Overview
ISO 13583-1:2023 - "Centrifugally cast steel and alloy products - Part 1: General testing and tolerances" specifies general requirements, test methods and tolerances for horizontal and vertical centrifugally cast steel and alloy products intended for heat-resisting, corrosion-resisting and general engineering applications. The standard sets expectations for supply, mechanical testing, surface finish, minimum sound wall (MSW) thickness, dimensional and shape tolerances, inspection procedures and optional supplementary tests.
Key topics and requirements
- Scope and materials: Materials are to be specified by the purchaser; products must conform to ISO 4990 delivery requirements.
- Mechanical tests: Tensile tests follow ISO 6892-1 (room temperature) or ISO 6892-2 (elevated temperature) when agreed. Test pieces may be taken from castings or separately cast samples from the same melt if agreed.
- Minimum sound wall (MSW): MSW defines the net thickness after removing surface porosity/roughness; measurement methods and tolerances must be agreed. MSW measurements are taken at 90° intervals.
- Dimensional tolerances: Default tolerances apply unless purchaser specifies otherwise. Examples from the standard include:
- Length tolerances: ≤150 mm: +4/0 mm; >150 mm: +5/0 mm.
- Outside diameter as-cast tolerances: e.g., ≤150 mm: +2/0 mm; >1 000 mm: +8/0 mm.
- Machined surface defaults (if not specified): outside diameter tolerance +1.5/0 mm; inside diameter tolerance 0/−1.5 mm.
- Inspection and acceptance: Visual examination of as-cast outside surfaces; cracks are unacceptable. Dye penetrant (ISO 4987) and magnetic particle testing (ISO 4986) are referenced for defect verification. Acceptance severity levels for penetrant inspection are specified unless otherwise agreed.
- Supplementary tests: Purchaser can require pressure tests (ISO 4990), acid etch ring tests, ferrite determination (ISO 13520), corrosion tests (ISO 3651-1/2), eddy current, radiography (ISO 4993) and ultrasonic testing (ISO 4992-1/2).
Applications and intended users
- Typical users: foundries, centrifugal casting manufacturers, procurement/specification engineers, quality/inspection teams, fabricators and end-users in power generation, petrochemical, chemical processing and heavy engineering.
- Practical use: specifying MSW, agreed inspection regimes, defining mechanical test options, and embedding acceptable dimensional tolerances into purchase orders and quality plans for centrifugally cast components.
