Grade 17-4 PH plates valuable combination of high strength, good corrosion resistance and toughness in both base metals and welds gives Grade 17-4 PH plate designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs.
Grade 17-4 PH plate Hempel Special Metals are able to supply this grade in many of the conditions in the following forms :
Sheet/ Plate/ strip 0.2mm < 90mm
Bars 6.35mm Dia < 250mm Dia
| Grade | C | Cu | Mn | Ni | Nb-Cb | Cr | Nb-Ta | P | Si | S | Fe | |
| 17-4 PH | min. | – | 3.0 | – | 3.0 | 0.15 | 15 | 0.15 | – | – | – | – |
| max. | 0.070 | 5.0 | 1.0 | 5.0 | 0.45 | 17.5 | 0.45 | 0.040 | 1.0 | 0.030 | 73 |
High strength is maintained to approximately 600F (316C). This material has good resistance to stress corrosion cracking in the lower strength conditions.
