Basic Information
Scope
Scope: This document specifies the grades and designation methods, basic requirements, technical requirements, test methods, inspection rules, marking and quality certificates, anti-rust measures, packaging, storage, and transportation of heat-resistant low-alloy ferritic nodular cast iron parts. This document applies to heat-resistant low-alloy ferritic nodular cast iron parts cast in sand molds or molds with similar thermal conductivity to sand molds, with a silicon (Si) content of 2.3% to 5.2% and a molybdenum (Mo) content of 0.4% to 1.1%, and an operating temperature of less than 500°C. Main technical content: This document specifies the grades and designation methods, basic requirements, technical requirements, test methods, inspection rules, marking and quality certificates, anti-rust measures, packaging, storage, and transportation of heat-resistant low-alloy ferritic nodular cast iron parts.
