        碳鋼鑄件應(yīng)用在鑄鋼制造氣動(dòng)調(diào)節(jié)閥閥體和閥蓋的情況很廣泛,按國(guó)家標(biāo)準(zhǔn)9277-73(德?tīng)柟S什德工廠擬訂的)所規(guī)定的機(jī)械特性、鑄造特性、穩(wěn)定性等等,經(jīng)常使用的鋼OTA20相當(dāng)于GS-C25 ( DIN17245或ASTM-A215-58)。它的使用壓力≥6巴,溫度接近于400攝氏度.而合金鋼被用來(lái)制造工作于高溫或低溫狀態(tài)(非強(qiáng)腐.蝕性介質(zhì))的閥體(蓋)。不同材料在調(diào)節(jié)閥的用處各有不同。
