ASTM B912-02 用电抛光法测定不锈钢钝化的标准规范

1.1 This specification covers the passivation of stainless steel alloys in the 200 (UNS2XXXX), 300 (UNS3XXXX), and 400 (UNS4XXXX) series, and the precipitation-hardened alloys, using electropolishing procedures.Note 18212;Surface passivation occurs simultaneously with electropolishing under proper operating conditions. The quality of passivation will depend on the type of stainless steel, the formulation of the electropolishing solution, and the conditions of operation. Free iron on the surface of the stainless steel is removed resulting in improved corrosion resistance. Surface smoothing obtained by electropolishing will also improve corrosion resistance. Electropolishing will also remove heat tint and oxide scale.1.2 This specification may involve hazardous materials, operations, and equipment. This specification 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM B796-02 低合金粉末锻钢部件的非金属杂质含量的标准测试方法

The extensive porosity present in pressed and sintered ferrous materials masks the effect of inclusions on mechanical properties. In contrast, the properties of material powder forged to near full density are strongly influenced by the composition, size, size distribution, and location of nonmetallic inclusions. The test for nonmetallic inclusions in powder forged steels is useful as the following: 4.2.1 Characteristic to classify or differentiate one grade of powder from another. 4.2.2 Means of quality comparison of powders intended for powder forging, lot to lot. Significant variations in nonmetallic inclusion content will occur if: 4.3.1 The powder used to form the test specimen does not meet powder forging quality standards for nonmetallic inclusion content. 4.3.2 Processing of the powder forged test specimen has been carried out under conditions that do not permit oxide reduction or allow oxidation of the test specimen, or both.1.1 This test method covers a metallographic method for determining the nonmetallic inclusion level of powders intended for powder forging (P/F) applications.1.2 The test method covers repress powder forged test specimens in which there has been minimal lateral material flow ( < 1%). The core region of the powder forged test specimen shall contain no porosity detectable at 100.1.3 This test method is not suitable for determining the nonmetallic inclusion level of powder forged test specimens that have been forged such that the core region contains porosity. At the magnification used for this test method residual porosity is hard to distinguish from oxide inclusions. Too much residual porosity makes a meaningful assessment of the inclusion population impossible.1.4 The test method may be applied to materials that contain manganese sulfide (admixed or prealloyed) provided the near neighbor separation distance is changed from 30 956;m to 15 956;m.Note 18212;The test method may be applied to powder forged parts where there has been a greater amount of material flow provided:The near neighbor separation distance is changed, or The inclusion sizes agreed between the parties are adjusted for the amount of material flow.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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM A181/A181M-01 通用管道的碳素钢锻件用标准规范

1.1 This specification covers nonstandard as-forged fittings, valve components, and parts for general service. Forgings made to this specification are limited to a maximum weight of 10 000 lb [4540 kg]. Larger forgings may be ordered to Specification A266/A266M. 1.2 Two grades of material are covered, designated as Classes 60 and 70, respectively, and are classified in accordance with their chemical composition and mechanical properties as specified in 5.1 and 6.1. 1.3 Class 60 was formerly designated Grade I and Class 70 was formerly designated Grade II. 1.4 This specification is expressed in both inch-pound units and SI units.

ASTM E768-99(2005) 钢的自动杂质评定用试样的制备和评价标准指南

Inclusion ratings done either manually using Test Methods E 45 or automatically using Practice E 1122 or E 1245 are influenced by the quality of specimen preparation. This guide provides examples of proven specimen preparation methods that retain inclusions in polished steel specimens. This guide provides a procedure to determine if the prepared specimens are of suitable quality for subsequent rating of inclusions. None of these methods should be construed as defining or establishing specific procedures or limits of acceptability for any steel grade.1.1 This guide178 covers two preparation methods for steel metallographic specimens that will be analyzed for nonmetallic inclusions with automatic image analysis (AIA) equipment. The two methods of preparation are offered as accepted methods used to retain nonmetallic inclusions in steel. This guide does not limit the user to these methods.1.2 A procedure to test the suitability of the prepared specimen for AIA inclusion work, using differential interference contrast (DIC), is presented.

ASTM B777-99 钨基高密度金属标准规范

1.1 This specification covers the requirements for four classes of machinable, high-density tungsten base metal produced by consolidation of metal powder mixtures of which the composition is mainly tungsten. This material specification may be used for bare parts or be used for parts that may be coated with other materials for protection against corrosion and abrasion. 1.2 Intended Use -Parts made from this material are intended for uses such as weights or counter-balances in static or dynamic balancing high-speed rotating inertia members, radiation shielding, hypervelocity impact, and vibration-damping applications. 1.3 Special Applications -For particular applications, properties or requirements other than those specified in Section 6 of this specification may be important. These alloys may contain elements which make them magnetic. Where freedom from magnetic response is required, this should be specified in the purchase order. Class 4 is not available in a non-magnetic grade. For purposes of this specification, non-magnetic characteristics are defined as material having a maximum magnetic permeability of 1.05 (see Test Method B193). Also for special applications involving large sections, methods for determining internal quality, such as mechanical tests on specimens from these larger sections or suitable nondestructive tests may be applied. If required, these additional tests shall be specified in the purchase order. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

ASTM B242-99 电镀用高碳钢制备的标准实施规范

1.1 This practice is intended as an aid in establishing and maintaining a preparatory cycle for electroplating on high-carbon steel (Note 1) producing a minimum of hydrogen embrittlement and maximum adhesion of the electrodeposited metal. For the purpose of this practice, steels containing 0.35% of carbon or more, and case-hardened low-carbon steel, are defined as high-carbon steels. There is no generally recognized definite carbon content dividing high- from low-carbon steels for electroplating purposes. Note 1-Electroplating of plain high-carbon steel introduced problems not found in similar operations on low-carbon steel. During the cleaning and electroplating cycle, high-carbon steel differs from low-carbon steel in regard to its greater tendency to become embrittled and the greater difficulty in obtaining maximum adhesion of the electrodeposit. The preparation of low-carbon steel for electroplating is covered in Practice B183. 1.2 This practice does not apply to the electroplating of alloy steel. For methods of chromium electroplating directly on steel see Practice B177. 1.3 This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazards statement, see 3.1.
