444444不銹鋼是一種超低碳氮、含18%鉻與2%鉬、高耐蝕的鐵素體不銹鋼。該鋼種一般采用鈮或鈦進(jìn)行穩(wěn)定化，可以避免焊接后的晶間腐蝕。該鋼種特別適合應(yīng)用于各種水處理裝置。444的屈服強(qiáng)度相當(dāng)于碳素鋼的1.5倍，玻璃鋼的6倍，對(duì)于耐震，耐積雪，耐風(fēng)壓，耐沖擊等具有出類拔萃的優(yōu)良性。444鐵素體不銹鋼導(dǎo)熱系數(shù)高，約為鉻鎳奧氏體不銹鋼的130%～150%,非常適合熱交換的用途．熱膨脹系數(shù)小，小分隊(duì)僅為鉻鎳奧運(yùn)氏體不銹鋼的60%～70%,非常適合熱漲，冷縮，有熱循環(huán)的條件下使用．該鋼種的塑性，韌性較好，適于拉伸，軋制成型和沖壓制造．特別是耐應(yīng)用腐蝕是最優(yōu)異的，在高的氯化物介質(zhì)中耐蝕性能優(yōu)于普通鐵素體不銹鋼和奧運(yùn)會(huì)氏體不銹鋼，一般不產(chǎn)生氯化物的應(yīng)力腐蝕破裂．在加入Ti,Mo等元后，提高了耐孔蝕和縫隙腐蝕的性能．該鋼種可采用焊接普通不銹鋼的方法焊接．該鋼種特別適合于食品加工設(shè)備，熱交換器,熱水器罐,蓄水槽,太陽(yáng)能收集面板等.444鋼種屬于高合金鐵素體不銹鋼，與常用鋼種SUS430相比：1. 含鉻量高1.0%左右，且添加了合金元素鉬（Mo），因此該鋼種具有良好的耐點(diǎn)蝕、縫隙腐蝕、應(yīng)力腐蝕能力，其耐蝕能力在某些領(lǐng)域甚至優(yōu)于SUS304和SUS316。2. 添加了鈦（Ti），鈮（Nb），鋯（Zr）等穩(wěn)定化元素，因此該鋼種具有良好的耐晶間腐蝕和耐高溫氧化性能。 PRODUCT PARAMETERS 產(chǎn)品參數(shù)
