100Cr6(1.3505) 軸承鋼 100Cr6鍛件、棒材、管材簡介

高碳軸承鋼 - 組別及性能

軸承鋼或滾動體用鋼的特點(diǎn)是碳含量非常高 - 約 1%。它的特點(diǎn)是硬度高、化學(xué)成分純度高、硬化能力高、強(qiáng)度高、靜態(tài)疲勞,此外還具有足夠的材料耐久性。在這種類型的鋼中,主要強(qiáng)調(diào)的是耐磨性。組件(例如滾子、環(huán)、球體)和更接近應(yīng)用的其他組件會持續(xù)運(yùn)動,通常在高壓下與其他組件接觸。在許多情況下,需要特定鋼的特定耐腐蝕性和耐高溫性。在某些情況下,通過化學(xué)成分可以確定和評估工具鋼下的軸承鋼。軸承鋼必須具有高切削加工性、熱處理過程中不變形、非金屬夾雜物和硫、磷、氧以及有限的表面去污敏感性。

材料 100Cr6(1.3505) 鋼是 DIN 17230 規(guī)定的滾珠軸承應(yīng)用中常用的高碳高鉻鋼。100Cr6在調(diào)質(zhì)后具有良好的耐磨性、較高的硬度和熱處理(淬火和低溫回火)后的接觸疲勞性能??捎糜谥圃旄鞣N軸承套圈和滾動體,如內(nèi)燃機(jī)、電力機(jī)車、汽車、拖拉機(jī)、機(jī)床、軋鋼機(jī)、鉆床、礦山機(jī)械、通用機(jī)械以及高速旋轉(zhuǎn)的高速負(fù)載機(jī)械傳動軸承球和套圈。有時也用于制作沖模、量具等工具,或需要大載荷的場合。

軸承鋼的熱處理及交貨條件

軸承鋼以軟化狀態(tài)提供,具有棒材、板材、管材、鍛件或環(huán)形式的精細(xì)結(jié)構(gòu)的球狀滲碳體結(jié)構(gòu)。除了原材料之外,軸承鋼還以拉制、磨削和去皮棒材的形式存在。熱處理不是簡單的,所以在特殊條件下進(jìn)行,在820-840℃的溫度下進(jìn)行奧氏體化,然后在油中硬化,在180℃回火1-2小時。完成熱處理工藝后,產(chǎn)品具有板條馬氏體組織,硬度超過62 HRC。

用于生產(chǎn)軸承的其他鋼材

除軸承鋼組外,滾動軸承還經(jīng)常使用其他滲碳鋼,如 18CrNiMo7-6、21CrNiMo2-2、20Cr3、20CrMo4,表面硬化鋼 - 56Mn4、70Mn4,不銹鋼和耐腐蝕鋼,如X89CrMoV18、X65Cr14和高速鋼80MoCrV42-16、X82WMoCrV6-5-2、X75WCrV18-4-1。

化學(xué)成分和合金添加劑

對于過共析鋼,使用添加劑,例如大約 1.35-2.05% 范圍內(nèi)的鉻 - 鉻、錳 - 錳和硅 - 硅,以提高材料的硬化能力。在這些應(yīng)用中,滲碳鋼更容易進(jìn)行冷成型并且具有良好的芯部延展性。不銹鋼可以在高溫下工作。

由軸承鋼制成的棒材、管材和板材

所述軸承鋼和滾動軸承用鋼由 PN-74/H-84041、BN-72/H-0641-06 和 PN-EN ISO 683-17 定義,公司根據(jù)這些標(biāo)準(zhǔn)提供:
