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.
