Stainless Steel
1.4542 / 17-4PH
Stainless Steel 1.4542/17-4 PH is a corrosion-resistant, high-strength stainless steel. The presence of copper as an alloying element allows the material to be hardened through heat treatment and age hardening. Combined with good processability, this makes 17-4 PH an excellent choice for demanding, high-strength applications. It is widely used in aerospace, medical technology, and the energy and chemical industries.
