18cr2ni4Wa Alloy Steel phaj hais txog ib hom hlau phaj tsim los ntawm cov khoom siv hlau ua tiav ntawm cov khoom lag luam hlau xyoo thiab yog siv dav dav hauv ntau-}}}}}}} kawg tsim teb. Cov hauv qab no yog cov lus qhia ntxaws ntxaws:

Tshuaj Muaj Tshuaj

Carbon (c): 0.13-0.19%, uas cov cwj pwm uas muaj zog thiab cov plastonity thiab zam kom tsis txhob muaj cov roj carbon brittleness.

Silicon (si): 0.17-0.37%, uas pab kom ua kom zoo dazidation thiab kub ua haujlwm.

Manganese (mn): 0.30-0.60%, uas tseem yuav ua rau muaj kev ua haujlwm zoo rau deoxidation thiab kub ua haujlwm.

Sulphur (s): Tsawg dua lossis sib luag rau 0.025%, thiab txwv cov ntsiab lus ntawm leej faj tuaj yeem ua kom cov khoom siv thiab nws txoj kev tiv thaiv rau hydrogen brittlement.

Phosphorus (p): Tsawg dua lossis sib luag rau 0.025%, zoo ib yam li leej faj, tswj cov ntsiab lus phosphorus kuj yog ua kom muaj qhov zoo ntawm cov khoom siv.

Chromium (cr): 1.35-1.65%, uas tuaj yeem txhim kho lub hardenability, kev nruj thiab corrosion tsis kam ntawm cov hlau.

Npib tsib caug (ni): 4.00 {{- 4.50, uas tuaj yeem txhim kho qhov tsawg-qhov kub thiab ua haujlwm ua ke nrog cov tawv nqaij ua ke thiab xeb tsis kam ntawm cov hlau.

Tooj Liab (Cu): Tsawg dua lossis sib luag rau 0.025%, tswj cov ntsiab lus tooj liab tuaj yeem zam qee cov teebmeem tsis zoo ntawm cov khoom siv khoom.

Tungsten (w): 0.80 {{{-} 1.20%, uas tuaj yeem kho cov nplej thiab txhim kho qhov kev kub siab-tshuab hluav taws xob siab ntawm cov hlau.

 

 

 

 

 

 

Cov Khoom Siv Neeg Kho Tshuab

Siab Zog: Lub tensile lub zog yog ntau dua los yog sib npaug rau 1180 MPa, thiab cov txiaj ntsig zoo tshaj lossis sib npaug ntau dua 1029 MPA), uas tuaj yeem tiv thaiv hnyav thiab cuam tshuam2.

Zoo plasticity thiab toughtness: Lub elongation loj dua los yog sib npaug ntawm 108%, qhov cuam tshuam loj dua los yog sib npaug ntawm 45%, qhov kev cuam tshuam nrog 45%

Kev nyuaj gradient: Hauv lub xeev tus me nyuam, lub hardness yog tsawg dua lossis sib npaug nrog 269 HB, uas yooj yim rau kev txiav thiab ua. Tom qab carburizing, lub hardness nto tuaj yeem ncav cuag hrc58-63, thiab cov tseem ceeb ntawm lub plhaub "qauv mos thiab kev pabcuam lub neej ntawm cov khoom siv2.
