M35 high-speed steel vim nws cov kev ua tau zoo heev, yog li kev lag luam raug hwm raws li qhov kev xaiv zoo tshaj plaws rau cov cuab yeej steel, hnub no peb yuav hais txog qee qhov kev kub ceev steel hauv tsev, M35 high-speed steel hauv kev tsim cov cuab yeej, seb qhov kev ua tau zoo txaus.
Cov txiaj ntsig ntawm cov khoom siv oxitriding, tag nrho hauv av Tin-coated khoom, tig cov cuab yeej, iav hobs, iav shaper riam thiab ntsia hlau flameters ua los ntawm M35 HSS yog txaus siab piv nrog cov cuab yeej HSS zoo xws li M2, M2AL, W9, W18 thiab M42. . Lub neej kev pab cuam, liab hardness thiab hnav tsis kam ntawm M35 high-ceev steel cov cuab yeej yog siab dua li ntawm domestic kev kub ceev steel, thaum lub thermal hardness, hnav tsis kam thiab compressive zog kuj siab dua M2AL, toughness thiab grindability yog me ntsis siab dua. tshaj M42 high-speed steel, yog li nws yuav tsum tau ua kom muaj zog txhawb kev ua haujlwm siab ceev hlau.
Hardness yog qhov feem ntau intuitive technical Performance index rau kev ntsuam xyuas cov cuab yeej high-speed steel, tab sis qhov tseem ceeb tshaj plaws ntawm kev kho cua sov zoo yog cov qauv metallographic. Txawm hais tias tam sim no, hardness yog ib qho kev ntsuas ntau dua los ntsuas qhov zoo ntawm kev kho cua sov, tab sis hardness yog qhov tshwm sim saum npoo, cov qauv metallographic yog qhov tseem ceeb. Vim hais tias tag nrho cov super-hard high-speed steel kom ncav cuag ntau tshaj 66HRC, nws tsuas yog ib txoj haujlwm yooj yim xwb, tab sis kom ua tiav lub koom haum metallographic zoo tagnrho, muaj qhov nyuaj heev. Tsis tas li ntawd, tag nrho cov super-hard high-speed steel, tsis txhob super-hardness. High-speed steel cov cuab yeej tsis txhais hais tias qhov siab dua qhov hardness, qhov zoo dua. Muaj peev xwm ua tau siab hardness thiab siv siab hardness yog ob qho teeb meem sib txawv kiag li. Rau M35 high-speed steel, 69HRC tuaj yeem ncav cuag los ntawm kev kho cua sov kom raug, tab sis cov cuab yeej 69HRC tsis muaj txiaj ntsig. Rau M35 high-speed steel cov cuab yeej, raws li kev paub dhau los ntawm kev ua haujlwm thiab cov ntaub ntawv hauv tsev thiab txawv teb chaws, nws yog qhov zoo tshaj plaws los tswj qhov hardness ntawm 66-67.5HRC yog qhov tseeb dua.
