4320 Alloy Steel
Pennsylvania Steel Corporation offers an alternative to SAE 4320 alloy steel.
We produce FLEXOR® steel to provide similar, if not superior, chemical and mechanical properties to 4320 alloy steel. FLEXOR® is an excellent alternative material for many of the same applications as 4320 steel. These include applications that require high strength and high wear properties, coupled with machinability, such as Castings, Valves, Tool Holding Components, Work Holding Components, Machine Tool Parts, and Aircraft and Automotive 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 4320 alloy steel.
FLEXOR® has a higher core hardness, resulting in 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. In addition, FLEXOR® 4320 does not exhibit the work hardening that often takes place during machining with Nickel based steels, increasing its machinability.
The limitations and inferiority of 4320 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

Testimonials
"Just wanted to take a minute to say thanks. I always receive my orders on time and without any complications. I appreciate you keeping me so up to date on the order process through email, and the way the steel is cut and packaged so carefully. Using your Product (FLEXOR®) has increased standard tool life by as much as 25%-30%. Thank you again for all you hard work. I look forward to business with you again and again, it's always a pleasure!"
Testimonials
"Pennyslvania Steel Corporation has been a valued supplier for our company going on two decades. FLEXOR®'S versatility and reliability have been extremely helpful to the products we manufacture. Due to to FLEXOR®'S versatility at various hardness' we are able to use it at 28-32 HRC, 28-32 HRC and nitrided, or through hardened anywhere between 42 and 50 HRC. In our experience FLEXOR® has superior machinability to other comparable steel grades especially in higher hardness'. We machine FLEXOR® at 40 HRC and find this to be a key benefit to our manufacturing process."
