SUS630 Stainless Steel Cold Rolled Coil UNS S17400 ASTM A693 17-4PH
Strip
Grade 17Cr-4Ni-4Cu-0.2Nb, 17-4 PH (1.4542) is the most common example of the
precipitation hardening stainless grades.
Type 630 stainless alloy combines good corrosion resistance
with high strength and good impact toughness.
C | Si | Mn | P | S | Cr | Ni | Cu | Nb |
0.07 max | 1.00 max | 1.00 max | 0.040 max | 0.030 max | 15.00~17.50 | 3.00~5.00 | 3.00~5.00 | 0.15~0.45 |
The 17-4PH grade combines the following characteristics:
17-4PH develops its high strength from the precipitation of copper
particles in its martensitic matrix.
It comes in various conditions denoted by H plus ageing temperature
in °F, for example H900, H1025 etc.
The higher the ageing temperature, the lower is the strength and
the higher are the ductility and toughness.
The minimum 0.2% PS varies from 520 MPa to 1170 MPa depending on
the condition.
The combination of high strength and good corrosion resistance
finds uses in:
Drive shafts, bearings, gears, hydraulic rams, valve stems, load
cells, bridge bearings, tensioning systems,
golf clubs, quick release pins, fasteners, aerospace, medical devices, food processing, conveying equipment,
fall arrest systems
17-4PH is the natural choice of high strength, corrosion resistant steel particularly where standard
martensitic grades like 431 aren’t quite good enough.
