Superior Steel Alternative to

4135 Alloy Steel

Pennsylvania Steel Corporation offers an alternative to SAE 4135 alloy steel.

We produce FLEXOR® steel to provide similar, if not superior, chemical and chemistry properties to 4135 alloy steel. As a result, it can be used for many of the same applications as 4135 steel. Being a proprietary grade, Pennsylvania Steel insures that all FLEXOR® heats meet a high quality vacuum degas electric arc furnace melt process in order to insure cleanliness, grain refinement and maximum reduction ratios.

4135 Alloy Steel Alternative

FLEXOR®'s dependable quality and adaptability in heat treatment allows for a wide range of physical properties that are more appealing than those of typical ASTM, AISI or SAE 4135 alloy steel. FLEXOR® has a higher core hardness, resulting in a more uniform hardness through any cross section. The more uniform hardness and a fine grain microstructure produce a steel that is low weight with high fatigue and tensile strength and is an excellent material for applications that require a lighter weight component with the strength of steel.

FLEXOR® steel is available in a variety of sizes and conditions. These include, but are not limited to, decarb free alloys, hot rolled rounds, peeled steel bars, ground and polished rounds, hot rolled flats, hot rolled plates, turned forged round and billet.
