    310S不銹鋼無縫管可以耐高溫
    310S,俗稱2520,由于CR含量指標為25,NI含量指標為20,故稱2520.
    310S是奧氏體鉻鎳不銹鋼具有很好的抗氧化性、耐腐蝕性,因為較高百分比的鉻和鎳,310S擁有好得多蠕變強度,在高溫下能持續作業,具有良好的耐高溫性。
    310S不銹鋼(2520)耐高溫鋼管; 310S因鎳(Ni)、鉻(Cr)含量高,具有良好耐氧化、耐腐蝕、耐酸咸、耐高溫性能,耐高溫鋼管專用于制造電熱爐管等場合,奧氏體型不銹鋼中增加碳的含量后,由于其固溶強化作用使強度得到提高,奧氏體型不銹鋼的化學成分特性是以鉻、鎳為基礎添加鉬、鎢、鈮和鈦等元素,由于其組織為面心立方結構,因而在高溫下有高的強度和蠕變強度。
    310S相關產品有,310S不銹鋼棒,310S不銹鋼板,310S不銹鋼管,310S不銹鋼線(特殊用材),等相關耐高溫系列鋼材,
    化學成份:
    C :≤0.08, Si :≤1.00, Mn :≤2.00, P :≤0.035, S :≤0.030, Ni :≤19.00-22.00,
    Cr :≤24.00-26.00
    力學性能:
    硬度(HB) :≤187
    抗拉強度(бb)(Mpa) :≥520
    屈服強度(σs)(Mpa) :≥205
    伸長率(δ)% :≥40

    面積縮減(ψ)% :≥50
