鋼球開裂原因分析：某公司送檢成品鋼球5粒（斷裂成半粒的鋼球），材料為GCr15軸承鋼，加工工藝過程如下：φ6.0mm熱軋盤圓（連鑄）→球化退火后冷拔成φ4.5mm→去應力退火后冷拔成φ3.2mm→去應力退火后冷拔成φ2.5mm→冷鐓成鋼球→冷、熱加工成φ2.36mm成品鋼球。該批次鋼球共300萬粒，用戶在使用過程中發(fā)現(xiàn)約60粒開裂成兩半，要求對鋼球發(fā)生開裂的原因進行分析，山東專業(yè)鋼球規(guī)格尺寸。 </p> <p> 觀察與分析 </p> <p> 宏觀形貌 </p> <p> 送檢的5個半粒鋼球斷口的中心部位材料均呈現(xiàn)為線狀分布，邊緣光亮且凹凸不平，具有明顯的擠壓、磨損痕跡。接下來進行斷口的微觀形貌觀察與分析： </p> <p> 為了更詳細地觀察缺點形貌，任取半粒鋼球放置在JSM-6380LV掃描電子顯微鏡下變倍觀察斷口形貌，結果表明：鋼球中心部位約五分之三斷口呈現(xiàn)為深淺不一平行的條帶狀，形貌自然、疏松，其余部位主要呈現(xiàn)為擠壓、磨損狀態(tài)，局部為瓷狀斷裂面，斷口的微觀形貌見圖2～圖5。采用EDS7582能譜儀對條帶處的多處部位進行微區(qū)成分分析，發(fā)現(xiàn)材料內存在異常元素，山東專業(yè)鋼球規(guī)格尺寸，主要為氧，山東專業(yè)鋼球規(guī)格尺寸、鈣、鎂及微量的鈉。一些特殊材質鋼球已被廣泛應用于國民經濟各個領域中。山東專業(yè)鋼球規(guī)格尺寸</p><div

化學成分不銹鋼的耐蝕性隨含碳量的增加而降低，因此，大多數(shù)不銹鋼的含碳量均較低，***大不超過1.2%，有些鋼的Wc（含碳量）甚至低于0.03%（如00Cr12）。不銹鋼中的主要合金元素是Cr（鉻），只有當Cr含量達到一定值時，鋼才有耐蝕性。因此，不銹鋼一般Cr（鉻）含量至少為10.5%。不銹鋼中還含有Ni、Ti、Mn、N、Nb、Mo、Si、Cu等元素用途不銹鋼不易產生腐蝕、點蝕、銹蝕或磨損。不銹鋼還是建筑用金屬材料中強度***高的材料之一。 </p> <p> 由于不銹鋼具有良好的耐腐蝕性，所以它能使結構部件長久地保持工程設計的完整性。含鉻不銹鋼還集機械強度和高延伸性于一身，易于部件的加工制造，可滿足建筑師和結構設計人員的需要。 </p><p> 碳鋼球，又叫做碳鋼珠，主要是用Q235原材料生產加工，也就是低碳鋼球，根據(jù)是否熱處理分為兩種：一種是熱處理的，即加火，表層硬度達到HRC55-65；另一種是不熱處理的，也就是俗稱鐵球。在鋼球中是便宜的，使用范圍也廣，用量比較大。這得益于原材料的性能---碳鋼。 </p> <p> <br /> </p> <p> 那么什么是碳鋼呢？碳鋼，也就是碳素鋼，是指含碳量小于1.35%，除鐵、碳和限量以內的硅、錳、磷、硫等雜質外，不含其它合金元素的鋼。碳素鋼的性能主要取決于含碳量。含碳量增加，鋼的強度、硬度升高，塑性、韌性和可焊性降低。與其它鋼類相比，碳素鋼使用早，成本低，性能范圍寬，用量大。 </p> <p> 碳鋼根據(jù)含碳量分為低碳鋼（含C量0.04-0.25%），中碳鋼（含C量0.25-0.6%）,高碳鋼（含C量0.6-1.35%）。我們在碳鋼球生產中主要是用的低碳鋼球，不熱處理的情況下，容易焊接。多用于五金配件，鐵藝等要求比較低的。國際市場所用鋼球總量大約1800-2000萬噸。</p><div style="width:100%;text-align: center;"><img

Steel）指耐空氣、蒸汽、水等弱腐蝕介質和酸、堿、鹽等化學浸蝕性介質腐蝕的鋼，又稱不銹耐酸鋼。 </p> <p> 實際應用中，常將耐弱腐蝕介質腐蝕的鋼稱為不銹鋼，而將耐化學介質腐蝕的鋼稱為耐酸鋼。由于兩者在化學成分上的差異，前者不一定耐化學介質腐蝕，而后者則一般均具有不銹性。不銹鋼的耐蝕性取決于鋼中所含的合金元素。 </p> <p> 不銹鋼基本合金元素還有鎳、鉬、鈦、鈮、銅、氮等，以滿足各種用途對不銹鋼組織和性能的要求。不銹鋼容易被氯離子腐蝕，因為鉻、鎳、氯是同位原素，同位原素會進行互換同化從而形成不銹鋼的腐蝕。鋼球生產方式一般有鍛造、軋制、半固態(tài)成型及鑄造四大類。山東直銷鋼球值得信賴</p><p
