scope:

This document provides recommended practices for batch-type heat treatment, continuous-type heat treatment, and processing of qualification testing coupons for carbon, micro-alloyed, and low-alloy steel wrought and cast components.

This recommended practice is intended:

- for use on components being manufactured for conformance to API product specifications or standards; and

- to supplement the heat treatment and testing requirements found in the API product specifications or standards.

Batch and continuous heat treatment and testing of hot isostatically pressed products or additively manufactured metallic products are outside the scope of this RP.
