ASTM A255-20a 确定钢硬化性的标准试验方法

1.1 These test methods cover the identification and description of test methods for determining the hardenability of steels. The two test methods include the quantitative end-quench or Jominy Test and a method for calculating the hardenability of steel from the chemical composition based on the original work by M. A. Grossman. 1.2 The selection of the test method to be used for determining the hardenability of a given steel shall be agreed upon between the supplier and user. The Certified Material Test Report shall state the method of hardenability determination. 1.3 The calculation method described in these test methods is applicable only to the range of chemical compositions that follow: Element Range, % Carbon 0.10–0.70 Manganese 0.50–1.65 Silicon 0.15–0.60 Nickel 1.50 max Chromium 1.35 max Molybdenum 0.55 max Copper 0.35 max Vanadium 0.20 max 1.4 Hardenability is a measure of the depth to which steel will harden when quenched from its austenitizing temperature (Table 1). It is measured quantitatively, usually by noting the extent or depth of hardening of a standard size and shape of test specimen in a standardized quench. In the end-quench test the depth of hardening is the distance along the specimen from the quenched end which correlates to a given hardness level. 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 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.

Standard Test Methods for Determining Hardenability of Steel

ASTM E3039-20 用DWTT型试样测定铁素体钢裂纹尖端张开角的标准试验方法

1.1 This test method covers the determination of fracture propagation toughness in terms of the steady-state crack-tipopening angle (CTOA) using the drop-weight tear test (DWTT)-type specimen. The method is applicable to ferritic steels that exhibit predominantly ductile fracture with at least 85 % shear area measured according to Test Method E436 Standard Test Method for Drop-Weight Tear Tests of Ferritic Steels. This test method applies to ferritic steels with thicknesses between 6 mm and 20 mm. Annex A1 describes the method to test ferritic steels with thicknesses between 20 mm to 32 mm. 1.2 In terms of apparatus, specimen design, and test methodology, this test method draws from Test Method E436 and API 5L3 Recommended Practice for Conducting DropWeight Tear Tests on Line Pipe. 1.3 The development of this test method has been driven by the need to design for fast ductile fracture arrest of axial running cracks in steel high-pressure gas pipelines (1). 2 The purpose has been to develop a test to characterize fracture propagation resistance in a form suitable for use as a pipe mill test (2). The traditional Charpy test has been shown to be inadequate for modern high toughness pipe steels (1). This test method measures fracture propagation resistance in terms of crack-tip opening angle, and is used to characterize ferritic steels. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. 1.6 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.

ASTM A710/A710M-19 降水量标准规范&x2013；强化低碳镍铜铬钼铌（铌）合金结构钢板

1.1 This specification covers low-carbon precipitation — strengthened nickel copper chromium molybdenum columbium (niobium) alloy steel plates for general applications. The alloys in this specification are strengthened by precipitation in various temperature ranges. Precipitation strengthening can occur upon air cooling after hot rolling, during normalizing, and by another heat treatment. These grades are not intended for use in applications above 900°F [480°C]. 1.2 Two grades, each with three classes, are provided as follows: Grade and Class Condition Grade A, Class 1 as-rolled and precipitation heat treated Grade A, Class 2 normalized and precipitation heat treated Grade A, Class 3 quenched and precipitation heat treated Grade B, Class 1 as-rolled Grade B, Class 2 normalized Grade B, Class 3 normalized and precipitation heat treated 1.3 Grade A provides minimum yield strength levels ranging from 50 to 85 ksi [345 to 585 MPa], depending on thickness and condition. 1.4 Grade A, Class 1, plates are limited to a maximum thickness of 3⁄4 in. [20 mm]. The maximum thickness of Grade A, Classes 2 and 3, is limited only by the capacity of the composition to meet the specified mechanical property requirements; however, current practice normally limits the maximum thickness to 8 in. [200 mm]. 1.5 Mandatory notch toughness requirements are specified for Grade A, Class 1. 1.6 Grade B provides minimum yield strength levels ranging from 70 to 75 ksi [485 to 515 MPa], depending on thickness and condition. 1.7 Grade B plates are limited to a maximum thickness of 2 in. [50 mm]. 1.8 Mandatory notch toughness requirements are specified for the three classes of Grade B. 1.9 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized. See Appendix X3 of Specification A6/A6M for information on weldability. 1.10 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.11 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.
