Typical Properties. AISI 4140 and 4150 is a medium carbon, chromium-molybdenum alloy steel. This steel is offered in a wide range of conditions including but not limited to: cold drawn annealed, hot roll heat treated, heat treated turned ground and polished.
4140 Alloy Steel Round is a cold drawn annealed steel of relatively high hardenability. Its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength.
Standard mill sizes for Alloy Steel 4140 Round Tube range from 2.375 OD X 0.375 Wall X 1.625 ID all the way up to 15 OD X 2 Wall X 11 ID. Other sizes may be available. Contact your local Metal Supermarkets store to confirm availability and pricing. Please note all items are subject to Continued
Alloy Steel Round Bar 4140 Annealed Cold Finish, also referred to as Chromoly Steel, is known for strength, resistance to fracturing, abrasion, and impact in high stress applications. 4140 is popular for a wide range of applications and is ductile and easily machined in the annealed state.
4140 Alloy Steel Flat is an cold drawn annealed steel of relatively high hardenability with its chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. 4140 Alloy Steel Flat responds well to heat-treatment and is relatively easy to machine in the annealed condition. 4140 Alloy , f1252 c mn property
