Principal Design Features
|
|
This alloy was designed primarily to combine the strength and corrosion resistance of an austenitic stainless steel with superior wet abrasion resistance.
|
|
|
Applications
|
|
Considered a long term cost effective alternative to wear and abrasion resistant materials. Structural components in a variety of transportation equipment, hose clamps, fasteners, sewage plant structures and bulk solids handling equipment are among the most common applications.
|
|
|
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
|
|
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.
|
|
|
Welding
|
|
This alloy is an austenitic, nitrogen strengthened steel combining corrosion resistance comparable with 316 stainless and greater strength. It is readily fabricated and remains non-magnetic even after severe forming operations.
|
|
|
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.
