1.1 These test methods provide simple guidelines for deciding whether a duplex grain size exists. The test methods separate duplex grain sizes into one of two distinct classes, then into specific types within those classes, and provide systems for grain size characterization of...
5.1 These test methods cover procedures for determining the mean grain size, and the distribution of grain intercept lengths or grain areas, for polycrystalline metals and nonmetallic materials with equiaxed or deformed grain shapes, with uniform or duplex grain...
This specification establishes the requirements brass plates, sheets, strips, and rolled bars made from UNS C21000, C22000, C22600, C23000, C24000, C26000, C26800, C27200, or C28000. Plates are generally available only in the hot-rolled temper. The standard tempers of as hot rolled, rolled,...
5.1 This practice is used to provide steel phase transformation data required for use in numerical models for the prediction of microstructures, properties, and distortion during steel manufacturing, forging, casting, heat treatment, and welding. Alternatively, the practice provides end users of...
This specification covers the requirements for seamless UNS C10200, C12000, or C12200 copper alloy tubes used for connection, repairs, or alternations of field air conditioning or refrigeration units. Materials in the form of billets, bars, or tubes should be used to produce a homogeneous uniform...
This specification establishes the requirements for seamless copper and copper alloy tubing on which the external or internal surface, or both, has been modified by a coldforming process to produce an integral enhanced surface for improved heat transfer. The tubes are typically used in surface...
This specification covers general requirements that shall apply to stainless wire and wire rods. Wire is intended primarily for cold forming, including coiling, stranding, weaving, heading and machining as covered under the required specifications. The material may be furnished in one of the...
1.1 This specification2 covers a group of common requirements that, unless otherwise specified in the individual product specification, shall apply to steel forgings under any of the following specifications issued by ASTM: ASTM Designation Title A266/A266M Carbon Steel Forgings for Pressure Vessel...
5.1 This test method is used to assess in situ strength of undisturbed soil and compacted materials (or both). The penetration rate of the 8 kg [17.6 lb] DCP can be used to estimate in situ CBR (California Bearing Ratio), to identify strata thickness, shear strength of strata, and other material...
This guide covers a group of requirements for carbon and alloy steel bars under each of the following specifications: hot-rolled carbon steel bars, cold-finished carbon steel bars, hot-rolled alloy steel bars, and cold-finished alloy steel bars. Heat and product analysis shall be performed on...
This specification covers nickel-alloy steel plates intended primarily for welded pressure vessels. As a steel making practice, the steel shall be killed and shall conform to fine grain size requirements. The heat treatment requirements for all plates are presented, and all plates under...
1.1 This test method is for the determination of total sulfur in combustible fuel gases, when present in sulfur concentrations between approximately 25 and 700 mg/m3 (1 to 30 grains per 100 cubic feet). It is applicable to natural gases, manufactured gases, mixed gases, and other...
This specification covers the requirements for quenched and tempered alloy steel hexagon socket button (SBHCS) and flat countersunk (SFHCS) head cap screws. The screws shall be fabricated from alloy steel made to fine grain practice. The chemical composition of the screw material shall...
5.1 Fracture toughness is expressed in terms of an elastic-plastic stress intensity factor, KJc, that is derived from the J-integral calculated at fracture. 5.2 Ferritic steels are microscopically inhomogeneous with respect to the orientation of individual grains. Also, grain...
5.1 Fatigue crack growth rate expressed as a function of crack-tip stress-intensity factor range, da/dN versus ?K, characterizes a material's resistance to stable crack extension under cyclic loading. Background information on the ration-ale for employing linear elastic fracture mechanics to...
