Pennsylvania Steel Corporation offers an alternative to SAE 4130 alloy steel.
We produce FLEXOR® steel to be similar if not superior in its chemical and chemistry properties to 4130 steel. Taking this into account, it is suitable and can be utilized in most of the same applications as 4130 alloy steel: Automotive, Oil and Gas Drilling, Forging, Warm and Cold Forming, Performance racing, Powdered Metal, Die Casting, Machine Building, Tool Making, Work-holding, Transfer Systems, among many others. Being a proprietary grade, Pennsylvania Steel insures that all Flexor® heats meet the high quality, vacuum degas electric arc furnace melt process in order to insure cleanliness, grain refinement and maximum reduction ratios.
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 4130 alloy steel. Flexor® has a higher core hardness which typically means a more uniform hardness through any cross section. The more uniform the hardness along with a fine grain microstructure yields a higher fatigue and tensile strength for difficult applications. Please compare total percentage of alloy below.
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 rounds and billet.
