江蘇蘇州倍徠斯金屬供應(yīng)東北特鋼18Cr2Ni4WA圓鋼價(jià)格,大冶特鋼18Cr2Ni4WA合金工具鋼,上海寶鋼18Cr2Ni4WA是什么材料?無錫-蘇州18Cr2Ni4WA供應(yīng)商。銷售18Cr2Ni4WA圓棒,批發(fā),零售,切割等!
18Cr2Ni4WA屬于高強(qiáng)度中合金滲碳鋼。要使C化物及奧氏體含量不超標(biāo)可采用滲碳后高溫回火900~920℃滲碳,600~650回火,深冷處理,油淬后的硬度也就是48左右,想要達(dá)到HRC58-63,必須要進(jìn)行表面滲碳。
18Cr2Ni4WA鋼常用合金滲碳鋼,強(qiáng)度,韌性高,淬透性良好,也可在不滲碳而調(diào)質(zhì)的情況下使用,一般用做截面較大,載荷較高且韌性良好,缺口敏感性低的重要零件。18Cr2Ni4WA belongs to high strength medium alloy carburizing steel. To make C materialized and austenite content does not exceed the standard can adopt carburizing after high temperature tempering 900~920 DEG C carburizing, 600-650 tempering, cryogenic treatment, after oil quenching hardness also is 48%, want to achieve HRC58-63, must to the carburizing surface.
18Cr2Ni4WA Steel commonly used alloy carburizing steel, strength, high toughness, quenching of good, also can be in carburization and quenching and tempering, the general use of do larger sections and higher load and good toughness and low notch sensitivity of important parts.18Cr2Ni4WA屬于高強(qiáng)度中合金滲碳鋼。要使C化物及奧氏體含量不超標(biāo)可采用滲碳后高溫回火900~920℃滲碳,600~650回火,深冷處理,油淬后的硬度也就是48左右,想要達(dá)到HRC58-63,必須要進(jìn)行表面滲碳。
