15-5PH
15-5PH stainless steel, also known as precipitation hardening stainless steel, is a martensitic
precipitation hardening stainless steel, with good processability, excellent mechanical properties,
resistance to general corrosive environments, good strength, toughness and ductility, hardness and
corrosion resistance. The same as 304 stainless steel it is good. 15-5PH may be used to treat or heat
treat conditions to obtain various properties. Machining can be carried out under a variety of
achievable conditions, however the H1150M has the best service life in this condition. Applications:
Aerospace, aircraft parts, components manufacturing high pressure valves and other corrosive
environments, grooves, fasteners, equipment and equipment. ●15-5PH chemical composition①:
Carbon C: ≤0.07 Manganese Mn: ≤1.00 Silicon Si: ≤1.00 Chromium Cr: 14.0~15.5 Nickel Ni②:
3.5~5.5 Phosphorus P: ≤0.04 Sulfur S: ≤0.03 Copper Cu: 2.5~4.5 Niobium+Tantalum Nb+Ta:
0.15~0.45 Note: ①A single value is the highest value unless otherwise specified; ②When used in
some pipe-making processes, the nickel content of some types of austenitic stainless steel must be
slightly higher than the value shown in the table.
