AISI 4140, 1018, 1045 and 1060 are utilized.  Associated Steel has an extensive inventory of alloy shapes available for immediate shipment.

Kromite CD is an excellent high strength steel for all forms of transfer and various guide rails in the automotive, food processing (beef and pork slaughter operations), major appliance and material handling industries.  Call or email us for a quote.
