General Characteristics – Alloy Steel AISI 8640. Alloy steel 8640 is a low-alloy steel containing nickel, chromium and molybdenum as alloying elements.
This is a nickel-chrome-molybdenum steel with excellent hardenability, strength and toughness.
This is a low-carbon chromium-bearing, case-hardening alloy steel used where as forged camshafts and gears, gear shafts, bushings and connecting rods.
AISI 4135 grade alloy steel is forged at a temperature of around 2200oF (1205oC) and could be forged down to a temperature of approximately 1700oF (925oC).
AISI 4330V steel stockholders and suppliers, delivering to the whole of the UK. AISI 4330V is a nickel chromium molybdenum vanadium alloy steel specification
