FLEXOR® Superior Steel Alternative to

4150 Alloy Steel

We produce FLEXOR® steel to provide similar, if not superior, chemical and mechanical properties to 4150 alloy steel. As a result, FLEXOR® can be used as an alternative material for many of the same applications as 4150 steel. These include applications that require a high wear resistance, high resistance to impact and toughness, such as Aircraft and Aerospace Components, Automotive Components, Structural Tubing, Brakes, Clutch and Flywheel Components.

Being a proprietary grade, Pennsylvania Steel ensures that all FLEXOR® heats meet a high quality vacuum degas electric arc furnace melt process in order to ensure cleanliness, grain refinement and maximum reduction ratios.

FLEXOR® Properties

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 4150 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.

The limitations and inferiority of 4150 alloy steel can be frustrating and jeopardize the success of your project or application.

FLEXOR® Sizes & Conditions

FLEXOR® steel is available in a variety of sizes and conditions. These include, but are not limited to:

  • Decarb free alloys
  • Hot rolled flats
  • Hot rolled rounds
  • Hot rolled plates
  • Peeled steel bars
  • Turned forged rounds and billet
  • Ground and polished rounds
