Principal Design Features		This is a "super austenitic" stainless designed for resistance to phosphoric and sulfuric acids and seawater.
Applications		Applications include tubulars for downhole deep corrosive wells, pollution control, radiation waste systems, chemical handling equipment, valves pumps and piping.
Machinability		Conventional machining techniques used for iron based alloys may be used. Machining characteristics are somewhat similar to those for the austenitic (300 Series) stainless steels. This alloy does work-harden during machining and has higher strength and "gumminess" not typical of steels. Heavy duty machining equipment and tooling should be used to minimize chatter or work-hardening of the alloy ahead of the cutting. Most any commercial coolant may be used in the machining operations. Water-base coolants are preferred for high speed operations such as turning, grinding, or milling. Heavy-duty lubricants work best for drilling, tapping, broaching or boring. Rigid mounting of tooling and the workpiece are important to avoid "chatter".
