Steel
Steel 9310
Aging Procedure
Not applicable to this alloy.
Annealing Procedure
Anneal at 1575 F and slow furnace cool.
Cold Workability
The alloy has good ductility even in the hardened and tempered condition. It can be cold worked by conventional methods as used on the other low alloy steels.
Forgeability
Forge at 2175 F down to 1700 F.
Formability
The alloy has good ductility even in the quenched and tempered condition. Thus it may be readily formed by conventional methods.
Hardening Procedure
The alloy will harden due to cold working or by thermal treatment and oil quenching. See "Heat Treatment".
Heat Treatability
Typical heat treatment for carburizing is to heat at 1700 F in the carburizing environment, followed by an oil quench. The alloy may then be normalized at 1650 F, air cooled, and tempered at 300 F for good core mechanical properties on the order of 170 ksi tensile strength.
Hot Workability
No data given - contact the alloy supplier.
Machinability
The alloy machines by conventional means as with the other low alloy steels. It is best to machine 9310 while it is in the normalized or tempered condition.
Principle Design Features
AISI 9310 is a low alloy steel containing nickel, chromium and molybdenum noted for its good hardenability with high impact and fatigue strength. It is often used for carburized case hardened parts.
Tempering Procedure
The usual tempering temperature for optimum properties is 300 F.
Weldability
Weldability by standard process, using established weld procedures, is good.
