A Study of Micro-cracks in Overheated Forgings of Ultra
AMS 6414H (AISI 4340) vacuum arc remelted steels with ultra-low sulfur content of less than 0.001%. The investigation revealed that the crankshafts broke because small cracks created in the forging process became large when the crankshafts were subjected to expected operating loads in aircraft engines. The small cracks were caused by incipient

O1 Tool Steel. O1 Tool Steel is the original oil-hardening, “non-shrinking” tool steel that can be hardened to the Rockwell C 65 range from a low austenitizing temperature. O1 is a general-purpose tool steel that is typically used in applications where alloy steels cannot provide sufficient hardness, strength, and wear resistance.
AISI 1040 equivalent to EN8/080M40. An unalloyed medium carbon steel. AISI 1040 is a medium strength steel with good tensile strength. Suitable for shafts, stressed pins, studs, keys etc. 1040 must be pre-heated to 300 to 500 degrees F before welding and reheated to between 1100 degrees F and 1200 degrees F after welding.

Heating for forging of oil tool steel O1 must be done slowly and uniformly. Forging of alloy O1 steels can be performed at 980-1000°C, and reheat as often as necessary. But not forge below 800°C. After forging AISI O1 tool steel, cool slowly in lime, mica, dry ashes or furnace. ASTM O-1 tool steels should always be annealed after forging.
