15-5PH Stainless Steel Sheet UNS S15500 Cold Rolled Steel Strip
15-5PH precipitation hardening stainless steel (UNS S15500) is a variant of the 17-4PH (S17400)
chromium-nickel-copper precipitation hardening stainless steel.
Both alloys exhibit high strength and moderate corrosion resistance.
High strength is maintained to approximately 600°F (316°C).
This alloy is designated Grade or Type XM-12 in several specifications.
| Grade | C | Si | Mn | P | S | Cr | Ni | Nb | Cu |
| 15-5PH | 0.04 | 0.5 | 0.75 | 0.020 | 0.005 | 14.5 | 4.8 | 0.3 | 3.5 |
The 15-5PH stainless alloy was designed to have greater toughness than S17400,
especially in the through-thickness (short transverse) direction.
This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape.
The composition and processing of ATI 15-5™ alloy is carefully controlled to minimize its content of delta ferrite,
which is present in the S17400 material.
The S15500 alloy is martensitic in structure in the annealed condition and is further strengthened by a
relatively low temperature heat treatment, which precipitates a copper containing phase in the alloy.
Like the S17400 alloy, the S15500 alloy requires only a simple heat treatment;
a one-step process conducted at a temperature in the range 900°F (482°C) to 1150°F (621°C)
depending on the combination of strength and toughness desired.
A wide range of properties can be produced by this one-step heat treatment.
Heat treatment in the 900°F (482°C) range produces the highest strength,
although it is slightly less than those of semi-austenitic alloys like S17700 or S15700.
The latter precipitation hardening stainless steels generally require more steps to complete heat treatment.
The 15-5PH stainless steel is generally better suited for plate applications than are the semi-austenitic alloys.
PRODUCT FORMS
