Material Description
15-5PH, is a martensitic precipitation strengthened stainless steel, with exceptional room temperature strength and good mechanical properties up to 300°C (572°F). This kind of steel is characterized by having good corrosion resistance and excellent mechanical properties, especially in the precipitation hardened state. This type of steel is widely used in variety of engineering applications requiring high hardness, strength and corrosion resistance. This material is ideal for many part-building applications (Direct Part) such as functional metal prototypes, small series products, individualized products or spare parts. Using standard parameters, the mechanical properties are fairly uniform in all directions.
Material Properties High hardness and strength High corrosion resistance Can be highly polished | Applications General engineering, including functional prototypes, small series products, individualized products or spare parts. Aerospace, petrochemical and food processing, like Parts requiring high corrosion resistance, sterilisability, etc., and parts requiring particularly high hardness and strength. |
