A 216 WCB

A 216 WCB

A 216 WCB

(OP)
Hi everyone,
Can someone help me find complete technical specifications for A 216 WCB.
I want to know the resiliance at -30 Celsius and the other data.
Thank you.

A 216 is an ASTM Specification for castings, carbon, suitable for elevated temperature service. The chemical composition is as follows;

0.30% max C
1.00% max Mn
0.04% max P
0.045% max S
0.6% max Si
with other specified residual elements of
0.30% max Cu
0.50% max Ni
0.50% max Cr
0.20% max Mo
0.03% max V

At -30 deg C (-22 deg F), the tensile properties will probably not be that different from those reported at room temperature. The following are mechanicals for WCB;

UTS - 70 to 95 Ksi
YS min - 36 Ksi
Elongation, 2" gage, min - 22%
Reduction of area, min - 35%

The resilience is a measure of the amount of energy stored by a material subjected to elastic deformation. You could go about this as follows;

Using Young's Modulus E of 30 x 10^6 psi, and knowing the stress you are interested in (this stress must be below the yield strength of WCB),

known stress /E = corresponding elastic strain

resilience = 0.5 * stress * strain

For medium carbon steel the modulus of resilience is reported to be 33.75 psi

RE: A 216 WCB

WCB cast steel will not prove highly ductile at -30 C.  Its impact toughness properties will very likely be low.
