If secondary melting processes are employed, the heat ana

The chemical composition thus determined, or that determined froma product analysis made by the tubular product manufacturer shall conform to the requirements specified.6.2.1 For steels ordered

43、under product specifications referencing this specification of general requirements, the steel shall notcontain an unspecified element, other than nitrogen for stainless steels, for the ordered grade to the extent that the steel conformsto the requirements of another grade for which that element is

44、a specified element having a required minimum content. For thisrequirement, a grade is defined as an alloy described individually and identified by its own UNS designation in a table of chemicalrequirements within any specification listed within the scope as being covered by this specification.6.3 P

45、roduct AnalysisProduct analysis requirements and options, if any, shall be as contained in the applicable productspecification.7. Mechanical Properties7.1 Method of Mechanical TestsThe specimens and mechanical tests required shall be in accordance with Test Methods andDefinitions A370, especially An

46、nex A2 thereof, or Test Methods A1058.7.1.1 Unless otherwise specified in the ordering requirements, Test Methods A1058 shall apply when the metric version of theproduct specification is specified.7.2 Specimens shall be tested at room temperature.7.3 Small or subsize specimens as described in Test M

47、ethods and Definitions A370 or Test Methods A1058 may be used onlywhen there is insufficient material to prepare one of the standard specimens. When using small or subsize specimens, the largestone possible shall be used.8. Tensile Requirements8.1 The material shall conform to the requirements as to

48、 tensile properties in the applicable product specification.8.2 The yield strength, if specified, shall be determined corresponding to a permanent offset of 0.2 % of the gauge length or toa total extension of 0.5 % of the gauge length under load.8.3 If the percentage of elongation of any test specim

49、en is less than that specified and any part of the fracture is more than 34in. 19.0 mm from the center of the gauge length, as indicated by scribe marks on the specimen before testing, a retest shall beallowed.9.
