1.4564 (17-7PH stainless steel) reducer , is a precipitation-hardening stainless steel reducer featured with high strength, high hardness, excellent fatigue properties, good corrosion resistance and good formability.1.4564 (17-7PH )stainless steel is the best choice for making springs. It has strong corrosion resistance and high tensile strength. It can reach 2000MPA or higher after aging treatment. The most important thing is that the strength is not weaken during long-term usage. This fatigue resistance is due to the addition of AL as a precipitation hardening effect, making the 1.4564 (17-7ph )stainless steel a semi-austenitic and semi-martensitic stainless steel.
1.4565(Alloy 24) stainless reducer is a nitrogen and molybdenum alloyed austenitic stainless steel, resistant to intergranular corrosion and excellent resistance to pitting, crevice corrosion and stress corrosion cracking in sea water and other corrosive media.
application:
1. When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the flow rate requirement does not change much, a reducer must be used.
2. At the inlet of the pump, in order to prevent cavitation, a reducer needs to be used.
3. At the joints with instruments, such as flow meters and regulating valves, reducers are also required in order to cooperate with the joints of the instruments.
