Stainless Steel 17-4 PH polished optical mirrors
Superpolished Stainless Steel Optics and Mirrors
Superpolished metal surfaces approaching 5 Angstrom Ra finish, without using polished electroless nickel plating are now possible for use as mirrors. Valley's process of optically polishing these pure metal substrates and wafers enables materials such as 304SS, 316SS, 430SS and 17-4 PH (Custom 630) Stainless Steel, to be used as mirrors.
Physical properties of 17-4 PH Stainless Steel which are important for critical applications include:
