裝飾管1.4313是馬氏體級，耐耐灼傷性高，熱治理 后耐用性好。X3CrNiMo13-4鋼的機耐灼傷性是因為化學上組成成分中鉬和鎳的高份量。這個合金材料加上劑上限了提升級碳份量的是需要——給定濃硫酸濃度等同于于奧氏體裝飾管。一般鎳份量不夠，但鎳份量約為4%，強勢從而提高了鋼對多種耐灼傷性區域的抗拒力——三次機耐灼傷性。X3CrNiMo13-4鋼用戶賬戶可種植可高達300℃在溫濕度下上班的鑄件和鑄件，與表露在多種耐灼傷性區域中的鑄件，時長期保持足夠的的表皮生活必要條件括抗氯化物特性)。QT650.QT780和QT900生活必要條件下，熱治理 后最應托付鋼材。半制成品采用頁巖油種植.化學工業.在冶金這個行業和電力能源這個行業，增壓機表露在高和氣底溫下.泵.解空調壓縮機元器件。鋼不能適用合電弧焊接。
