  合金管15CrMo是无缝钢管的一种,其性能要比一般的无缝钢管高很多,因为这种钢管里面含Cr比较多,其耐高温、耐低温、耐合金管15CrMo腐蚀的性能是其他无缝钢管比不上的,所以合金管在石油、化工、电力、锅炉等行业的用途比较广泛。i  >30~50±0.3>3~20±10%力学性能:标准牌号抗拉强度(MPa)屈服强度(MPa)伸长率(%)硬度GB308710335~475≥195≥24/20410~550≥245≥20/GB531020G410~550≥245≥24/20MnG≥415≥240≥22/25MnG≥485≥275≥20/15CrMoG440~640≥235≥21/12Cr2MoG450~600≥280≥20/12Cr1MoVG470~640≥255≥21/12Cr2MoWVTiB540~735≥345≥18/10Cr9Mo1VNb≥585≥415≥20/ASME SA210SA210A-1≥415≥255≥30≤143HBSA210C≥485≥275≥30≤179HBASME SA213SA213 T11≥415≥205≥30≤163HBSA213 T12≥415≥220≥30≤163HBSA213 T22≥415≥205≥30≤163HBSA213 T23≥510≥400≥20≤220HBSA213 T91≥585≥415≥20≤250HBSA213 T92≥620≥440≥20≤250HBDIN17175ST45.8/Ⅲ410~530≥255≥21/15Mo3450~600≥270≥22/13CrMo44440~590≥290≥22/10CrMo910480~630≥280≥20/化学成分:标准牌号化学成分(%)M  /MPa 断裂时间W高品质  GB3093-1986(柴油机用高压无缝钢管)。主要用于柴油机喷射系统高压油管。其钢管一般为冷拔管,专业销售20g高压锅炉管,15crmog高压合金管,高压无缝管,12cr1movg高压锅炉管等各类产品种类齐全,畅销海内外,的设备,使用寿命长!产品电线产品行业领跑,欢迎来电咨询.其代表材质为20A。jV  8规格合金规格表单位:Kg/m      壁厚 外径33.544.555.56322.1462.4602.7623.0523.3293.5943.847382.5892.9783.3543.7184.0694.4084.735422.8853.3233.7494.1624.5624.9515.327453.1073.5824.0444.4954.9325.3585.771503.4774.0144.5385.0495.5496.0366.511543.7734.3594.9325.4936.0426.5787.103573.9954.6185.2285.8266.4126.9857.546604.2174.8775.5246.1596.7827.3927.99063.54.4765.1795.8696.5487.2147.8678.508684.8095.5676.3137.0477.7688.4779.174704.9575.7406.5117.2698.0158.7499.470735.1795.9996.8077.6028.3859.1569.914765.4016.2587.1037.9358.7559.56310.358896.3637.3808.3859.37810.35811.32612.2811087.7689.02010.25911.48612.70113.90315.09313311.17812.72514.26115.78317.29418.79215913.42215.29017.14618.98920.82122.63921918.60121.20923.80526.38828.95931.51727323.26226.53629.79733.04636.28339.50832527.75031.66535.56839.45843.33747.20235538.89743.15847.40651.641  37741.33945.87150.39054.897  42646.77751.91357.03662.147  450      480      530      630      单位:Kg/m      壁厚 外径6.5788.591012324.088     385.049     425.691     456.172     506.9737.4238.2868.699  547.6148.1149.0759.538  578.0958.6329.66710.167  608.5769.14910.25910.796  63.59.1379.75410.95011.529  689.85810.53011.83812.473  7010.17910.87612.23212.89213.53914.79717.1647310.66011.39412.82413.52114.20515.53718.0527611.14111.91213.41614.15014.87116.27718.9408913.22514.15615.98116.87517.75619.48322.78710816.27017.43619.72920.85821.97324.16828.41013320.27821.75124.66226.09827.52230.33435.80915924.44626.24029.79131.54833.29336.74643.50321934.06436.59841.62944.12646.61051.54361.25927342.72045.92052.28355.44558.59664.86077.24032551.05654.89762.54266.34670.13777.68492.62935555.86560.07668.46072.63476.79685.082101.50737759.39163.87372.80177.24681.67990.508108.01842667.24672.33282.46887.51892.555102.592122.51945071.09376.47587.20392.54997.882108.511129.62148075.90281.65493.12298.837104.540115.909138.49953083.91790.286102.987109.319115.638128.240153.29663099.947107.549122.716130.281137.833152.90218216Mn规格表规格数量规格数量规格数量规格数量规格数量规格数量406*1612457*3220508*8020530*2210660*8020820*5556406*1714457*3525508*9020530*2520660*9020820*6052406*1814457*4020508*10020530*2815660*10020820*7054406*1914457*4525530*1630610*3020660*15020820*8050406*2014457*5015530*1720610*3210710*2030820*9065406*2214457*5520530*1820610*3510710*2215820*10062406*2518457*6020530*1920610*4010710*2520820*15061406*2820457*6515530*2030610*4510710*2815820*20063406*3025457*7020530*2220610*5020710*3020864*4075406*3225457*8020530*2530610*5515710*3215864*5578406*3525457*9025530*2830610*6015710*3515864*6079406*4025457*10020530*3020610*6510710*4020864*7081406*4550480*1650530*3230610*7060710*4520864*8089406*5028480*1715530*3520610*8010710*5020864*9085406*5525480*1815530*4020610*9010710*5515864*10025406*6020480*1930530*4520610*10015710*6025864*15036406*6525480*2020530*5020610*15015710*6530864*20023406*7020480*2220530*5525630*1815710*7060900*6068406*8025480*2520530*6025630*1915710*8030900*7023406*9020480*2820530*6560630*2010710*9030900*8035426*1625480*3025530*7030630*2225710*10054900*9039426*1725480*3215530*8060630*2515710*15050900*10069426*1820480*3515530*9030630*2815720*2565900*150809合金钢管用途合金钢管主要用途是用于电厂,核电,高压锅炉,高温过热器和再热器等高压高温的管道上及设备上,它是采用优质碳素钢,合金结构钢和不锈耐热钢做材质,经热轧(挤、扩)或冷轧(拔)而成。  4.1 预热温度的选择
