17-4PH H1150 Solid Bar Stainless Steel Round Bars UNS S17400 ASTM A564 Standard
The 17-4PH H1150 is corrosion resistant stainless steel,suitable for strong acid or saltwater environments,17-4PH can reach different heat treatment Solution,Quenching and Aging such as H900,H1025 and H1150.
High strength: By appropriate heat treatment, the material strength of 17-4PH can be significantly improved, making it suitable for structural components with higher requirements.
17-4PH H900: This type has undergone heat treatment at 900 ° F (approximately 482 ° C) and has good strength and moderate plasticity.
17-4PH H1025: Processed at 1025 ° F (approximately 552 ° C), suitable for applications that require high toughness and good corrosion resistance.
17-4PH H1150: After heat treatment at 1150 ° F (approximately 621 ° C), it is mainly used to reduce strength and maintain good processability.
Solution treatment: Typically heated at 1040 ° C (approximately 1900 ° F) for 1 hour, then rapidly quenched to form a uniform solid solution to ensure the basic properties of the material.
Quenching: After solution treatment, it is necessary to quickly immerse it in oil or water to cool it quickly and form a martensitic structure. This process is an important step in improving hardness.
Aging treatment: Aging treatment is carried out at a certain temperature, usually between 480-620 ° C, to strengthen the strength and hardness of the material and improve its toughness.
