AISI 4140/41L40 - ANNEALED HR/CF (ALSO AVAILABLE IN DCF)

This medium carbon alloy grade is widely used for many general purpose parts requiring high tensile strength and toughness. 4140 contains chromium and molybdenum as alloying elements and may be heat treated over a wide range to give the combined advantages of proper hardness, strength and ductility. In conditions where localized hardness may be required, this steel is readily flame or induction hardened.

AISI 4140/4142- (MOD)

DCF(ALSO AVAILABLE IN HR)-MEDIUM CARBON ALLOY - PRE-HARDENED - (Cut From Plate)

4140/4142 is a fine pre-hardened alloy steel, ready for use and is machinable in its hardened state 260/321 Brinell.

AISI 6150 - ANNEALED HR/DCF

An electric furnace melt of chrome vanadium steel possessing the following characteristics: oil-hardening, high resistance to vibratory stress, standard deformation, medium hardness, high torque strength and bright polish.

AISI 8620/86L20

Carefully controlled proportions of chromium, nickel and molybdenum are responsible for the extensive use of 8620 as a carburizing alloy steel. Valuable features of this grade include extreme surface hardenability and internal strength.
