ASTM A513/A513M-12 pdf free.Standard Specification for Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing.
ASTM A513/A513M covers electric-resistance-welded carbon and alloy steel tubing for use as mechanical tubing.
This specification covers mechanical tubing made from hot- or cold-rolled steel.
This specification covers round, square, rectangular, and special shape tubing.
3. Ordering Information
3.1 Orders for material under this specification should include the following as required to adequately describe the desired material:
3.1.1 Quantity (feet. metres. or number of lengths),
3.1.2 Name of material (electric resistance-welded carbon or alloy steel mechanical tubing).
3.1 .3 Types. conditions and code letters. (See Sections I and 12),
3. 1 .4 Thermal condition, (See 12.2),
3.1.5 Flash condition, (See 12.3),
3.1 .6 Grade designation, if required. (See Section 5),
3.1.7 Report chemical analysis and product analysis, if required (See Sections 6 and 7),
3. 1 .8 Individual supplementary requirements. if required (S1 to S10, inclusive),
3.1.9 Cross section (round, square, rectangular and special shapes),
3.1.10 Dimensions, round, outside and inside and wall thickness (See 8.1 and 8.2) or square and rectangular. outside dimension and wall thickness and corner radii, if required (See 9.1 and 9.2),
3.1.11 Length. round, mill lengths or definite cut length (See 8.3), square and rectangular, specified length (See 9.4),
4. Materials and Manufacture
4.1 The steel may be made by any process.
4.2 If a specific type of melting is required by the purchaser. it shall be as stated on the purchase order.
4.3 The primary melting may incorporate separate degas- sing or refining, and may be followed by secondary melting. such as electroslag or vacuum-arc remelting. If secondary melting is employed, the heat shall be defined as all of the ingots remelied from a single primary heat.
4.4 Steel may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identifica tion of the resultant transition material is required. The producer shall remove the transition material by an established procedure that positively separates the grades。
4.5 Tubes shall be made by the electric-resistance-welded process and shall be made from hot- or cold-rolled steel as specified.
5. Chemical Composition
5.1 The steel shall conform to the requirements as to chemical composition prescribed in Table I or Table 2(See Specification A1040) If no grade is specified, Grades MT 1010 to MT 1020 may be furnished. Analyses of steels other than those listed are available. To determine their availability, the purchaser should contact the producer.
5.2 When a carbon steel grade is ordered under this specification, supplying an alloy grade that specifically re- quires the addition of any element other than those listed for the ordered grade in Tables I and 2 is not permitted.
5.3 Mechanical tubing with improved ductility may be produced from Drawing Steel(Types A and B)， Deep Drawing Steel, or Extra Deep Drawing Steels identified in Specificationsa008/a008m,a101/a101m,ora1039/a1039m. Those Specifications offer guidance in the form of nonmandator lyrical Ranges of Mechanical Properties.
