Bohler
General Information15-5PH is a precipitation-hardening, martensitic stainless steel used for parts requiring corrosion resistance and high strength at temperatures up to 315C. Alloy 15-5PH has good transverse ductility and strength in large section sizes. This material is supplied in either the annealed or overaged condition and is heat treated after fabrication
Processing and Assemblycold worked and aged at 480C
PrecautionsParts should never be used in annealed condition.

RELEVANT PROPERTIES FOR USE IN SPACE COMMUNITY
General Corrosion StatusNo specific corrosion protection required
Atmospheric CorrosionThe general level of corrosion resistance exceeds that of Types 410 and 431, and is approximately equal to that of 17-4 PH Stainless Steel The general level of corrosion resistance is best in the fully hardened condition, and decreases slightly as the aging temperature is increased.
Stress Corrosion StatusModerate Resistance to SCC: Table 2
Remark: Requires Stress corrosion evaluation form
Data Quality: Design Data
MachinabilityThe forming characteristics are good
WeldingCan be welded using TIG or eletric arc welding process, but should be performed in annealed condition
