2007 SECTION II, PART A SA-276 SPECIFICATION FOR STAINLESS STEEL BARS AND SHAPES SA-276 (Identical with ASTM Specification A 276-97.) Scope 1.1 This specification covers hot-finished or cold-finished bars except bars for reforging (Note 1) It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels The free-machining types (Note 2), for general corrosion resistance and high-temperature service, are covered in a separate specification Ordering Information 3.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this specification Such requirements may include but are not limited to the following: 3.1.1 Quantity (weight or number of pieces); 3.1.2 Name of material: stainless steel; 3.1.3 Form (bars, angles, etc.); 3.1.4 Condition (Section 5.1); NOTE —For bars for reforging, see Specification A 314 3.1.5 Finish (Section of Specification A 484 /A 484M); NOTE —For free-machining stainless bars designed especially for optimum machinability, see Specification A 582 /A 582M 3.1.6 Surface preparation of shapes (Section of Specification A 484 /A 484M); NOTE —There are standards covering high nickel, chromium, austenitic corrosion, and heat resisting alloy materials These standards are under the jurisdiction of ASTM Subcommittee B02.07 and may be found in Annual Book of ASTM Standards, Vol 02.04 3.1.7 Applicable dimensions including size, thickness, width, and length; 1.2 The values stated in inch-pound units are to be regarded as the standard 3.1.8 Cross section (round, square, etc.); 3.1.9 Type or UNS designation (Table 1);
