This specification covers cold-finished carbon and alloy steel bars for heat treatment, machining into components, or for as-finished condition as shafting or in constructional applications. The steel materials shall be cold drawn, turned, ground, polished, hot wrought, cold rolled, and heat treated. The steel specimens shall undergo chemical analysis.1.1 This specification covers cold-finished carbon and alloy steel bars produced in straight length and coil. Cold-finished bars are suitable for heat treatment, for machining into components, or for use in the as-finished condition as shafting, or in constructional applications, or for other similar purposes (Note 1). Grades of steel are identified by grade numbers or by chemical composition.NOTE 1: A guide for the selection of steel bars is contained in Practice A400.1.2 Some end uses may require one or more of the available designations shown under Supplementary Requirements. Supplementary requirements shall apply only when specified individually by the purchaser.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers cold-drawn buttweld carbon steel tubes for use as round, square, rectangular or special shape mechanical tubing. The carbon steel can be made unless a specific type of melting process is required by the purchaser. Heat and product analysis shall be made to determine the specified percentages of chemical elements to which steel tubes shall conform to. The tubing shall be free of injurious defects and shall have a workmanlike finish. Unless otherwise specified, both outside and inside surfaces of the tubing shall be coated with a film of rust-retarding oil before shipping.1.1 This specification covers cold-drawn buttweld carbon steel tubes for use as mechanical tubing.1.2 This specification covers round, square, rectangular, and special shape mechanical tubing.1.3 Round tube size ranges covered are outside diameters up to 3 1/2 in. (88.9 mm) and wall thickness from 0.035 to 0.500 in. (0.89 to 12.70 mm).1.4 Optional supplementary requirements are provided and, when desired, shall be so stated in the order.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 This product is available in various grades (Section 6   Tables 1 and 2 and conditions (Section 5).1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers nominally 17.5% Cr free-machining ferritic stainless soft magnetic alloy produced or supplied expressly in cold-finished bar form for use in magnetic cores and other parts requiring a corrosion-resistant, high permeability, low-coercivity steel. This specification does not cover either cast parts or parts produced by powder metallurgy techniques. Two specific alloy types are covered distinguished by different silicon levels. Required measurements include chemical analysis and dc magnetic property measurement. The magnetic properties depend both on the grade and the dimensions. Apart from the requirements, the specification contains useful appendices discussing the magnetic testing of these alloys and typical magnetic and physical properties.1.1 This specification covers free-machining ferritic stainless soft magnetic alloy produced or supplied expressly in cold-finished bar form for use in magnetic cores and other parts requiring a high permeability, low-coercivity stainless steel.1.1.1 This specification does not cover either cast parts or parts produced by powder metallurgy techniques.1.2 Two specific alloy types are covered. The primary constituents are shown in Table 1. These types have corrosion resistance similar to AISI Type 430F and Type 430F, Specification A582/A582M.1.3 This specification covers only these alloy types supplied in cold-finished bars in cross-sectional shapes such as rounds, squares, hexagons, and octagons with diameters (diagonals) greater than or equal to 6.35 mm (0.250 in.) and less than or equal to 41.5 mm (1.63 in.).21.4 Certain cold-finished round bar products are capable of being supplied mill annealed to required magnetic properties such as low coercivity. The size range that can be mill annealed is from 6.35 to 41.5 mm (0.250 to 1.63 in.). Other products of these alloys cannot be mill annealed to produce equivalently low coercivity; hence, the final machined parts should be heat treated as recommended by the producer.1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
