class="khcont">16MN合金管是：16Mn叫低合金高強(qiáng)度結(jié)構(gòu)鋼低合金高強(qiáng)度結(jié)構(gòu)鋼：含碳量為0.1%-0.25%,加入主要合金元素錳、硅、釩、鈮和鈦等；它的含合金總量<3%。按強(qiáng)度分為300、350、400和450MPa等4個(gè)級別。主要有Q295、Q345、Q390、Q420、Q460。：“Q”是屈服的“屈”字的漢語拼音大寫字頭，其后數(shù)字為該牌號小屈服點(diǎn)（σs）值，其后的符號是按照該鋼雜質(zhì)元素（硫、磷）含量由高到低并伴隨碳、錳元素的變化而分為A、B、C、D四等。其中A、B級鋼通常稱16Mn 高壓合金鋼管合金管與無縫管兩者既有關(guān)系又有區(qū)別，不能混為一談。合金管是鋼管按照生產(chǎn)用料（也就是材質(zhì)）來定義的，顧名思義就是合金做的管子；而無縫管是鋼管按照生產(chǎn)工藝（有縫無縫）來定義的，區(qū)別于無縫管的就是有縫管，包括直縫焊管和螺旋管。</div><p><img

class="para"> 高壓鍋爐管是鍋爐管的一種，屬于無縫鋼管類別。制造方法與無縫管高壓鍋爐管相同，但對制造鋼管所用的鋼種有嚴(yán)格的要求。高壓鍋爐管使用時(shí)經(jīng)常處于高溫和高壓條件。高壓鍋爐管主要用來制造高壓和超高壓鍋爐的過熱器管、再熱器管、導(dǎo)氣管、主蒸汽管等。 </div> <div id="dcjnio9" class="para"> 鍋爐管由于長期在高溫和高壓條件下工作，材料將發(fā)生蠕變，塑性和韌性下降，原始組織改變，產(chǎn)生腐蝕等。作為鍋爐用的鋼管應(yīng)具備：（1）足夠的持久強(qiáng)度；（2）足夠的塑性變形能力；（3）小的時(shí)效傾向和熱脆性；（4）高的抗氧化、耐煤灰、耐天然氣高溫下腐蝕、蒸汽和應(yīng)力腐蝕性能；（5）良好的組織穩(wěn)定性以及良好的工藝性能。高壓鍋爐管的鋼種有碳鋼以及珠光體、鐵素體和奧氏體型不銹耐熱鋼。為了提高火力發(fā)電機(jī)組的熱效率、降低燃耗，世界各國均以發(fā)展大容量、高參數(shù)（高溫、高壓）火電機(jī)組（1000MW以上）為主。蒸汽壓力提高到31.5～34.3MPa，過熱蒸汽溫度達(dá)595～650℃，向超高壓臨界壓力發(fā)展，這樣對高壓鍋爐管提出了更高的要求。為此開發(fā)了新的鋼種，以滿足高參數(shù)電站鍋爐的需用。

1、組織強(qiáng)化需要母相，即在鋼管的元素中要含有發(fā)生組織強(qiáng)化的母相。 </div> <div id="p8w9ejz" class="para"> 2、組織強(qiáng)化是一個(gè)過程，包括組織形變及組織擴(kuò)散，隨著冷卻環(huán)境的改變，合金鋼管組織結(jié)構(gòu)可能有兩種變化方式，即有擴(kuò)散和無擴(kuò)散，在低溫環(huán)境里，無擴(kuò)散決定著組織形變的過程；在高溫環(huán)境中，擴(kuò)散決定著組織結(jié)構(gòu)的改變。 </div> <div id="crthcmm" class="para"> 3、組織強(qiáng)化有兩個(gè)重要因素，即組織應(yīng)變和環(huán)境冷卻。例如在加熱環(huán)境或者冷卻環(huán)境中，合金鋼管的組織會隨著溫度的改變而逐漸改變，能量狀態(tài)由低轉(zhuǎn)變?yōu)楦?。另外，查看鋼管現(xiàn)貨可以知道，在合金鋼管中，少量介質(zhì)含有極其精細(xì)的密度。因此，在調(diào)整鋼管的結(jié)構(gòu)性能時(shí)，要時(shí)刻注意合金鋼管的組織性能。
