T/CFA 020101243-2021 Isothermal quenching of ductile iron parts
Basic Information
Scope
Scope: This document specifies the terms and definitions of isothermal quenched nodular cast iron parts, the method of indicating grades, production methods and chemical compositions, technical requirements, sampling, inspection methods, inspection rules, marking and quality certificates, anti-rust, packaging, storage and transportation requirements. This document is applicable to isothermal quenched nodular cast iron parts cast in sand molds or molds with thermal conductivity equivalent to sand molds. For isothermal quenched nodular cast iron parts produced by other casting processes (such as metal molds, sand-coated molds, shell molds, investment casting, and continuous casting), reference may be made to this document. Main technical content: This document specifies the terms and definitions of isothermal quenched nodular cast iron parts, the method of indicating grades, production methods and chemical compositions, technical requirements, sampling, inspection methods, inspection rules, marking and quality certificates, anti-rust, packaging, storage and transportation requirements.
