An unalloyed carbon steel with good workability and moderate mechanical characteristics. Used for mechanical components subject to moderate stress, it is well suited to cold working applications like forging

A chrome alloy steel, hardenable, with good tensile strength and tenacity. Used for shafts, gears, pivot pins and part subject to dynamic loads. Suited to heat treatments like hardening/tempering and hardening.

A boron-chrome steel with excellent hardenability and good resistance to wear. Ideal for highly stressed mechanical components like springs, bars and transmission components.

A chrome alloy steel with good hardenability and tensile strength. Used for shafts, bushings and parts subject to moderate wear. Can be heat treated to improve its surface hardness.

A chrome alloy steel with characteristics similar to 34Cr4 but with a higher carbon content, which improves its tensile strength. Used in general purpose mechanical applications and components subjected to torsional loads.

A boron-chrome steel with excellent hardenability and good workability. Ideal for fabricating cold forged or drawn components like fasteners and high tensile strength pivot pins.

A chrome-molybdenum-boron steel with very high tensile strength and excellent hardenability. Used for critical applications which demand excellent mechanical specifications and resistance to wear.

A chrome alloy steel with good hardenability and resistance to fatigue. Used for engine shafts, gears and parts subject to cyclic loading. Its mechanical properties can be improved by hardening and tempering.

A carbon steel alloyed with boron to improve its hardenability. Used for mechanical components subject to heavy loads like axles, tie-rods and transmission components.
