Preface: Instead of this standard GB/T9437-1988 "heat resisting cast iron pieces. Compared this standard with GB/T9437-1988, the main technical content changes as follows: - changes the heat-resisting cast iron brand representation; - changes the heat resistant cast iron in chemical component content of P and S elements; - increase the Q TRSi4Mo1 brand and its corresponding chemical composition and mechanical properties at room temperature; - changes the heat-resisting cast iron oxidation test duration of points; - increases the appendix F test method for thermal expansion coefficient. The appendix A of this international standard, appendix B, appendix C, appendix D, appendix E and appendix F are informative appendices. this Standard put forward by China machinery industry federation. This standard cast by the national standardization technical committee (SAC/TC54) under centralized. This standard drafting unit: shenyang institute of foundry, maanshan double xin wear-resisting material co., LTD, maanshan Haitian heavy industry science and technology development co., LTD., xixia county of internal combustion engine into the exhaust pipe co., LTD The company, Shanghai institute of materials. Main drafter of this standard: Zhang Yin, aqua li ai-min sun, xin-wu zhao, Winston, l., &yang, Zhang Honghe. This standard replaced all previous releases of standard: GB/T9437-1988.
Description:This standard stimulates the heat-resisting cast iron pieces of technical requirements, test methods, inspection rule, mark and quality certificate, rust, packaging and storage requirements.
this standard applies to the sand mold casting or thermal conductivity as a sand mold casting in pouring into and working under 1100 ℃ heat resisting cast iron pieces.
