Valve material code
The classification of the valve is mainly divided by the purpose and structure. However, we generally use the general taxonomy that is, according to the principle, the role and structure by the division, this method is currently the most common domestic and international classification. Here we press the valve body of different materials, the valve can be divided into: (1) metal valve material: the valve body and other parts made of metal materials. Such as cast iron valves, carbon steel valves, alloy steel valves, copper alloy valves, aluminum valves, lead alloy valves, titanium valves, Monel valves. (2) non-metallic materials Valve: the valve body and other parts made of non-metallic materials. Such as plastic valves, Tao valve, valve, FRP valve. (3) metal valve body lining valve: the body shape of the metal, the internal surface of all the major contact with the media are lining, such as lining valve, lining plastic valve, lining valve and so on. Valve body materials are: C carbon steel, I1Cr5Mo chromium molybdenum steel, HCr13 stainless steel, K malleable iron, L aluminum alloy, P0Cr18Ni9 stainless steel, PL00Cr19Ni10 stainless steel, Q ductile iron, R0Cr12Ni12Mo2 stainless steel, RL00Cr17Ni14Mo2 stainless steel, S plastic, T Copper and copper alloys, Ti titanium and titanium alloys, V Cr-Mo vanadium steel, Z gray cast iron. The following are several stainless steel valve material parameters and the specific use: Material code Chinese abbreviation Application Medium Operating temperature range WCB carbon steel non-corrosive applications, including water, oil and gas Temperature range: -30 ℃ ~ 425 ℃ LCB low temperature carbon steel - low temperature applications , The temperature is as low as -46 ℃, can not be used when the temperature is higher than 340 ℃ LC3 3.5% nickel steel - low temperature applications, the temperature as low as -101 ℃, can not be used in temperatures above 340 ℃ WC6 1.25% chromium 0.5% Molybdenum steel Non-corrosive applications including water, oil and gas Temperature range: -30 ° C to 593 ° C WC9 2.25% Chromium Non-corrosive Applications including water, oil and gas Temperature range: -30 ° C to 593 ° C C5 5% Chromium 0.5% Molybdenum Mildly corrosive or corrosive Applications Non-corrosive Applications Temperature range: -30 ° C to 649 ° C C12 9% Chromium 1% Molybdenum Mildly corrosive or corrosive Applications Non-corrosive Applications Temperature range: -30 ° C to 649 ° C CA6NM 12% Chrome Steel Corrosive Operating Temperature Range: -30 ° C to 482 ° C CA15 12% Chromium Corrosion Operating Temperature Range up to 704 ° C CF8M 316 Stainless Steel Corrosive or Very Low or High Temperature Non Corrosive Applications Temperature Range: -268 ° C To 649 ° C, temperature 425 To the above specified carbon content of 0.04% or more
