4140 Steel Plate

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 steel plate. 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. General information on 4140 4140 alloy steel is a low alloy steel that contains chromium molybdenum and manganese. Our inventory also now features pre blasted abs plates. 4140 alloy steel flat responds well to heat treatment and is relatively easy to machine in the annealed condition.

4140 alloy steel flat has good strength and wear resistance. When our phone rings with 4140 plate inquiries many customers also tell us they are overwhelmed with supply chain complexity. 4140 as rolled plate is a chromium molybdenun alloy steel that can be oil hardened to relatively high hardenability. Versatile structural quality steel plate that offers greater wear resistance than lower carbon grades of steel.

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 also has high fatigue strength excellent strength to weight ratio abrasion and impact resistance and torsional strength. At delaware valley steel we also feature a36 1045 plate 4140 plate and many others. Alloying elements and thermal treatments such as quenching and tempering greatly influence the hardness and strength of the steel.

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. Available in grade 4140 in both standard under 3 inches and heavy 3 inches or greater plate thicknesses. The chromium content provides good hardness penetration and the molybdenum imparts uniformity of hardness and high strength. Because it contains chromium and molybdenum it is sometimes referred to as chromoly steel.
