This specification establishes the requirements for additive manufacturing of stainless steel alloy (UNS S31603) components by means of laser and electron beam-based full melt powder bed fusion processes. The components produced by these processes are typically used in applications that require mechanical properties similar to machined forgings and wrought products. Components manufactured to this specification are often, but not necessarily, post processed via machining, grinding, electrical discharge machining (EDM), polishing, and so forth to achieve desired surface finish and critical dimensions.1.1 This specification covers additive manufacturing of UNS S31603 components by means of laser and electron beam-based full melt powder bed fusion processes.

This specification covers the standard for stainless and heat-resisting chromium-nickel steel plate, sheet, and strip. The steel shall conform to the requirements as to chemical composition in carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, and molybdenum. The material shall also conform to the mechanical properties such as tensile strength, yield strength, elongation, and hardness.1.1 This specification covers stainless and heat-resisting chromium-nickel steel plate, sheet, and strip.1.2 The values stated in inch-pound units are to be regarded as the standard.Note 1—Grades that were previously covered in both Specifications A 167 and A 240/A 240M have been removed from this specification and may now be supplied and purchased in compliance with Specification A 240/A 240M. The chemical and mechanical property requirements of these grades were identical in Specifications A 167 and A 240/A 240M at the time of removal from Specification A 167.

This specification covers age-hardening stainless steel forgings for general use. Materials for forgings shall consist of billets or bars and shall either be forged, rolled, or cast or a section cut from an ingot. The steel specimens shall be solution annealed and age hardened and shall conform to the required values of tensile strength, yield strength, elongation, reduction of area, hardness and impact Charpy-V. The steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, aluminum, molybdenum, titanium, copper, nitrogen, columbium, and tantalum.1.1 This specification2 covers age-hardening stainless steel forgings for general use.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.3 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.NOTE 1: Bar products are covered by Specification A564/A564M.1.4 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.1.5 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.

4.1 Insulations that are used as a part of the thermal insulation system in contact with austenitic stainless steels have the potential to become contaminated with water soluble corrosive ions which, in turn, if permitted to reach the stainless steel surface, are possible to contribute to external stress corrosion cracking (ESCC). Therefore, it is important to reduce the exposure of such insulating materials to water-soluble corrosive ion compounds at all stages of manufacture, handling, shipping, storage, and application. During manufacture, precautions shall be taken to minimize water soluble corrosive ion content, both in the material and as surface contamination. Once the manufacture is complete, care must be exercised during handling, transporting, shipping, storage, receiving, and application to avoid contamination with corrosive ions that can be transported by water through the insulation materials onto the stainless steel surface. This practice presents criteria which, if followed, will minimize the risks of ESCC associated with the application of insulation materials. It must be emphasized, however, that because of the many variable factors present, complete freedom from ESCC can not be assured under all circumstances, even when following the guidance of this practice.4.2 Continued protection of the insulation and the stainless steel surface from moisture and contamination after the insulation system is installed and over its entire service life is of significant importance. In-service contamination has the potential to occur from many sources; for example, from airborne contaminates, rain or salt spray, periodic fire sprinkler system tests, wash-downs, or process leakage. Weather barrier jacketing systems and proper application shall be chosen to provide long-term protection in the intended use environment.4.3 The entire insulation system shall be periodically inspected and maintained. Insulation that is suspected of contamination shall be retested or immediately replaced. Wash down of insulated pipe and equipment shall be avoided. Whenever possible, protective coatings or finishes shall be applied directly to the stainless steel surface as the primary source of corrosion protection.1.1 This practice is intended to provide guidance and direction in the handling, transporting, shipping, storage, receiving, and application of thermal insulating materials to be used as a surface treatment or as part of the thermal insulation system in contact with austenitic stainless steel.1.2 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.1.3 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.

This specification covers stainless steel forgings for compressor and turbine bucket, blade, and airfoil applications. The stainless steel shall be made by the melting process and either the closed impression die or the open die forging processes may be utilized. Two complete heat treatments, consisting of an austenize, quench, and temper, are permitted. When heat treatment for mechanical properties is followed by straightening, a stress-relieving heat treatment is required. The forgings shall be subjected to tension, impact, hardness, and non-destructive tests. All forgings shall be free of cracks, seams, laps, shrinkage, and similar discontinuities.1.1 This specification covers stainless steel forgings for compressor and turbine bucket, blade, and airfoil applications.1.2 This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M designation (SI units), the inch-pound units shall apply. 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 necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.1.3 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.
