Overview

ISO 13583-2:2023 - "Centrifugally cast steel and alloy products - Part 2: Heat‑resistant materials" specifies cast steel and nickel‑alloy grades intended for elevated‑temperature service produced by centrifugal casting. The third edition (2023) is a minor editorial revision and forms part of the ISO 13583 series. Its scope covers the chemical compositions, mechanical properties and short‑time rupture/creep data needed to select and supply heat‑resistant centrifugally cast components.

Key topics and requirements

• Scope and conformity: Grades in this document must conform to the general delivery requirements of ISO 4990 and the testing/tolerance rules in ISO 13583‑1.
• Chemical composition: Table 1 lists mass‑fraction limits for carbon, silicon, manganese, chromium, nickel, molybdenum, niobium, tungsten, cobalt and other micro‑alloying elements for each ISO grade (e.g., GX25CrNiSi18‑9, GX40NiCrSi38‑19, G‑NiCr28W).
• Mechanical properties: Room‑temperature requirements (yield, tensile strength, elongation) are provided in Table 2; short‑time rupture (minimum rupture time at specified stress and temperature) is in Table 3.
• Creep and long‑term data: Annex A gives mean values for 1% elongation and creep rupture strengths for 10 000 h and 100 000 h at various temperatures - critical for high‑temperature design.
• Physical properties: Annex B provides density, specific heat, thermal conductivity and thermal expansion values to support thermal analyses.
• UNS equivalents: Annex C maps ISO cast grades to similar UNS cast grade numbers for cross‑referencing.
• Heat treatment & testing: Heat treatment is not required by default; if needed it must be agreed in the purchase contract. Mechanical testing at room and elevated temperatures is carried out when agreed between manufacturer and purchaser.
• Supplementary requirements: Optional clauses from ISO 4990 and ISO 13583‑1 can be applied by agreement.

Applications and who uses it

ISO 13583‑2 is used by:

• Foundries and centrifugal casting manufacturers specifying heat‑resistant castings
• Materials and design engineers selecting high‑temperature alloys for components
• Procurement and quality teams creating purchase orders and inspection plans
• OEMs and maintenance teams in industries requiring elevated‑temperature components (power generation, petrochemical, metallurgy and process industries) Typical uses include any centrifugally cast component intended for prolonged high‑temperature service where creep, rupture and thermal properties are critical.

Related standards

• ISO 4990 - Steel castings: general delivery requirements
• ISO 13583‑1 - Centrifugally cast steel and alloy products: general testing and tolerances
• EN 10027 series - steel designation rules (referenced for naming/numbering)

Keywords: ISO 13583‑2:2023, centrifugally cast, heat‑resistant materials, cast steel, nickel alloys, elevated temperature service, creep rupture, mechanical properties.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
