15-5 PH (1.4545 - 1.4548) stainless steel material, 1.4542 (630) is a more advanced and improved version of quality stainless steel material. The material, also called S15500, is a material developed for more special places where 630 quality materials are inadequate. 15-5 PH material has better mechanical and pure structure than 17-4 PH material. The microstructures of the UGIPURE15-5PH materials in the Mepa Metal stocks are purified by the slow pouring of the material during the second time casting and the roughness in the contents is minimized. In this way, 15-5 PH materials perform better than 17-4 PH material against both transverse and longitudinal forces.
Grading Quality Characteristics
Vulnerability to be beaten:
15-5 PH material is the most important and widely used area of the aviation industry. This stainless steel quality, which is produced in accordance with the high standards required in aviation parts, is used in almost every part, especially where very high mechanical value is desired. Aviation, as well as S15500 quality materials are the most commonly used. This quality material, which is also preferred in gear parts and working parts under pressure, is also used in fittings and bolts, especially because it has a homogeneous mechanical property.

Mechanical Properties at Room Temperature
15-5 PH (1.4545 - 1.4548) quality stainless steel is included in the group which can be cured by hardening. This material is a specially produced version of the 17-4 PH material, developed with double cast and aviation.
Other commonly used names of PH material are 1.4545, 1.4548, S15500, respectively. All 15-5 PH materials in Mepa Metal stocks correspond to all these quality names.
15-5 PH materials have very high mechanical strength. Mepa Metal 15-5 PH materials, which are both heat treated and double cast, have better mechanical properties than 630 (17-4 PH). In addition, the pure structure of UGIPURE 15-5 PH materials ensures a homogeneous mechanical properties at every point of the material.
15-5 PH quality stainless is not suitable for places where there is a high density.
15-5 PH quality stainless is magnetic and attracts magnet.
