The four common types of heat treatment in valve materials are: These grades are all “cast” grades, meaning they are made through “casting”, a manufacturing process where a liquid material is poured into a mold and allowed to harden. N – Normalize – Normalizing is a technique used to provide consistency in grain size throughout an alloy.
These grades are all “cast” grades meaning they are made through “casting” which is a manufacturing process where a astn material is poured into a mold and allowed to harden.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Furnace temperatures for heat treating shall be effectively controlled by pyrometer. At Global Supply Line the same knowledge and effort we put into this website goes into every product we sell. Cast valves are typically less expensive than their forged counterparts for larger bore valves – though as a result of the casting process there is the potential for a porous qstm bad casting which is why most high wstm valves are made with forged steel.
Historical Version s wccc view previous versions of standard. This specification covers stainless steel castings for valves, fittings, flanges and other pressure-containing parts for low temperature service and the quality required for assembly with other castings or wrought steel parts by fusion welding.
For higher percentages of H2S Global Supply Line also stocks upstream sstm, corrosion resistant, alloy valves and chokes manufactured in chrome-moly and that resists sulfide stress corrosion and hydrogen embrittlement cracking.
This abstract is a brief summary of the referenced standard. CF8M is used in applications where corrosion resistance is a primary concern. Other grades of wrought carbon exist for specific applications – copies of these grades can be purchased at www. It is applied at various thicknesses – 1mm to 3mm with the greater the thickness the better the resiliancy of the coating; 3mm is the preferred thickness in the valve industry.
QT – Quench and Temper – Quenching is a heat treatment in which the metal is heated to a specific temperature then cooled quickly to increase hardening. Largest valve stockist Southern Hemisphere shipping worldwide.
This is specified for petroleum, natural gas and geothermal production services containing small amounts of H2S. NT – Normalize and Temper wvc Temper is an additional step used on martenistic steel making it less brittle.

Refer to low temperature carbon steel overview at this website go to link below. The order desk is Cast valves are typically less expensive than their forged counterparts for larger bore valves – though as a result of the casting process the potential for a porous cast bad casting is why most high pressure valves are made with forged steel. Of the three steel grades LCC is the common grade for regular temperature applications for cast steel valves.
B The sum of chromium and molybdenum shall not exceed 0. Of the three steel grades WCB is the common grade for regular temperature applications for cast steel valves.
D By agreement, the limit for columbium may be increased up to 0. Readers are encouraged to consult other sources and talk with engineering professionals to obtain further information. Go back to main menu page all valve materials types Click here. Monel is also trademarked by Special Metals Corporation and is typically used in high corrosion environments like in seawater valves.
For more information on heat treatments visit http: Steel castings shall adhere to chemical composition and tensile property requirements, which include tensile strength, yield strength, elongation, and reduction of area. Stellite 6 is the most common form of stellite in valves. Other grades of cast stainless steels exist for specific applications – copies of these grades can be purchased at www. Covered here are three grades of carbon steel Grades WCA, WCB, and WCCthe selection of which shall depend on the design and service conditions, mechanical properties, and the high temperature characteristics.
CARBON STEEL VALVES WCB/WCC/A105
It is usually used to soften the metal to improve machinability or increase electrical conductivity. Stellite is trademarked by Deloro Stellite Company.
We keep extensive stocks which wcd inventoried in our warehouses. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. A The sum of copper, nickel, chromium, molybdenum and vanadium shall not exceed 1.
