冷鐓鋼成型用鋼,冷鐓是在室溫下采用一次或多次沖擊加載,廣泛用于生產(chǎn)螺釘,銷釘,螺母等標(biāo)準(zhǔn)件.冷鐓工藝可節(jié)省原料,降成本,而且通過(guò)冷作硬化提高工作的抗拉強(qiáng)度,改善性能,冷鐓用鋼必須其有良好的冷頂鍛性能,鋼中S和P等雜質(zhì)含量減少,對(duì)鋼材的表面質(zhì)量要求嚴(yán)格,經(jīng)常采用優(yōu)質(zhì)碳鋼,若鋼的含碳鋼大于0.25%,應(yīng)進(jìn)行球化退火熱處理,以改善鋼的冷鐓性能. 冷鐓鋼盤條一般為低、中碳優(yōu)質(zhì)碳素結(jié)構(gòu)鋼和優(yōu)質(zhì)合金結(jié)構(gòu)鋼，用來(lái)冷鐓成型制造各種機(jī)械標(biāo)準(zhǔn)件和緊固件。因冷鐓工藝要求該鋼具有高的潔凈度，控制鋼中的Si、Al的含量，采用控制軋制和控制冷卻工藝，避免出現(xiàn)馬氏體、貝氏體和魏氏體組織，使鋼材具有細(xì)晶和碳化物球化組織，以提高鋼材的塑性和冷頂鍛性能。介紹了國(guó)內(nèi)外冷鐓鋼的開發(fā)和生產(chǎn)情況，化學(xué)成分對(duì)冷鐓性能的影響，冷鐓鋼的生產(chǎn)工藝特長(zhǎng)。   冷鐓鋼盤條的鋼種一般為低、中碳優(yōu)質(zhì)碳素結(jié)構(gòu)鋼和合金結(jié)構(gòu)鋼。冷鐓鋼產(chǎn)品主要用于汽車、造船、設(shè)備制造、電子、家電、自行車、工具、輕鋼結(jié)構(gòu)、建筑等行業(yè)。   冷鐓鋼因冷成型性能良好，在機(jī)械加工行業(yè)用冷拔代替熱軋材冷切削機(jī)加工，這種工藝的優(yōu)點(diǎn)是在節(jié)約大量工時(shí)的同時(shí)，金屬消耗可以降低10%~30%，而且產(chǎn)品尺寸精度高，表面光潔度好，生產(chǎn)率高，是近年來(lái)興起的較先進(jìn)的機(jī)加工工藝。 冷鐓鋼：ML04Al ML08Al ML10Al ML15Al ML15 ML20Al ML20 ML18Mn ML22Mn ML20Cr ML25 ML30 ML35 ML40 ML45 ML15Mn ML25Mn ML30Mn ML35Mn ML37Cr ML40Cr ML30CrMo ML35CrMo ML42CrMo ML20B ML28B ML35B ML15MnB ML20MnB ML35MnB ML37CrB ML20MnTiB ML15MnVB ML20MnVB U40048 U40088 U40108 U40158 U40152 U40208 U40202 U41188 U41228 A20204 U40252 U40302 U40352 U40402 U40452 L20158 U41252 U41302 U41352 A20374 A20404 A30304 A30354 A30424 A70204 A70284 A70354 A71154 A71204 A71354 A20378 A74204 A73154 A73204 德13MF4 18MF5 35FM6 45MF6.1 45MF6 C15E2C CQ15 C20E2C CQ22 C35EC CQ35 C45EC CQ45 15CrNi6 CrMoVMo2-2 21NiCrMo2 30CrNiMo8 34CrNiMo6 38Cr1 46Cr1 38Cr2 46Cr2 15Cr3 34Cr4 37Cr4 41Cr4 16MnCr5 25CrMo4 34CrMo4 42CrMo4 20MoCr4 1.1132 1.1152 1.1172 1.1192 1.5919 1.6523 1.6580 1.6582 1.7001 1.7002 1.7003 1.7006 1.7015 1.7033 1.7034 1.7035 1.7031 1.7218 1.7220 1.7225 1.7321 國(guó)CC4X CC4A CC8X CC8A CC11X CC11A CC15X