Product Details

Product Detail:

WCB is the valve material, as detailed in the "Standard Specification for ASTM A216 Fusible Welded Carbon Steel Castings for High Temperatures".

chemical composition:

Carbon (C) ≤ 0.302

Manganese (Mn) ≤ 1.002

Phosphorus (P) ≤ 0.04

Sulfur (S) ≤ 0.045

Silicon (Si) ≤ 0.60

Note: For every 0.01% decrease in C, Mn can be increased by 0.04%, but the maximum Mn cannot be higher than 1.28%.

Mechanical properties:


Rel ≥ 250MPa

A ≥ 22%

Z ≥ 35%

WCB is a carbon steel casting grade.

Valve: It is a control component in the fluid delivery system. It has functions such as cut-off, regulation, diversion, anti-backflow, voltage regulation, shunt or overflow relief.

Material: material and texture.

The material of the valve is an important factor related to the temperature, pressure and production process that the valve can withstand.

WCB is a commonly used material in valve manufacturing and is a carbon steel casting grade. In WCB, W means weldable, C means casting, and B means the strength grade of carbon cast steel. Here, the strength grade of carbon cast steel is divided into three grades A, B, and C, where: A is lower strength, B is medium strength, and C is higher strength.

Common materials for WCB forgings are carbon steel (carbon steel) as required by ASTM A 216/A 216M. It is an iron-carbon alloy containing less than ≤0.302% carbon. In addition to carbon, it usually contains a small amount of silicon, manganese, sulfur, and phosphorus.
