ExELL™ 15-5 PH Stainless Mold Steel
ExELL™ 15-5 PH was developed by Ellwood Specialty Steel as a premium quality mold steel. ExELL™ 15-5 PH is a martensitic precipitation hardening stainless steel with certain advantages over conventional stainless mold steels. Some of these characteristics include:
- Superior corrosion resistance
- Simple heat treatment
- Uniformity of mechanical properties
- Easy to weld
- Excellent polishability
- Good dimensional stability
- Very good toughness
ExELL™ 15-5 PH is used in various tooling and engineered parts. Some typical applications are:
- Injection molds for various plastics and rubbers
- Medical and food industry tooling
- Extrusion dies
- Compression molds
- Plastic processing equipment
- Manifold parts
- Glass molds
- Engineered components

HEAT TREATMENT (General Recommendations)
|Condition||Aging Temp||Hardness (HRC)|
Aging is performed by uniformly heating to the aging temperature, equalizing temperature from surface to center, holding 4 hours at temperature and air cooling. Slight shrinkage will occur after aging on the order of about 0.0005 to 0.0010 inches per inch.
Most aging is accomplished by using a 975°F age or higher. A 975°F aging treatment is used for a certain balance of hardness and toughness while higher temperature aging treatments will improve toughness and minimize over-aging if higher service temperatures are encountered.
|FEATURE Typical Hardness||P-20

*Machinability of P-20, Holder, 420F and 15-5PH is rated in the pre-hardened condition. S-7, H-13 and 420 are rated in the annealed condition. Overall ratings are 1-10 where 1 is the lowest rating.
