This specification covers two chromium-iron alloys, one is UNS K91800 with nominally 18% chromium, balance iron, and the other is UNS K92801 with nominally 28% chromium, both in strip, bar, wire, and rod forms intended primarily for sealing to glass in electronic applications. The alloys are classified by nominal chemical composition, specifically by chromium content, in two types: Type I (UNS K91800) and Type II (UNS K92801). The materials shall show no evidence of transformation to martensite. For Type I alloy, the austenite formed during heat treating will transform to martensite at or above room temperature. The presence of austenite, as may be noted in Type II alloy, is acceptable if the thermal expansion requirement is met. Different tests shall be performed in order to determine the following properties of the alloys: thermal expansion, Rockwell hardness, and tensile strength.1.1 This specification covers two chromium-iron alloys, the former, (UNS K91800), nominally 18 % chromium, balance iron, the latter, (UNS K92801), nominally 28 % chromium, in strip, bar, wire, and rod forms intended primarily for sealing to glass in electronic applications.NOTE 1: UNS K92801 should only be considered for use at service temperatures below 300°C. The alloy is prone to sigma phase formation at temperatures close to 620°C, and exhibits brittle mechanical behavior after prolonged exposures at temperatures close to 475°C.1.2 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.1.3 The following hazard caveat pertains only to the test method portion, Sections 16 and 17, of this specification. 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.1.4 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.

ASTM B597-92(1998) Standard Practice for Heat Treatment of Aluminum Alloys (Withdrawn 2002) Withdrawn, Replaced 发布日期 :  1970-01-01 实施日期 : 

1.1 This practice is intended as an aid in establishing a suitable procedure for the heat treatment of aluminum alloys. 1.2 Times and temperatures appearing in the heat treatment tables are typical for various forms, sizes, and manufacturing methods and may not provide the optimum heat treatment for a specific item. 1.3 Some alloys in the 6XXX series may achieve the T4 temper by quenching from within the solution temperature range during or immediately following a hot working process, such as upon emerging from an extrusion die. Such alternatives to furnace heating and immersion quenching are indicated by footnote O, of the table for heat treatment of wrought aluminum alloys. However, this practice does not cover the requirements for a controlled press heat treatment. (A practice for press solution heat treatment of aluminum alloys is being developed.)

5.1 This practice may be used for approximating a limiting design stress at room temperature and, in some cases, for approximating the range of elastic behavior. Elastic limit, or the greatest stress that a material is capable of sustaining without any permanent strain remaining upon complete release of the stress, is a more technically accurate design parameter; however, the elastic limit is extremely difficult to measure in routine testing. Caution should be used in applying such values to predict the behavior of flat or wire springs in bending, torsion or other stress modes, or at temperatures other than that at which the determination is made.1.1 This practice establishes the requirements for determining offset yield strength (0.01 %, 0.02 %, and 0.05 % offset) at room temperature. It is intended for copper alloys in tempers commonly used for spring applications, and materials thicker than 0.010 in. (0.25 mm).1.1.1 The primary application of this practice is intended for flat strip materials that are used for springs; however, this practice can be used for other product forms, such as wire, rod, and bar.1.2 Units—Values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.1.3 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.
