ASTM A 1100 : 2016 : R2022

1.1This guide covers the process control and product properties verification of continuous heat treating of material using a quench and temper induction process (surface hardening, surface heat treating, and batch heat-treated products using induction are not considered in this guide). Examples of products covered by this guide may include products covered by API Specifications 20E, 5L, and 5CT.

1.2This guide indicates some features of induction heat treating compared to furnace heat treating. Induction heat treating processes typically operate at higher temperatures compared to furnace processes.

1.3This guide addresses the features and requirements necessary for induction heating and ancillary equipment. However, induction equipment may be used in combination with convection heating equipment (for example, gas or electric furnaces).

1.4Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.5This 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.

1.6This 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.
