1 AMS 5643 (17/4 PH)Technical DatasheetService. Quality. ApplicationsMachinabilityUsed where high strength and good corrosion resistanceare required as well as for applications requiring highfatigue strength, good resistance to galling and stresscorrosion resistance. It is suitable for intricate partsrequiringmachining and welding and where freedom fordistortion is a requirement. Used in aerospace, defenceand offshore oil & gas industries. For missile components,motor shafts, valve stems, gears and other DescriptionAn American aerospace grade stainless steel that contains4% copper and may be hardened by a single low-temperature precipitation hardening heat treatment,producing excellent mechanical properties at a :Can be supplied in the annealed condition (Condition A) orheat treated as follows.

2 -Condition H900 (900 F) Condition H925 (925 F)Condition H1025 (1025 F) Condition H1075 (1075 F)Condition H1100 (1100 F) Condition H1150 (1150 F)The material should not be used in the annealed grade of stainless steel has a typical density and can be annealed condition surface cutting speed of 80 ft/minanda machinability rating of 50% of B-112 rated at 100%.Over-aged condition, 130 ft/min and 75% of B-1112 ratedat 100%.Precipitation Hardening Stainless Steel BarCorrosion ResistanceSuperior to straight chromium grades like 410,approaching corrosion resistance of the chromium many corrosive media it is equal to such gradesas302.
