Suitable Temperature of Different Valve Materials
- May 11, 2018 -

Working temperature is one of the most important feature to design and manufacture valve, below material and suitable using temperature for valve for your information:

1. Cryogenic Service. Temperaure -100℃ ≥ T  ≥ -196℃.

The main material should be austenic stainless steel, after proper heat treatment, the low temperature merchanic properties especial low temperature impacting strength must meet requirement of standard.

Below austenic stainless steel can be used to produce cryogeic valves:

ASTM A351 CF8M,ASTM A351 CF3M,ASTM A351 CF8, ASTM A351 CF3,ASTM A182 F316, ASTM A182 F316L, ASTM A182 F304, ASTM A182 F304L, etc. Cryogenic valve body, bonnet, disc must be high cold treated in liquid nitrogen( -196℃ ) before machine work.


2. Low Temperature Service. Temperature -29℃ ≥ T  ≥ -100℃.

The main material should be austenic stainless steel,ferritic stainless steel, martensitic stainless stee.

Below material can be used to produce low temperature valves:

ASTM A351 CF8M,ASTM A351 CF3M,ASTM A351 CF8, ASTM A351 CF3,ASTM A182 F316, ASTM A182 F316L, ASTM A182 F304, ASTM A182 F304L,ASTM A352 LCA, ASTM A352 LCB, ASTM A352 LCC, ASTM A352 LC1.


3. Non-corrosive service.

The main material be carbon steel in case service is water, steam, gas, oil etc.The material grade is ASTM A216 WCB, ASTM A216 WCC, forged carbon steel ASTM A105. Using temperature range is from -29℃ to 425℃. But general using temperature of carbon steel is not hgiher than 400℃, consider safety factor.


4. High temperature service.

The main material be Cr-Mo casting high temperature steel.

ASTM A217 WC6, ASTM A217 WC9, ASTM A182 F11, ASTM A182 F22, suitable for service water, steam, gas, not suitable for oil contain sulfur.suitable temperature ASTM A217 WC6 and ASTM A182 F11 :-29℃ to 540℃; ASTM A217 WC9 and ASTM A182 F22:-29℃ to 570℃.

ASTM A217 C5, ASTM A182 F5 suitable for service water, steam, gas, and oil contain sulfur.suitable temperature ASTM A217 WC6 and ASTM A182 F11 :-29℃ to 550℃ .
