Embodiment 1
[0015] Select high-quality martensitic stainless steel hot-rolled bar as the raw material of high-pressure stainless steel pump body, saw the material according to the theoretical weight, heat and forge at 1250-1500°C for 1.8-2.2 hours, and prepare a forging billet, and then immediately Send it into a solid melting furnace, rapidly raise the temperature to a solid solution temperature of 1040 °C at a rate of 90-150 °C / h, heat-preserve and solid solution for 3 hours, and immediately water-cool after leaving the furnace to complete the solid solution treatment.
[0016] Then the solid solution treated forging billet undergoes mechanical rough processing, natural aging, mechanical finishing and inspection of size, appearance, physical and chemical properties in sequence to become the high-pressure stainless steel pump body, which is packaged and put into storage. Among them, the allowance for mechanical rough machining is 1.5mm, and the natural aging time is 12h.
