The temperature used by each type of valve material

Each type of valve material can be selected according to the actual working conditions, the use of each material temperature is very different, there are room temperature type, medium temperature type, low temperature type, ultra-low temperature, corrosion resistance, high temperature and high temperature type special materials; Relative to high-pressure products, the material of forging manufacturing should be selected, and the chemical medium should consider the material performance.

WCB Carbon Steel ASTM A216 Non-corrosive applications including water, oil and gas, temperature range: -30 ° C to +425 ° C LCB Low temperature Carbon Steel ASTM A352 for low temperature applications, temperatures as low as -46 ° C cannot be used in fields above +340 ° C WC9 2.25 Chromium ASTM A217 Non-corrosive applications including water, oil class WC9 and gas, temperature range: -30 ° C to +593 ° C

CF8M 316 Stainless Steel ASTM A351 Corrosive or ultra-low or high temperature non-corrosive applications, temperature range: -268 ° C to +649 ° C, temperature above +425 ° C to specify carbon content 0.04% and above WC6 1.25% Chromium 0.5% Molybdenum steel ASTM A217 Non-corrosive applications, including water, oil and gas, temperature range: -30 ° C to + C5 5% Chromium 0.5% Molybdenum ASTM A217 Mild corrosive or aggressive applications and non-corrosive applications, temperature range: -30 ° C to +649 ° C

CF3M 316L Stainless Steel ASTM A351 Corrosive or non-corrosive applications, temperature range up to +454℃ CA6NM(4) 12% Chrome Steel ASTM A487 Corrosive applications, temperature range: -30 ° C to +482 ° C CA15(4) 12% Chromium ASTM A217 for corrosive applications with temperatures up to +704 ° C

CF8 304 Stainless Steel ASTM A351 Corrosive or ultra-low or high temperature non-corrosive applications, temperature range: -268 ° C to +649 ° C Temperature above +425 ° C to specify carbon content 0.04% and above CF8C 347 Stainless steel ASTM A351 Mainly used in high temperature, corrosive applications, temperature range: -268 ° C to +649 ° C, temperature above +540 ° C to specify carbon content 0.04% and above C12 9% Chromium 1% molybdenum ASTM A217 Slightly corrosive or aggressive applications and non-corrosive applications, temperature range: -30 ° C to +649 ° C

CF3 304L Stainless Steel ASTM A351 for corrosive or non-corrosive applications up to +425 ° C M35-1 CY40 Inconel alloy ASTM A494 performs well in high temperature applications. It has good corrosion resistance to strong corrosive fluid media. CN7M alloy steel ASTM A351 has good resistance to hot sulfuric acid corrosion at temperatures up to +425 ° C

Monel ASTM A494 weldable grade. Good resistance to all common organic acids and salt water corrosion. It also has high corrosion resistance to most alkaline solutions, temperatures up to +400℃ N7M Haust nickel alloy B ASTM A494 is particularly suitable for processing hydrofluoric acid at various concentrations and temperatures. It has good resistance to sulfuric acid and phosphoric acid corrosion at temperatures up to +649℃. CW6M Haster Nickel alloy C ASTM A494 has good resistance to strong oxidation environment corrosion. It has very good properties at high temperatures, and has very high corrosion resistance of p-formic acid (formic acid), phosphoric acid, sulfite and sulfuric acid at temperatures up to +649℃
