12cr1movg鍋爐管表示方法:
① 鋼號(hào)開頭的兩位數(shù)字表示鋼的碳含量,以平均碳含量的萬(wàn)分之幾表示,如40Cr。
?、阡撝兄饕辖鹪?,除個(gè)別微合金元素外,一般以百分之幾表示。當(dāng)平均合金含量<1.5%時(shí),鋼號(hào)中一般只標(biāo)出元素符號(hào),而不標(biāo)明含量,但在特殊情況下易致混淆者,在元素符號(hào)后亦可標(biāo)以數(shù)字"1",例如鋼號(hào)"12CrMoV"和"12Cr1MoV",前者鉻含量為0.4-0.6%,后者為0.9-1.2%,其余成分全部相同。當(dāng)合金元素平均含量≥1.5%、≥2.5%、≥3.5%……時(shí),在元素符號(hào)后面應(yīng)標(biāo)明含量,可相應(yīng)表示為2、3、4……等。例如18Cr2Ni4WA。
?、垆撝械拟CV、鈦Ti、鋁AL、硼B(yǎng)、稀土RE等合金元素,均屬微合金元素,雖然含量很低,仍應(yīng)在鋼號(hào)中標(biāo)出。例如20MnVB鋼中。釩為0.07-0.12%,硼為0.001-0.005%。
?、芨呒?jí)優(yōu)質(zhì)鋼應(yīng)在鋼號(hào)最后加"A",以區(qū)別于一般優(yōu)質(zhì)鋼。
?、輰iT用途的合金結(jié)構(gòu)鋼,鋼號(hào)冠以(或后綴)代表該鋼種用途的符號(hào)。例如鉚螺專用的30CrMnSi鋼,鋼號(hào)表示為ML30CrMnSi。
合金管與無(wú)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(lái)定義的,顧名思義就是合金做的管子;而無(wú)縫管是鋼管按照生產(chǎn)工藝(有縫無(wú)縫)來(lái)定義的,區(qū)別于無(wú)縫管的就是有縫管,包括直縫焊管和螺旋管。
