Because it contains chromium and molybdenum it is sometimes referred to as chromoly steel. Over the past 60 years delaware valley steel has evolved into one of the northeast s and mid atlantic s premier suppliers and processors of a variety of carbon and alloy steel plate.

4140 material is low alloy steel with the presence of chromium molybdenum and manganese which is specifically tailored for applications where strength hardness and impact resistance are critical. Castle metals stocks a wide range of alloy 4140 plate distributed globally from our distribution centers in the u s canada mexico u k singapore and shanghai. At delaware valley steel we also feature a36 1045 plate 4140 plate and many others. Where it makes sense castle metals can simplify our customers.

Versatile structural quality steel plate that offers greater wear resistance than lower carbon grades of steel. Universal steel stocks 4140 from thick up to 12 thick in multiple finished conditions including as rolled annealed and pre hard. Alloying elements and thermal treatments such as quenching and tempering greatly influence the hardness and strength of the steel. 4140 as rolled plate is a chromium molybdenun alloy steel that can be oil hardened to relatively high hardenability.

4140 alloy steel flat responds well to heat treatment and is relatively easy to machine in the annealed condition. The chromium content provides good hardness penetration and the molybdenum imparts uniformity of hardness and high strength. When our phone rings with 4140 plate inquiries many customers also tell us they are overwhelmed with supply chain complexity. 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.
