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
