Alternative Alloy Steel Case Studies

In recent tests FLEXOR® has been compared to 4330V for high torsional loading and wear resistance in the Oil and Gas Drilling Industry. FLEXOR has proven to have high toughness even in elevated hardness (40+HRC). In a typical mud motor previous drive shafts were known to have abrupt failures causing down and additional tooling issues. The FLEXOR drive shaft bent and kept performing until it was discovered on a routine maintenance evaluation.

In the closed die forging business a tough supportive wear resistant bolster in required to support the millions of cycles and excessive cyclic tonnage loads. FLEXOR has been unsurpassed in the carburized condition at withstanding heavy loads and wear resistance.

The Performance Racing Industry is finding FLEXOR to be an excellent alternative to other higher alloy more costly alloys such as 300M and 9310. FLEXOR has been used in transmission components by many well known manufacturers where toughness and strength are paramount.

"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 hardnesses 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 hardnesses.  We machine FLEXOR at 40 HRC and find this to be a key benefit to our manufacturing process.
