ASTM A6/A6M-14 pdf free.Standard Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling.
This general requirements specification2 covers a group of common requirements that, unless otherwise specified in the applicable product specification, apply to rolled structural steel bars, plates, shapes, and sheet piling covered by each of the following product specifications issued by ASTM:
1.2 Annex A1 lists permitted variations in dimensions and mass (Note 1) in SI units. The values listed are not exact conversions of the values in Tables 1 to 31 inclusive but are, instead, rounded or rationalized values. Conformance to Annex A1 is mandatory when the “M” specification designation is used.
Note 1—The term “weight” is used when inch-pound units are the standard; however, under SI, the preferred term is “mass.”
5. Materials and Manufacture
5.I The steel shall be made in a basic-oxygen or electric-arc furnace, possibly followed by additional refining in a ladle metallurgy furnace (LMF)or secondary melting by vacuum- arc remelting (VAR)or electroslag remelting(ESR).
5.2 The steel shall be killed.
5.3 The steel shall be strand cast or cast in stationary molds.
5.3.1 Strand Cast:
5.3.1 When heats of the same nominal chemical composition are consecutively strand cast at one time, the heat number assigned to the cast product need not be changed until all of the steel in the cast product is from the following heat. When two consecutively strand cast heats have different nominal chemical composition ranges, the manufacturer shall remove the transition material by an established procedure that positively separates the grades.
5.4 Structural products shall be produced from an as-rolled structural product or from coil.
6. Heat Treatment
6. I Where the structural product is required to be heat treated, such heat treatment shall be performed by the manufacturer, the processor, or the fabricator, unless otherwise specified in the applicable product specification.
NoTE 2-When no heat treatment is required. the manufacturer or processor has the option of heat treating the structural product by normalizing, stress relieving, or normalizing then stress relieving to meet the applicable product specification.
6.2 Where the heat treatment is to be performed by other than the manufacturer. the order shall so state.
6.2. I Where the heat treatment is to be performed by other
an the manufacturer, the structural products shall be accepted on the basis of tests made on test specimens taken from full thickness test coupons heat treated in accordance with the requirements specified in the applicable product specification or in the purchase order. If the heat-treatment temperatures are not specified, the manufacturer or processor shall heat treat the test coupons under conditions the manufacturer or processor considers appropriate, provided that the purchaser is informed of the procedure followed in heat treating the test coupons.ASTM A6/A6M-14 pdf download.
