Pennsylvania Steel Corporation presents an alternative to SAE 4140 alloy steel.
FLEXOR®'s chemistry and mechanical properties are comparable, if not superior to 4140 alloy steel and thusly, can be utilized in most of the same applications. 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 reductions.
FLEXOR®'s consistent quality and versatility in heat treatment allows for a wide range of physical properties that are more appealing than those of typical ASTM, AISI or SAE 4140 alloy steel. Higher core hardness 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 bars, hot rolled plates, turned forged rounds and billet.
|4140||(x1000 kg/m3) 7.7 - 8.03 @25°C|
|FLEXOR®||7.543g/cm3 per ASTM B311|
|4140||(J/kg-K) 473 @150 - 200°C|
The limitations and inferiority of 4140 alloy steel can be frustrating and jeopardize the success of your
project or application.
