Stainless Steel 15-7

Chemistry Data

General Information

Principal Design Features

This alloy is a semi-austenitic precipitation hardening stainless steel. It combines moderate corrosion resistance with high strength and hardness at operating temperatures up to 900 F.

Applications

Retaining rings, springs, diaphragms, aircraft bulkheads, welded and brazed honeycomb panels and other uses requiring high strength at elevated temperatures.

Machinability

Tough and gummy, this alloy responds best to machining in the hardened conditions. Chip breakers are suggested.

Corrosion Resistance

Like many of the precipitation hardening grades, 15-7 will display rust in marine environments. It is best suited to exposure to dilute acids and alkalis, fresh water and atmosphere. For optimum performance, material must be clean and free of scale and im

Welding

Readily welded by most of the common arc and resistance methods. Preheating and post weld annealing is not required in this alloy. Avoid inert gas shielding to prevent oxidation of aluminum.

Heat Treatment

CONDITION C - Results from heavy cold working of solution treated material. CONDITION CH900- Heat Condition C material to 900 F(482 C), hold for 1 hour, air cool. CONDITION A1750- After fabrication heat solution treated material to 1750 F(955 C), hold for

Hot Working

This alloy works well in all common hot working procedures. Material should be annealed after hot working for best heat treat response.

Cold Working

Cold work is restricted only by this alloys high initial yield strength. The alloy is not favored for cold working but can be moderately formed.

Annealing

1900 F (1038 C) for 1 hour, rapid cooling. Also known as " solution treating."