CC15K CC15A CC21K CC21A CE10 CE15E4 CE16E4 CE20E4 20Cr4E 16MnCr5E 18CrMo4E 20NiCrMo2E CE20E4 CE28E4 CE35E4 CE40E4 CE45E4 42Mn6E 37Cr2E 46Mn6E 37Cr2E 46Mn6E 37Cr2E 46Cr2E 34Cr4E 37Cr4E 41Cr4E 36Mo3E 25Cr4Mo4E 34CrMo4E 42CrMo4E 41CrNiMo2E 41NiMo7E 31CrNiMo8E CE20BG1 CE20BG2 CE28B CE35B 35MnB5E 37CrB1E CE20E4 CE28E4 CE35E4 CE40E4 CE45E4 42Mn6E 37Cr2E 46Cr2E 34Cr4E 37Cr4 41Cr4E 36Mo3E 25CrMo4E 34CrMo4E 42CrMo4E 41CrMo2E 41NiCrMo7E 31CrNiMo8 EG1 31CrNiMo8 EG2 31CrNiMo8 CE20BG1 CE20BG2 CD28B CE35B 35MnB5E 37CrB1E 日SWRCH6R SWRCH8R SWRCH10R SWRCH12R SWRCH15R SWRCH17R SWRCH6A SWRCH8WA SWRCH10A SWRCH12A SWRCH15A SWRCH16A SWRCH18A SWRCH19A SWRCH20A SWRCH22A SWRCH25A SWRCH10K SWRCH12K SWRCH15K SWRCH16K SWRCH17K SWRCH18K SWRCH20K SWRCH22K SWRCH24K SWRCH25K SWRCH27K SWRCH30K SWRCH33K SWRCH35K SWRCH38K SWRCH40K SWRCH41K SWRCH43K SWRCH45K SWRCH48K SWRCH50K SWRCH6R SWRCH8R SWRCH10R C2C C4C C8C C10C C15C C17C C20C 8MnSi7 C10E2C C15E2C C17E2C C20E2C 10NiCr5-4 12CrMo4 12NiCr3-2 15B2 16MnCr5 16MnCrB5 16MnCrS5 17Cr3 17CrNi6-6 17CrS3 18B2 18CrMo4 18CrMoS4 18MnB4 20MnCrS5 20MnCr4 20MnCrS4 20NiCrMo2-2 20NiCrMoS6-4 22MnB4 C35EC C35RC C45EC C45RC 25CrMo4 25CrMoS4 34Cr4 34CrMo4 34CrNiMo6 37Cr4 37CrMo4 37Mo2 38Cr2 41Cr4 41CrS4 41NiCrMo7-3-2 42CrMo4 42CrMoS4 46Cr2 17B2 17MnB4 20MnB4 23B2 23MnB4 27MnB4 22B2 30MnB4 30MoB1 31CrMoB2-1 32CrB4 33B2 36CrB4 36MnB4 37MnB5 38B2 SWRCH6R SWRCH8R SWRCH10R SWRCH12R SWRCH15R SWRCH17R SWRCH6A SWRCH8A SWRCH10A SWRCH12A SWRCH15A SWRCH16A SWRCH18A SWRCH19A SWRCH19A SWRCH20A SWRCH22A SWRCH10K SWRCH12K SWRCH15K SWRCH16K SWRCH17K SWRCH20K SWRCH22K SWRCH24K SWRCH25K SWRCH27K SWRCH30K SWRCH33K SWRCH35K SWRCH38K SWRCH40K SWRCH41K SWRCH43K SWRCH45K SWRCH48K SWRCH50K SNB5-1 SNB7-2 SNB16-3 SNB21-1 SNB22-1 SNB23-1-5 SNB24-1-5
