What is ASTM A216 Gr WCB?
What is ASTM A216 Gr WCB?
astm a216 gr wcb ball valve is a type of ball valve that is made up of the WCB material. The size of the valve is 20 inches and the pressure class is 300. The ASTM A216 standard also covers the API Trim 8 dimensions. The astm a216 gr wcb gate valve has end to end dimensions as 991mm RF, 991mm BW and 1010mm RTJ.
What means WCB valve?
WCB is a grade of Carbon steel used for valve body . It is a type of ASTM A216 cast steel. WCB is suitable for large diameter valves.
Is WCB cast or forged?
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 is the difference between WCB and WCC material?
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 A105 cast or forged?
A105 valve can be forged by plastic deformation to improve the internal structure, good mechanical properties and even grain size. WCB valves by cast liquid forming that can cause tissue segregation and defects and can be used to cast complex workpieces.
Which is better WCC or 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….Chemical Composition A105/WCB/WCC/LF2.

Is WCB stainless steel?
Both AISI 304 stainless steel and ASTM A216 grade WCB are iron alloys. They have 71% of their average alloy composition in common. There are 29 material properties with values for both materials.
What is WCB in civil engineering?
In civil engineering surveying, bearing is very important to get the direction of a survey line. The whole circle bearing (W.C.B) is a common notation system of bearings.
