  Designation: A 519 – 03 Standard Specification for Seamless Carbon and Alloy Steel Mechanical Tubing 1 This standard is issued under the fixed designation A 519; the number immediately following the designation indicates the year of srcinal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon ( e ) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. This standard replaces QQ-T-00825 and QQ-T-830. 1. Scope* 1.1 This specification covers several grades of carbon andalloy steel seamless mechanical tubing. The grades are listed inTables 1-3. When welding is used for joining the weldablemechanical tube grades, the welding procedure shall be suit-able for the grade, the condition of the components, and theintended service.1.2 This specification covers both seamless hot-finishedmechanical tubing and seamless cold-finished mechanicaltubing in sizes up to and including 12  3  ⁄  4  in. (323.8 mm) outsidediameter for round tubes with wall thicknesses as required.1.3 The tubes shall be furnished in the following shapes, asspecified by the purchaser: round, square, rectangular, andspecial sections.1.4 Supplementary requirements of an optional nature areprovided and when desired shall be so stated in the order.1.5 The values stated in inch-pound units are to be regardedas the standard. The values given in parentheses are forinformation only. 2.

All others are normally manufactured by thebasic-open-hearth process but may be manufactured by the basic-electric-furnace process with adjustments in phosphorus and sulfur. B  Grades shown in this table with the letter B, such as 50B40, can be expected to have 0.0005 % minimum boron control. C  The phosphorus sulfur limitations for each process are as follows:Basic electric furnace 0.025 max % Acid electric furnace 0.050 max %Basic open hearth 0.040 max % Acid open hearth 0.050 max % D  Minimum and maximum sulfur content indicates resulfurized steels. E  The purchaser may specify the following maximum amounts: copper, 0.30 %; aluminum, 0.050 %; and oxygen, 0.0015 %. 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 secondarymelting is employed, the heat shall be defined as all of theingots remelted from a single primary heat.4.4 Steel may be cast in ingots or may be strand cast. Whensteel of different grades is sequentially strand cast, identifica-tion of the resultant transition material is required. Theproducer shall remove the transition material by an establishedprocedure that positively separates the grades.4.5 Tubes shall be made by a seamless process and shall beeither hot finished or cold finished, as specified.4.6 Seamless tubing is a tubular product made without awelded seam. It is manufactured usually by hot working steeland, if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimen-sions and properties. 5. Chemical Composition 5.1 The steel shall conform to the requirements as tochemical composition prescribed in Table 1 (Low Carbon MTGrades), Table 2 (Higher Carbon Steels), Table 3 (AlloyStandard Steels) and Table 4 (Resulfurized or Rephosphorized,or Both, Carbon Steels).5.2 Grade MT1015 or MTX1020 will be supplied at theproducer’s option, when no grade is specified.5.3 When a carbon steel grade is ordered under this speci-fication, supplying an alloy grade that specifically requires theaddition of any element other than those listed for the orderedgrade in Table 1 and Table 2 is not permitted.5.4 Analyses of steels other than those listed are available.To determine their availability, the purchaser should contact theproducer. 6. Heat Analysis 6.1 An analysis of each heat of steel shall be made by thesteel manufacturer to determine the percentages of the ele-ments specified; if secondary melting processes are used, theheat analysis shall be obtained from one remelted ingot or theproduct of one remelted ingot of each primary melt. The heatanalysis shall conform to the requirements specified, exceptthat where the heat identity has not been maintained or wherethe analysis is not sufficiently complete to permit conformanceto be determined, the chemical composition determined from aproduct analysis made by the tubular manufacturer shallconform to the requirements specified for heat analysis. Whenrequested in the order or contract, a report of such analysesshall be furnished to the purchaser. 7. Product Analysis 7.1 Except as required by 6.1, a product analysis by themanufacturer shall be required only when requested in theorder.7.1.1  Heat Identity Maintained  —One product analysis perheat on either billet or tube.
