	PRODUCT DATA of 15-5PH H1025

Material	15-5PH H1025
Product Datasheet	AMI SMC AK Steel Bohler
General Information	15-5PH 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 Assembly	hardened above 552C (1025F)
Precautions	Parts should never be used in annealed condition.

General Corrosion Status	No specific corrosion protection required
Atmospheric Corrosion	The 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 Status	High Resistance to SCC: Table 1 Data Quality: Design Data
Machinability	The forming characteristics are good
Welding	Readily weldable by all commercial processes
