摘要：<div>SUS321不銹鋼化學成分及熱處理<br /> SUS321不銹鋼是Ni-Cr-Mo型奧氏體不銹鋼，在304的基礎(chǔ)上加入了金屬鈦，使其具有了更好的耐晶界腐蝕性及高溫強度。由于添加金屬鈦，使其有效地控制了碳化鉻的形成。</div> <div>SUS321不銹鋼具有優(yōu)異的高溫應(yīng)力破斷(Stress&nbsp;Rupture)性能及高溫抗?jié)撟冃?Creep&nbsp;Resistance)應(yīng)力機械性能都非常好。</div> <div>SUS321不銹鋼力學性能牌號抗拉強度&sigma;b&nbsp;(MPa)&nbsp;屈服強度&sigma;0.2&nbsp;(MPa)&nbsp;伸長率&delta;5&nbsp;(％)&nbsp;</div> <div>斷面收縮率&psi;&nbsp;(％)&nbsp;硬度HV&nbsp;SUS321&nbsp;&ge;520&ge;205&ge;40&ge;50&le;200</div> <div>SUS321不銹鋼熱處理規(guī)范：</div> <div>1)固溶920～1150℃快冷;&nbsp;</div> <div>&nbsp;2)根據(jù)需方要求可進行穩(wěn)定化處理熱處理溫度為850～930℃但必須在合同中注明。</div> <div>SUS321交貨狀態(tài)</div> <div>一般以熱處理狀態(tài)交貨，其熱處理種類在合同中注明；未注明者，按不熱處理狀態(tài)交貨。</div> <div>SUS321不銹鋼化學成分&nbsp;</div> <table border="1" cellspacing="0" cellpadding="0"> <tbody> <tr> <td valign="top" width="63"> <div>牌號</div> </td> <td valign="top" width="62"> <div>C</div> </td> <td valign="top" width="50"> <div>Si</div> </td> <td valign="top" width="60"> <div>Mn</div> </td> <td valign="top" width="76"> <div>P</div> </td> <td valign="top" width="63"> <div>S</div> </td> <td valign="top" width="68"> <div>Cr</div> </td> <td valign="top" width="63"> <div>Ni</div> </td> <td valign="top" width="63"> <div>Ti</div> </td> </tr> <tr> <td valign="top" width="63"> <div>SUS321</div> </td> <td valign="top" width="62"> <div>0.08</div> </td> <td valign="top" width="50"> <div>1</div> </td> <td valign="top" width="60"> <div>2</div> </td> <td valign="top" width="76"> <div>&le;0.045</div> </td> <td valign="top" width="63"> <div>&le;0.032</div> </td> <td valign="top" width="68"> <div>17.0-19.0</div> </td> <td valign="top" width="63"> <div>5C-0.7</div> </td> <td valign="top" width="63"> <div>9.0-12.0</div> </td> </tr> </tbody> </table> <div>SUS321不銹鋼力學性能</div> <table border="1" cellspacing="0" cellpadding="0"> <tbody> <tr> <td valign="top" width="95"> <div>牌號</div> </td> <td valign="top" width="95"> <div>抗拉強度</div> <div>&sigma;b&nbsp;(MPa)&nbsp;</div> </td> <td valign="top" width="95"> <div>屈服強度</div> <div>&sigma;0.2&nbsp;(MPa)</div> </td> <td valign="top" width="95"> <div>伸長率</div> <div>&delta;5&nbsp;(％)</div> </td> <td valign="top" width="95"> <div>斷面收縮率</div> <div>&psi;(％)&nbsp;</div> </td> <td valign="top" width="95"> <div>硬度</div> <div>HV）</div> </td> </tr> <tr> <td valign="top" width="95"> <div>SUS321</div> </td> <td valign="top" width="95"> <div>&ge;520</div> </td> <td valign="top" width="95"> <div>&ge;205</div> </td> <td valign="top" width="95"> <div>&ge;40</div> </td> <td valign="top" width="95"> <div>&ge;50</div> </td> <td valign="top" width="95"> <div>&le;200</div> </td> </tr> </tbody> </table> <div> <div>SUS32不銹鋼應(yīng)用</div> <div>SUS321不銹鋼在不同濃度、不同溫度的有機酸和無機酸中，尤其是在氧化性介質(zhì)中具有良好的耐磨蝕性能，</div> <div>用于制造耐磨酸容器和耐磨設(shè)備的襯里、輸送管道。</div> <div>應(yīng)用于抗晶界腐蝕性要求高的化學、煤炭、石油產(chǎn)業(yè)的野外露天機器，建材耐熱零件及熱處理有困難的零件。<br /> <div>公司至成立以來，以&ldquo;誠信、合作、雙贏、發(fā)展&rdquo;為經(jīng)營宗旨，堅持&ldquo;價格**、用戶、信譽&rdquo;的營銷理念，在市場上獲得了良好的口碑。<br /> &nbsp;&nbsp; 029&mdash;88633755<br /> 詳情參考：<a href="http://www.258prod.com/">http://www.258prod.com</a></div> </div> </div>
