One of the most important steps when specifying the most appropriate sensor for your application is selecting the wetted material of the process connection (or pressure port). Wetted material is another term for the type of metal that will be in contact with the media in your application. No single metal can economically handle all of the medias that are used in difference processes and industries. Core Sensors offers a wide range of wetted materials to ensure the most adequate compatibility in your application. Below is a listing of the most common wetted materials we offer and the typical use:
17-4PH Stainless Steel (UNS S17400)
This is a high strength, good corrosion resistant martensitic stainless steel. It is also referred to as Type 630 steel. It is ideal for hydraulics and high cyclic applications. 17-4PH is not recommended for hydrogen service, cryogenics, sea water and high temperature operation.
316L Stainless Steel (UNS S31603)
This material is a low carbon version of 316 stainless steel. It is ideal for applications requiring corrosion resistance such as water, oils, lubricants, natural gas, mild acids and hydrogen service*. This steel is not recommended for sea water, high levels of chlorine and hydrogen sulfides.
* Special considerations should be made when specifying 316L SS for hydrogen service. Please visit our Hydrogen application page for more information.
Inconel 718 (UNS N07718)
This material is a super nickel-chromium alloy offering high strength. It is ideal for oil and gas, high temperature operation and sea water applications. Inconel 718 offers resistance against chlorides, which are common in oil and gas operations, stress corrosion and sulfide stress cracking. This metal must not be used in pure high pressure hydrogen applications (See 316L SS above for Hydrogen service).
Hastelloy* C276 (UNS N10276)
This material is a super nickel-molybdenum-chromium alloy offering high corrosion resistance in oil and gas, sea water, chemical processing and high temperature applications. Hastelloy C276 is commonly used with high H2S, wet chloride gas, hypochlorite and many other chemicals found in chemical process applications. This metal must not be used in pure high pressure hydrogen applications (See 316L SS above for Hydrogen service).
Titanium BT9 (Grade 12)
This Titanium alloy is used for high strength, high temperature applications. It is excellent for down hole and aircraft test stand engine exhaust gas pressure measurements. Titanium BT9 is the material used in all of the high temperature sensors from Core Sensors.
This is a broad list of materials offered by Core Sensors and some common applications to consider. We highly recommend the customer verifies the compatibility of the material with a material expert.
