Scope

In the manufacture of porcelain enameled ware, sheet steel is subjected to forming operations and subsequently to firing of the enamel at temperatures, typically, of 1400 to 1550°F (760 to 844°C). Some steels used for porcelain enameling are subject to grain growth in critically strained areas resulting in loss of strength.

This may lead to easy deformation of the steel and damage to the porcelain enamel coating.

This test method may be correlated with transit or use tests to evaluate the suitability of steel for porcelain enameled ware.

1.1 This test method covers determination of the yield strength of steel specimens after simulated forming and enamel firing operations.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
