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.
