產(chǎn)品簡介 / Introduction

2304不銹鋼鋼（中國牌號：00Cr23Ni4N)是瑞典開發(fā)的一個低合金的雙相不銹鋼，它固溶處理溫度為1000℃左右，組織有40%-50%鐵素體和50%-60%奧氏體，具有雙相不銹鋼的共性特點，是作為一個具有高強度和價廉特色，能代替304L和316L常用奧氏體不銹鋼而開發(fā)的鋼種。

它已被美國機械工程協(xié)會（ASME）確認可用于鍋爐和壓力容器、化工廠和煉油廠的管道，不少國家已納入標準。美國標準為UNS S32304 ，瑞典的商業(yè)牌號為 SAF 2304。

化學成分：

UNS 2304牌號 C ≤ 0.030 、 Si ≤ 1.0 、 Mn ≤ 2.5 、 S ≤ 0.030 、 P ≤ 0.040 、 Cr: 21.5 - 24.5 、 Ni: 3.0 - 5.5 、 Mo: 0.05 - 0.6 、N: 0.05 - 0.20 、 Cu：0.05 - 0.6
