0Cr15Ni5Cu2Ti martensitic precipitated hardened stainless steels with copper as the main strengthening element.Martensite precipitates hardened stainless steels with copper as the main hardening element, most commonly at [SCALE STEEL]17-4pH.0Cr15Ni5Cu2Ti can be seen on the basis of 17-4PH composition of reducing chromium and copper, nickel, and titanium instead of niobium steel, and 15-5PH is very similar.

The performance characteristics of：
0Cr15Ni5Cu2Ti steel has the following characteristics:
(1)High strength is obtained after aging hardening.
(2)The corrosion resistance is equal to 17-4PH.
(3)Good welding performance.
(4)Weak cold forming ability.
(5)Good thermal forming performance.
(6)Good cutting performance in both [SCALE STEEL]solid solution and aging state.
0Cr15Ni5Cu2Ti steel has good strength and toughness, good oxidation resistance at medium temperature, and good chemical stability in corrosive medium. It is usually used in the manufacture of important load-bearing [SCALE STEEL]components such as aero-engine combustion chamber casing and tapered beam installation edge.
