General characteristics of Alloy Steel 94B30
This alloy, a nickel-chromium-molybdenum grade, contains a very small amount of boron, which has a marked effect on its hardenability.
This grade shows good strength and toughness properties and very good hardenability, this latter as a result of the boron addition. The alloy is used in applications such as forged connecting rods, engine bolts and studs.
This alloy would be forged at a temperature in the region of 2200ºF to 1700ºF (1205 to 925ºC.)
Annealing:This alloy may be annealed for optimum machinability to a structure of coarse pearlite with minimum ferrite. The alloy would be annealed at a temperature of 1450 – 1550ºF (790 – 845ºC) followed by furnace cooling.
Normalizing: A temperature in the region of 1650ºF (900ºC) is used in normalizing of this alloy, followed by air cooling.
Hardening: This alloy would be austenitized at 1550 – 1625ºF (845 – 885ºC) and oil quenched or air cooled, depending upon size and complexity of part.
Tempering: The alloy would be tempered at a temperature based on past experience, to give the required mechanical properties.
Machinability : This alloy is readily machined following appropriate heat treatment.
Weldability: The alloy is readily welded by all normal fusion methods, but only in the annealed or normalized conditions, prior to case hardening.
