17-4PH SUS630 1.4542 Stainless Steel Sheet And Coil Condition A
17-4PH is a martensitic precipitation hardening stainless steel.
17-4PH stainless provides an outstanding combination of high strength, good corrosion resistance,
good mechanical properties at temperatures up to 600°F (316°C), good toughness in both base metal
and welds, and shorttime, low-temperature heat treatments that minimize warpage and scaling.
17-4PH stainless is widely used in the aerospace, chemical, petrochemical, food processing,
paper and general metalworking industries.
| Grade | C | Si | Mn | P | S | Cr | Ni | Cu | Cb+Ta |
| 17-4PH, 630, S17400, EN 1.4542, DIN X5CrNiCuNb16-4, 0Cr17Ni4Cu4Nb | 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 |
17-4PH stainless grade combines the following characteristics:
- Good corrosion resistance (just below that of 304)
- High hardness and strength
- Controlled balance of mechanical properties by ageing (precipitation hardening)
- Improved toughness compared to 431 including use at sub-zero temperatures for the softer conditions
- Magnetic
- Thermal expansion comparable to carbon steel
- Easier to weld than martensitic grades like 420 and 431 stainless
17-4PH stainless 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 stainless is the natural choice of high strength, corrosion resistant steel particularly where standard
martensitic grades like 431 stainless aren’t quite good enough.
