What does A216 WCB mean?
What does A216 WCB mean?
carbon steel castings
WCB (UNS Code J03002) is covered by ASTM A216 standard, which 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.
What is ASTM A216?
The ASTM A216 specification covers 3 grades of carbon steel (WCA, WCB, and WCC), which feature slight differences in terms of chemical and mechanical properties. ASTM A216 steel castings shall be heat treated and can be manufactured in the annealed, or normalized, or normalized and tempered conditions.
What is the difference between a valve that is manufactured to ASTM A216 WCB and one that is ASTM A105 specifications?
Carbon steel valves are kept in stock in forged ASTM A105 and it’s cast equivalent ASTM/A216-WCB. ASTM A216 WCC has a slightly higher pressure/ temperature rating than A216 WCB as it has a higher yield strength and a slightly higher manganese content.
Is WCB stainless steel?
Both AISI 316 stainless steel and ASTM A216 grade WCB are iron alloys. They have 68% of their average alloy composition in common. For each property being compared, the top bar is AISI 316 stainless steel and the bottom bar is ASTM A216 grade WCB. …
Is WCB cast iron?
Both ASTM A216 grade WCB and ductile cast iron are iron alloys. They have a very high 95% of their average alloy composition in common. There are 28 material properties with values for both materials. For each property being compared, the top bar is ASTM A216 grade WCB and the bottom bar is ductile cast iron.
What is CF8 stainless steel?
Stainless Steel SA-351 CF8 is the cast equivalent of Type 304 Stainless Steel, part of a range of austenitic chromium-nickel alloys that provide good strength and ductility. They are also known as 18/8 stainless due to their chemical composition which includes approximately 18% chromium and 8% nickel by weight.
What killed pipe?
Deoxidized steel (Also known as killed steel) is steel that has some or all of the oxygen removed from the melt during the steelmaking process. Liquid steels contain dissolved oxygen after their conversion from molten iron, but the solubility of oxygen in steel decreases with cooling.
Why killed carbon steel is used?
We say the steel is “killed” because it will quietly solidify in the mould, with no gas bubbling out. As a result, killed steel is dense in structure, uniform in composition, and not so segregative as other types of steels. During the steel making process, oxygen may become dissolved in the liquid metal.
What is the difference between A105 and WCB?
WCB valves by cast liquid forming that can cause tissue segregation and defects and can be used to cast complex workpieces. The ductility, toughness and other mechanical properties of A105 forged steel valves are higher than WCB castings and can bear greater impact force.
What type of steel is WCB?
Carbon Steel
Carbon Steel SA216 WCB, is a Carbon Steel suitable for Fusion Welding in high-temperature service applications: Steel castings for 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 fusion welding.
What’s the different material A216 WCB and A105?
A105 is forged steel, forged carbon steel, suitable for small-size valves or high pressure valves Both are used as valve body. However, the overall cost of A105 valve is much higher than the WCB A216-WCB American Standard material grades, A216 represents the major types of carbon steel Its commonly used brands are:
What’s ASTM A216 WCB for carbon steel castings?
A216 WCB is carbon steel castings for 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 fusion welding. A216 WCB Temperature Range: -29~425°C. A216 WCB Equivalent material: ASTM A105
What kind of material is used for WCB?
Carbon Steel WCB-Casting Material WCB (UNS Code J03002) is covered by ASTM A216 standard, which 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.
What kind of steel is ASTM A216 grade?
ASTM A216 grade WCB is a type of ASTM A216 cast steel. Cited properties are appropriate for the annealed condition. The graph bars on the material properties cards below compare ASTM A216 grade WCB to: cast carbon steels (top), all iron alloys (middle), and the entire database (bottom).
