Other grades of wrought carbon exist for specific applications – copies of these grades can be purchased at www. Go back to main menu page all valve materials types Click here. Other grades of cast stainless steels exist for specific applications – copies of these grades can be purchased at www. It is typically used in high temperature applications and is well suited asstm extreme service environments. 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.

A The sum of copper, nickel, chromium, molybdenum and vanadium shall not exceed 1. Work Item s – proposed revisions of this standard. Electroless nickel is uniformly deposited on application making it simpler to apply on complex components as opposed to other hard wearing coatings. CF8M is used in applications where corrosion resistance is a primary concern.
The four common types of heat treatment in valve materials are: 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 cast bad casting which is why most high pressure valves are made with forged steel.
CARBON STEEL VALVES WCB/WCC/A105
Tempering is typically done by heating the metal to temperatures below the critical temperature to increase toughness. Selection will depend upon design and service conditions, mechanical properties, and the high-temperature characteristics.
This is specified for petroleum, natural gas and geothermal production services containing small amounts of H2S. 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.
QT – Quench and Temper – Quenching is a heat treatment in which the metal is heated to a specific 2a16 then cooled quickly to increase hardening. Combining values from the two systems may result in nonconformance with astj standard.
This wcf covers 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.

If this website helps you, please reward GSL with your business and advise your purchasing staff, plant managers and project managers about us! 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. Typically it is applied to ferrous alloys that are heated above their critical temperature and allowed to cool in open air. For x216 information on Inconel visit http: Steel castings s216 adhere to chemical composition and tensile property requirements, which include tensile strength, yield strength, elongation, and reduction of area.
This specification covers carbon steel castings wccc valves, flanges, fittings, or other pressure-containing parts for high-temperature service and of quality suitable for assembly with other castings or wrought-steel parts by aztm welding. Furnace temperatures for heat treating shall be effectively controlled by pyrometer. The order desk is 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.
At Global Supply Line the same knowledge and effort we put into this website goes into every product we sell. We keep extensive stocks which are inventoried in our warehouses. NT – Normalize and Temper – Temper is an additional step used on martenistic steel making it asm brittle. The coating is applied to less expensive metals which can significantly reduce cost.
N – Normalize – Normalizing is a technique used to provide consistency in grain size throughout an alloy. It is usually used to soften the metal to improve machinability or increase electrical conductivity. Aatm more information on Monel visit http: Of the three steel grades WCB is the common grade for regular temperature applications for cast steel valves.
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. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Stellite 6 is the most common form of stellite in valves.
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. 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.
Readers are encouraged to consult other sources and talk with engineering professionals to obtain further information. Global Supply Line stocks and indents the following valves in all grades: 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.
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. Stellite is trademarked by Deloro Stellite Company. 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.
D By agreement, the limit for columbium may be increased up to 0.
