Principal Design Features
|
|
This is a nitrogen strengthened, low nickel austenitic stainless steel. It is characterized by high strength (double that of 304 stainless), excellent corrosion resistance and fabricability.
|
|
|
Applications
|
|
It is widely found in a variety of fasteners, shafting and communication hardware.
|
|
|
Machinability
|
|
Slow speeds, positive feeds and abundant resulphurized lubricant are essential to success in machining this alloy. Speeds and feeds similar to those employed with 316 or 317 stainless are appropriate here. All common machining practices can be used on this material. Chips will be tough and stringy and it is recommended that curlers or breakers are used.
|
|
|
Forming
|
|
All common forming techniques can be used with this alloy. Springback will be greater than with standard austenitics and should be taken into consideration when choosing the appropriate forming forces. Process annealing is recommended to remove stresses resulting from this alloys' high work hardening rate. Heat to 1950 F(1065 C) for intermediate anneal.
|
|
|
Welding
|
|
Pre-heating is not required with this material and all common welding methods including gas tungsten arc, gas metal arc and submerged arc are acceptable. Filler metal selection should be of similar chemistry for maximum strength and resistance to intergranular attack.
|
|
|
Forging
|
|
Heat to 2000 F, soak to equalize, then heat to 2150 and equalize prior to forging.
|
|
|
Annealing
|
|
Soak at 1900-2050 F, quench quickly in air or water.
|
|
|
Hardening
|
|
Hardening this alloy requires cold working. It will not harden with exposure to thermal treatment.
