Pump corrosion resistant materials selection reference table

Brief introduction: Pump corrosion resistant material selection reference table Nitric acid (hno3) General characteristics: Is an oxidizing medium. Concentrated hno3 working temperature is generally below 40 â„ƒ, element cr, si is anti-oxidation. Containing si, cr stainless steel and other materials for the thick hno3 Corrosion ideal material. High silicon cast iron (stsi15r): all the temperature below 93%; high chromium cast iron (cr28): all the temperature below 80%; stainless steel (sus304, sus304l, sus316, sus316l): all temperature below 80% (0 cr13ni7si4): all the temperature below 98%; industrial titanium (ta1, ta2): all the temperature below the boiling point (except smoke); industrial pure aluminum (ai): all temperature at room temperature For containers); cd-4mcu age hardening alloy: all the temperature below the boiling point; due to Nair, Hastelloy c, gold, tantalum, etc. have good corrosion resistance. General characteristics of sulfuric acid (h2so4): the boiling point increases with increasing concentration. Such as: concentration of 5%, its boiling point is 101 â„ƒ; concentration of 50%, its boiling point is 124 â„ƒ; concentration of 98%, its boiling point is 332 â„ƒ. Concentration below 75% of the reduction (or neutral), more than 75% of the oxidation. Stainless steel (sus316, sus316l): temperature below 0 â„ƒ, the concentration of about 20%; 904 steel (sus904, sus904l): suitable temperature 40 ~ 60 â„ƒ, the concentration of 20 to 75%; temperature 80 â„ƒ, Cast iron (stsi15r): various concentrations between room temperature and 90 â„ƒ; various concentrations of blunt lead, hard lead and room temperature; s-05 steel (0 cr13ni7si4): concentrated sulfuric acid below 90 â„ƒ, concentrated sulfuric acid â„ƒ); Road US special alloy, acid-resistant alloy. Ordinary carbon steel: more than 70% concentrated sulfuric acid at room temperature; cast iron: concentrated sulfuric acid at room temperature; Monel, nickel metal, due to Nile: medium temperature sulfuric acid; titanium molybdenum alloy (ti-32mo) 60% sulfuric acid and 98% sulfuric acid below 50 Â° C .; Hastelloy b, d: 75% sulfuric acid below 100 Â° C .; Hastelloy c: various concentrations around 100 Â° C; 60 ~ 90% of the room temperature sulfuric acid (hcl) General characteristics: Reducing medium, the maximum concentration of 36 ~ 37%. Boiling point: 110 Â° C at 20%; 50 Â° C at 20-36%; therefore, the maximum temperature for hydrochloric acid is 50 Â° C. Metallic molybdenum (ta): hydrochloric acid is the best corrosion-resistant materials, but the price is expensive, commonly used in the measurement of precision equipment required; Hastelloy b: temperature â‰¤ 50 â„ƒ, 36% concentration of hydrochloric acid; 32mo): full temperature and full strength; nickel-molybdenum alloy (ch1orimetz, 0ni62mo32fe3): full temperature and full concentration; industrial titanium (ta1, ta2): room temperature below 10% hydrochloric acid; zxsnm (l) alloy (00ni70mo28fe2): temperature The concentration of phosphoric acid (h3po4) in hydrochloric acid at a concentration of 36% is generally 30-40% at 50 Â° C and the temperature is 80-90 Â° C. Phosphoric acid usually contains h2so4, f ions, cl ions and silicates. Stainless steel (sus316, sus316l): the concentration of less than 85% of the boiling point of phosphoric acid; durimet20 (alloy No. 20): concentration of 85% or less, the temperature below the boiling point, corrosion resistant alloy; cd-4mcu: age hardening alloy, Alloy; high silicon cast iron (sts15r), high chromium cast iron (cr28): suitable for various concentrations below the boiling point of phosphoric acid. 904,904l: various concentrations of phosphoric acid below the boiling point; inco11oy825: phosphoric acid of various concentrations below the boiling point. Hydrofluoric acid (hf) General characteristics: Hydrofluoric acid is very toxic. High-silicon castings, ceramics and glass are generally resistant to most acids, but hydrofluoric acid erodes them. Magnesium (mg): ideal for hydrofluoric acid corrosion resistant materials, generally only containers; Titanium: for the concentration of 60 to 100% (room temperature state), the concentration of less than 60% rapid increase in corrosion; Monel: Yes Hydrofluoric acid resistant extruded material, resistant to all temperatures and all concentrations (including boiling point); Ag (ag): boiling hydrofluoric acid. Used for measuring device. General characteristics of caustic soda (naoh): caustic soda corrosion intensified with increasing temperature. sus340, sus304l, sus316, sus316l: concentration of 42%, room temperature to 100 â„ƒ; nickel cast iron (stnicr202): the concentration of 40% or less, the temperature below 100 â„ƒ; inco11oy804,825: 42% naon + nacl up to 150 â„ƒ; Pure nickel: 42% naon + nacl up to 150 â„ƒ; Monel: high temperature, high concentration sodium caustic soda (na2co3) soda containing 20-26% nacl, 78% cl2,2-5% co2, The range of variation is 32 ~ 70 â„ƒ. High silicon cast iron: Suitable for soda ash with temperature of 32-70 â„ƒ and concentration of 20-26%. Industrial Pure Titanium: At present, several large-scale soda ash plant mother liquor and other media adopt titanium pump made of titanium. Petrochemical, pharmaceutical, food and other petroleum: 0cr13, 1cr13, 1cr17; petrochemical: 1cr18ni9 (304), 1cr18ni12mo2ti, (sus316); formic acid: 904,904l; acetic acid: titanium (ti) sus316, sus316l; Food: 1cr18ni9, 0cr13, 1cr13. Ordering Information: According to the conditions of use to determine the pump specifications, materials, shaft seal type and prime mover; order should provide flow, lift, suction pressure, the amount of equipment cavitation and the proportion of media, temperature, saturated steam at the operating temperature Pressure, inflammable, explosive, toxic, corrosive, crystalline and whether to allow liquid into the medium
