1.1 This specification covers three classes of gray iron suitable for castings exposed to temperatures encountered in such service as grate bars, stoker links, stoker parts, oil still furnace parts, firebox parts, ingot molds, glass molds, caustic pots, and metal melting pots.

Note 1--This specification is general, covering cast irons normally used for the above types of service, at temperatures as high as 1400oF (760oC). It is not intended to imply that all three classes are suitable throughout this entire temperature range without regard to actual service stresses. Some are suitable for long service at the lower temperatures only, unless low stresses are involved.

1.2 The three classes of gray iron covered by this specification are as follows:

1.2.1 Class I, possessing superior resistance to thermal shock,

1.2.2 Class II,possessing average resistance to thermal shock and a moderately good tensile strength (tensile strengths above 30000 psi (207 MPa) may be expected), and

1.2.3 Class III, possessing a higher tensile strength than either Classes I or II (tensile strengths as high as 40000 psi (276 MPa) may be expected).

1.3 The values stated in inch-pound units are to be regarded as the standard.
