不繡鋼圓管1.4313是馬氏體級，耐灼傷高朝，熱操作后耐用性好。X3CrNiMo13-4鋼的機制特點是致使生物組成成分中鉬和鎳的高純度。此類合金鋼生成劑禁止了增長級碳純度的必須——給定溶液濃度很多于奧氏體不繡鋼圓管。盡管鎳純度不太高，但鎳純度約為4%，為顯著提供了鋼對種種灼傷自然的環境的抗御力——再次機制特點。X3CrNiMo13-4鋼用戶組可工作任務達300℃在溫暖下工作任務的元器件和元器件，甚至表露在種種灼傷自然的環境中的元器件，另外提高足夠了的接觸面能力括抗氯化物物理性質)。QT650.QT780和QT900能力下，熱操作后最先竣工H型鋼。半現做用在中國石油工作任務.化工品.在冶金工程和能源系統業，渦輪機機表露在高溫和性環境溫度下.泵.文件壓宿機部位。鋼不舒符合熔接。
