Alloy Steel for Metal Forming & Bending
FLEXOR® is a proprietary alloy steel for metal forming and bending developed by Pennsylvania Steel Corporation. Unlike standard alloy steels or tool steels, FLEXOR® is engineered with a unique chemistry that offers exceptional hardness, machinability, and wear resistance. This steel has become a trusted choice for industries requiring high-strength, durable materials that withstand demanding metal forming processes.
FLEXOR® is highly versatile in heat treatment, allowing manufacturers to achieve a wide range of physical properties, including:
- Higher core hardness – Ensures uniform strength across the cross-section
- Superior machinability – Especially at higher hardness levels
- Dual properties when case hardened – Combining surface hardness & core toughness
Its fine-grain microstructure enhances fatigue and tensile strength, making FLEXOR® an ideal solution for precision forming, machining, and bending applications in metalworking, oil & gas, and advanced manufacturing.
FLEXOR® Alloy Composition
- Chromium (0.85%) – Enhances hardness & wear resistance
- Molybdenum (0.5%) – Improves toughness & high-temperature strength
- Tungsten (0.5%) – Provides abrasion resistance
- Carbon (0.34%) – Strengthens the steel matrix
- Nickel (0.1%) – Enhances ductility
- Manganese (0.8%) – Improves toughness
- Silicon (0.3%) – Increases hardenability
- Sulfur (0.015%) – Aids machinability
FLEXOR® is the only CrMoW steel readily available for oil & gas, precision metal forming, and high-performance machining. Its dense material structure and thermal conductivity provide superior fatigue and impact resistance, making it well-suited for mud motor drive shafts, hydraulic shafts, mandrels, drilling bits, and downhole tools.
Industry Applications – Metal Forming & More
FLEXOR® is a preferred material in metal forming & bending due to its strength, toughness, and wear resistance. It is used in:
