Introduction

GB/T 47574 "Centrifugal Cast Steel and Alloy Castings" adopts the international standard ISO 13583 "Centrifugal Cast Steel and Alloy Castings" and is consistent with...

Maintaining consistency with international standards will guide my country's production of centrifugal cast steel and alloy castings to reach international technological levels, thereby ensuring product consistency.

The quality and stability of castings will enhance the recognition of Chinese casting products in the international market.

GB/T 47574 aims to establish test methods, tolerances, and general requirements for heat-resistant material grades applicable to centrifugally cast steel and alloy castings.

It consists of two parts.

---Part 1: General Tests and Tolerances. The aim is to provide general testing and tolerances applicable to centrifugal cast steel and alloy castings produced in both horizontal and vertical environments.

General test methods and tolerance requirements.

---Part 2: Heat-resistant materials. The purpose is to specify the requirements for cast steel and nickel-based alloys used in high-temperature service products manufactured using centrifugal casting processes.

Grade, alloy composition and mechanical property requirements.
