SUS630 Stainless Steel Sheets 17-4PH Plate
17-4PH steel is a precipitation hardening martensitic stainless steel ( UNS S17400 ), a wide range of
mechanical properities is available via simple aging within a 482~621℃ temperature range.
Chemical composition typical value %
| Grade | C | Si | Mn | P | S | Cr | Ni | Nb | Cu |

17-4PH chromium-nickel-copper precipitation hardening stainless steel used for applications requiring
high strength and a moderate level of corrosion resistance.
High strength is maintained to approximately 600°F (316°C).
The S17400 alloy is martensitic in structure in the annealed condition and is further strengthened by a
low temperature treatment which precipitates a copper containing phase in the alloy.
In comparison to many alloys in the precipitation hardening family, the S17400 alloy requires a simple
heat treatment; a one step process conducted at a temperature in the range 900°F (482°C) to 1150°F (621°C)
depending on the combination of strength and toughness desired.
A wide range of properties can be produced by this one step heat treatment.
Heat treatment in the 900°F (482°C) range produces highest strength, although slightly less than that
of alloys like S17700 or S15700.
The latter precipitation hardening stainless steels generally require more steps to complete heat treatment.
PRODUCT FORMS
