冷軋精密光亮鋼管的冷脆性(或低溫脆化傾向)用韌性一脆性轉(zhuǎn)化溫度Tc表示。高純鐵(0.01%C)的Tc在一100C，低于此溫度則完全處于脆化狀態(tài)。冷軋精密光亮鋼管中大多數(shù)合金元素都升高冷軋精密光亮鋼管的韌性一脆性轉(zhuǎn)化溫度，增加冷脆傾向。在室溫以上韌性斷裂時，冷軋精密光亮鋼管的斷口為韌窩型斷口，而在低溫下脆性斷裂時為解理斷口。冷軋精密光亮鋼管的低溫脆化的原因是：(1)形變時位錯源產(chǎn)生的位錯被障礙物(如晶界、第二相等)阻塞時，局部應力超過冷軋精密光亮鋼管的理論強度而產(chǎn)生微裂紋。(2)幾個塞積的位錯在晶界合成一個微裂紋。(3)兩個{110)滑移帶相交處反應，引起不動位錯%26lt;010%26gt;，呈楔形微裂紋，它可沿{100}解理面裂開(見圖1b)。 </p> <p> 增加冷軋精密光亮鋼管冷脆的因素有：(1)固溶強化元素。磷升高韌性一脆性轉(zhuǎn)化溫度強烈；還有鉬、鈦和釩；含量低時影響不大而含量高時升高韌性一脆性轉(zhuǎn)化溫度的元素有，硅、鉻和銅；降低韌性一脆性轉(zhuǎn)化溫度的有鎳，先降低后升高韌性一脆性轉(zhuǎn)化溫度的有錳。(2)形成第二相的元素。以第二相增加冷軋精密光亮鋼管冷脆重要的元素為碳，隨冷軋精密光亮鋼管中碳含量增加，冷軋精密光亮鋼管中珠光體含量增加，平均每增加1%珠光體體積，韌性一脆性轉(zhuǎn)化溫度平均升高2．2℃。圖2為鐵素體一珠光體鋼中碳含量對脆性的影響。加入鈦、鈮和釩等微合金化元素，形成彌散分布的氮化物或碳氮化物，引起冷軋精密光亮鋼管的韌性一脆性轉(zhuǎn)化溫度上升。(3)晶粒尺寸影響韌性一脆性轉(zhuǎn)化溫度，隨晶粒粗化，韌性一脆性轉(zhuǎn)化溫度升高。細化晶粒則降低冷軋精密光亮鋼管的冷脆傾向，這是廣為應用的方法。

/> 化學成分：碳（C）量是0.42~0.50%，Si含量為0.17~0.37%，Mn含量0.50~0.80%，Cr含量<=0.25%。<br /> 45#精密無縫鋼管熱處理方法：<br /> 熱處理溫度：正火850，淬火840，回火600. <br /> 45#精密無縫鋼管為優(yōu)質(zhì)碳素結(jié)構(gòu)用鋼 ,硬度不高易切削加工,模具中常用來做模板,梢子,導柱等,但須熱處理。 <br /> 1. 45#精密無縫鋼管淬火后沒有回火之前，硬度大于HRC55（可達HRC62）為合格。 <br /> 實際應用的硬度為HRC55（高頻淬火HRC58）。 <br /> 2. 45#精密無縫鋼管不要采用滲碳淬火的熱處理工藝。 <br /> 調(diào)質(zhì)處理后零件具有良好的綜合機械性能，廣泛應用于各種重要的結(jié)構(gòu)零件，特別是那些在交變負荷下工作的連桿、螺栓、齒輪及軸類等。但表面硬度較低，不耐磨?？捎谜{(diào)質(zhì)+表面淬火提高零件表面硬度。 <br /> 滲碳處理一般用于表面耐磨、芯部耐沖擊的重載零件，其耐磨性比調(diào)質(zhì)+表面淬火高。其表面含碳量0.8－－1.2%，芯部一般在0.1－－0.25%（特殊情況下采用0.35%）。經(jīng)熱處理后，表面可以獲得很高的硬度（HRC58－－62），芯部硬度低，耐沖擊。 </p> <p> 公司生產(chǎn)產(chǎn)品主要包括：軸承用冷軋精密鋼管、鋼筋連接套筒用冷軋精密鋼管、非標中空絲桿用冷軋精密鋼管、機械加工用冷軋精密無縫鋼管、汽車減震器用冷軋精密鋼管、摩托車減震器用冷軋精密鋼管、電機外殼專用精密鋼管、液壓和氣動缸筒用精密內(nèi)徑無縫鋼管等。 <br /> 其顯著特點是：1、冷軋精密鋼管公差尺寸精度高，產(chǎn)品精度控制±0.05mm；光潔度好；內(nèi)外表面無氧化層，內(nèi)壁清潔度好。2、冷軋精密鋼管的綜合性能優(yōu)良，能承受高壓，冷彎、擴口、壓扁不開裂，不皺皮，能作各種復雜變形及機械加工處理。3、精密無縫管的推廣應用可以節(jié)約鋼材，提高加工工效，減少加工工序和設備投資，可以節(jié)約費用和大大節(jié)約機械加工工時，提高生產(chǎn)量和材料利用率，同時有利于提高產(chǎn)品質(zhì)量，降低成本。
