B The sum of chromium and molybdenum shall not exceed 0.
A – Anneal – This is a general term in which metal is heated to a specific temperature then cooled at a controlled rate that results in a refined micro structure. Stellite is trademarked by Deloro Stellite Company. CF8M is used in applications where corrosion resistance is a primary concern. It is typically used wc high temperature applications and is well suited for extreme service environments. For higher percentages of H2S Global Supply Line also stocks upstream wellhead, corrosion resistant, alloy valves and chokes manufactured in chrome-moly and that resists sulfide stress corrosion and wccc embrittlement cracking.
This specification covers carbon steel castings for valves, fittings, flanges and other pressure-containing parts for high temperature service and the quality required for assembly with other castings or wrought steel parts by fusion welding.
This is specified for petroleum, natural gas and geothermal production services containing small amounts of H2S. This quick article is designed to be a starting point for newcomers to the “valve game”; specifically for those on the order desk AKA – Inside Sales.
These grades are all “cast” grades meaning they are made through “casting” which is a manufacturing process where a liquid material is poured into a mold and allowed to harden. Of the three steel grades LCC is the common grade for regular temperature applications for cast steel valves.
The surface of castings shall be free of adhering elements such as sand, cracks, hot tears, and other discontinuities, and as such be repair welded when judged appropriate.
These grades are all “cast” grades, meaning they are made through “casting”, a a126 process where a liquid material is poured into a mold and allowed to harden. Tempering is typically done by heating the metal to temperatures below the critical temperature to increase toughness.
The Valve Pipeline
The order desk is A The sum of copper, nickel, chromium, molybdenum and vanadium shall not exceed 1. Of the three steel grades WCB is the common grade for regular temperature applications for cast steel valves.
The values stated in each system may not be wstm equivalents; therefore, each system shall be used independently of the other. This specification wwcc carbon 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.
CARBON STEEL VALVES WCB/WCC/A105
For more information on heat treatments visit http: Furnace temperatures for heat treating shall be effectively controlled by pyrometer. Castings shall be heat treated and furnished, as appropriate to their design and chemical composition, in the annealed, or normalized, or normalized and tempered conditions after they have been allowed to cool below the transformation range.
Electroless nickel is uniformly deposited on application making it simpler to apply on complex components as opposed to other hard wearing coatings. Other grades of cast stainless steels exist for specific applications – copies of these grades can be purchased at www.
Global Supply Line stocks and indents the following valves in all grades: The coating is applied to less expensive metals which can significantly reduce cost.
For more information on Inconel visit http: It is illegal to copy, however it is permissable to link another website to any page at this website. The four common types of heat treatment in valve materials are: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Global Supply Line offers valves in a wide variety of material combinations in carbon steel, stainless steels, exotic and special materials. It is applied at various thicknesses – 1mm to 3mm with the greater the thickness the better the resiliancy wxc the coating; 3mm is the preferred thickness in the valve industry. Stellite 6 is the most common form of stellite in valves. Click here to view our stocklist.

If this website helps you, please reward GSL with your business and advise your purchasing staff, plant managers and project managers about us! It is usually used to asfm the metal to improve machinability or increase electrical conductivity. At Global Supply Line the same knowledge and effort we put into this website goes into every product we sell.
Selection will ashm upon design and service conditions, mechanical properties, and the high-temperature characteristics. Historical Version s – view previous versions of standard. 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.
All information contained in this website is intended for educational purposes only. Typically it is applied to ferrous alloys that are heated above their critical temperature and allowed to cool in open air.
Inconel is trademarked by Special Metals Corporation. NT – Normalize and Temper – Temper is an additional step used on martenistic steel making it less brittle. Go back to main menu page all valve materials types Click here.
