8630 Alloy Steel
Pennsylvania Steel Corporation offers an alternative to SAE 8630 Alloy steel.
FLEXOR® steel is produced to provide similar, if not superior, chemical, mechanical and performance properties to 8630 alloy steel. As a result, FLEXOR® can be used effectively for applications that require mild hardenability, weldability and ease of fabrication. These include oil drilling applications such as connectors, hangers, block valves, hydraulic lines and machine parts.
As 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 8630 alloy steel.
FLEXOR® has a higher core hardness than 8630 alloys, resulting in greater support if carburized, as well as less distortion through heat treatment. The more uniform hardness and a fine grain microstructure yield a higher fatigue and tensile strength, resulting in a steel that performs better in high stress applications than 8630 alloys. In addition, FLEXOR® utilizes its Chromium, Molybdenum and Tungsten Carbides to add significant wear resistance to the steel, increasing its life over 8630 alloys with similar Rockwell surface hardness.

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."
