Zinc coatings shall be tested and conform to weight/mass and bending requirements in relation to coating thickness.1.1 This specification covers steel sheet, produced by the Twin-Roll Cast process (see Appendix X2) and zinc-coated (galvanized) by the hot-dip process in coils and cut lengths.NOTE 1: See Appendix X2 for a description of the Twin-Roll Cast process.1.2 The product is produced in various zinc coating weights [masses] or coating designations as shown in Table 1.1.3 Product furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A924/A924M unless otherwise provided herein.1.4 The product is available in a number of designations, grades, and classes and in the two following general categories that are designed to be compatible with different application requirements.1.4.1 Steels with mandatory chemical requirements and typical mechanical properties.1.4.2 Steels with mandatory chemical requirements and mandatory mechanical properties.1.5 This material is available in the following sizes:1.5.1 Thickness—up to 0.078 in. [2.0 mm].1.5.2 Width—up to 79 in. [2000 mm].1.6 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification.1.7 Units—This specification is applicable to orders in either inch-pound units (as A1063) or SI units (as A1063M). Values in inch-pound and SI units are not necessarily equivalent. Within the text, SI units are shown in brackets. Each system shall be used independently of the other.1.8 Unless the order specifies the “M” designation (SI units), the product shall be furnished to inch-pound units.1.9 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.1.10 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 ductile iron castings for use in pressure containing paper mill dryer rolls. The castings shall be stress relieved through heat treatment and shall undergo chemical analysis and conform to the required chemical composition in total carbon, silicon, phosphorus, and sulfur. Tension test specimens shall be obtained from test coupons poured from the same iron as the castings represented and shall conform to the prescribed mechanical properties such as yield strength, tensile strength, and elongation. Hardness test shall be conducted on the material and shall meet the required Brinell hardness value.1.1 This specification covers ductile iron castings for use in pressure-containing paper mill dryer rolls at temperatures up to 450 °F [230 °C].1.2 No precise quantitative relationship can be stated between the properties of the iron in various locations of the same casting or between the properties of a casting and those of a test specimen cast from the same iron (see Appendix X1).1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3.1 Exception—Within the text, the SI units are shown in brackets.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 five grades of as-welded, wrought austenitic stainless steel fittings for low-pressure piping and for low and moderate temperatures and general corrosive service. The fittings shall be made from flat-rolled steel which shall be in the solution annealed condition. The fittings shall be formed by a hot or cold process and shall be welded by a shielded welding process with or without the addition of filler metal. Heat analysis and product analysis shall be performed where in the steel fittings shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, titanium, columbium, tantalum, and nitrogen. The steel materials shall also undergo mechanical tests and shall conform to the required values of tensile strength, yield strength, elongation, and hardness.1.1 This specification covers five grades of as-welded, wrought austenitic stainless steel fittings for low-pressure piping and intended for low and moderate temperatures and general corrosive service. Users should note that certain corrosive conditions may restrict the use of one or more grades. For applications requiring a product that requires heat treatment or full pressure rating, refer to Specification A403/A403M. The term “fittings” applies to butt and socket welding parts such as 45° and 90° elbows, tees, reducers, wyes, laterals, crosses, and stub ends.1.2 This specification covers as-welded fittings 3 through 48 in. [75 through 1225 mm] in outside diameter and in nominal wall thicknesses 0.062 through 0.500 in. [1.6 through 12.7 mm]. Table 1 and Table 2 list the common diameters and nominal thicknesses of fittings in this specification.1.3 This specification does not apply to cast fittings. Cast austenitic steel fittings are covered by Specification A351/A351M.1.4 Optional supplementary requirements are provided for fittings where a greater degree of examination is desired. These supplementary requirements call for additional tests. When desired, one or more of these may be specified in the order.1.5 This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable “M” specification designation (SI units), the material shall be furnished to inch-pound units.1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.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.
