Abstract
The invention discloses a formula of a Cr38A alloy material. The formula comprises the following components by weight percent:: 28-30% of nickel, 38-40% of chrome, 0.012-0.015% of carbon and the balance of a small amount of silicon, manganese, phosphor and sulfur. A pump made of the Cr38A alloy material runs in a severe environment for a long term, and is used for the delivery of sulfuric acid, hydraulic acid, hydrofluoric acid, mixed acid containing chloride ion and the like; the pump not only can resist chemical corrosion of acid, alkaline, salt and other corrosive media, but also can not cause corrosion, deformation, aging or fatigue of overflow components when pressure and temperature variation occur in running, thus the integral running efficiency and reliability of the pump are improved, the instability of a lining plastic pump in the running process is changed, the device running service life can achieve more than 15 years, and is far longer than the service life of the lining plastic pump; and the cost of easily damaged components is basically the same with that of the lining plastic pump, and the easily damaged components are long in using period, and are convenient to maintain, and the maintaining cost of users is lowered greatly.
Description
Technical field: the present invention relates to metallic substance, particularly relate to a kind of prescription of Cr38A alloy material.
Background technology; General pump work environment all compares badly; So the work-ing life of pump is also very low, so that improve the work-ing life of pump, just the pump that uses stainless material to process in very important workplace; And this pump cost high, cost an arm and a leg, general medium and small sized enterprises can't afford at all.Also there is methods such as being employed in pump medium overcurrent position lined with fluoroplastic flitch, plastic-blasting to increase acid-proof, the alkali of pump, the intensity of salt; But the burn into that still can cause flow passage components when when moving, running into pressure, temperature variation is out of shape, wears out or be tired; The unstable that occurs in the operational process has increased the maintenance cost of pump.
Summary of the invention: the object of the invention is exactly the prescription that a kind of Cr38A alloy material will be provided, and it can solve pump and use the existing above problem of current material.The objective of the invention is to realize like this, the prescription of Cr38A alloy material is characterized in that: each element content by weight percentage is nickel 28-30%, chromium 38-40%, carbon 0.012-0.015%, and all the other are minor amount of silicon, manganese, phosphorus, sulphur.The pump that the present invention produces adapts to moving under the severe environment for a long time, is used for the conveying of mixing acid such as sulfuric acid, hydrochloric acid, hydrofluoric acid and chloride ion-containing.It can not only acid-and base-resisting, the chemical corrosion of salt and other corrosive medium; And when operation the time runs into pressure, temperature variation, can not cause the burn into distortion, aging or tired of flow passage components, the overall operation efficiency and the safety that have improved pump have changed the unstable that plastic lined pump occurs fully in operational process.The equipment operation life of making can reach more than 15 years, and the work-ing life of consumable accessory is minimum also more than 1 to 3 year, is higher than the work-ing life of plastic lined pump far away.The cost and the plastic lined pump of consumable accessory are basic identical, and the consumable accessory life cycle is long, easy to maintenance, greatly reduce user's maintenance cost.
Embodiment:
The prescription of Cr38A alloy material is characterized in that: each element content by weight percentage is nickel 28-30%, chromium 38-40%, carbon 0.012-0.015%, and all the other are minor amount of silicon, manganese, phosphorus, sulphur.
