40Mn2 kub-rolled steel phaj yog ib hom nruab nrab- carbon alloy structural steel nrog zoo heev cov khoom, uas yog dav siv nyob rau hauv ntau yam industrial teb vim nws zoo zog, toughness thiab processability. Ntawm no yog cov lus qhia ntxaws ntxaws los ntawm cov yam ntxwv ntawm cov khoom siv, daim ntawv thov kev lag luam, kev siv thev naus laus zis thiab kev tswj kom zoo:

1. Cov yam ntxwv ntawm cov khoom tseem ceeb

Tshuaj muaj pes tsawg leeg

Cov tshuaj muaj pes tsawg leeg ntawm 40Mn2 yog tswj nruj heev, uas feem ntau suav nrog: carbon (C) cov ntsiab lus ntawm 0.37% -0.44%, uas yog lub hauv paus rau kev ua kom lub zog ntawm cov hlau; manganese (Mn) cov ntsiab lus ntawm 1.40% -1.80%, uas tuaj yeem txhim kho qhov hardenability thiab lub zog ntawm cov hlau, thiab tseem ua lub luag haujlwm hauv kev ua kom muaj zog ntxiv; Tsis tas li ntawd, cov ntsiab lus ntawm phosphorus (P) thiab sulfur (S) yog ob qho tib si tsawg dua los yog sib npaug rau 0.035%, uas ua rau muaj kev pheej hmoo ntawm brittleness thiab ua kom cov purity ntawm cov khoom.

Mechanical Properties

Tom qab kev kho cua sov kom zoo (xws li quenching thiab tempering), 40Mn2 kub- dov steel phaj muaj cov khoom siv zoo heev: lub zog tensile tuaj yeem ncav cuag 885MPa lossis ntau dua, lub zog tawm los yog ntau dua lossis sib npaug ntawm 735MPa, qhov elongation yog ntau dua lossis sib npaug li 10%, thiab qhov cuam tshuam rau lub zog loj dua 7 (Akv). Txawm tias nyob rau hauv lub kub - dov lub xeev, nws muaj lub zog zoo thiab toughness, uas muaj peev xwm ua tau raws li qhov yuav tsum tau siv ntawm ntau yam qauv.

Kev ua tau zoo

Kub ua hauj lwm Performance: Nws muaj cov yas zoo kub, thiab yog tsim rau kub dov, forging thiab lwm yam kub ua hauj lwm txheej txheem. Thaum lub sij hawm ua hauj lwm kub, qhov kub ntawm qhov tsim nyog (feem ntau 1100-850 degree) yuav tsum tau tswj xyuas kom muaj kev sib sau zoo.

Machineability: Hauv lub xeev annealed, lub machinability yog qhov zoo, uas tuaj yeem ua tiav los ntawm kev tig, milling, drilling thiab lwm txoj hauv kev kom tau txais qhov tseeb dua qhov tseeb thiab qhov chaw tiav.

Hardenability: Nws muaj hardenability zoo dua li cov pa roj carbon zoo tib yam. Rau workpieces nrog ib seem thickness tsawg dua 50 hli, uniform hardening tuaj yeem ua tiav los ntawm cov dej txias, uas yog qhov tsim nyog kom tau txais cov khoom zoo li qub.

 

 

 

 

 

 

2. Daim ntawv thov teb

Vim nws qhov kev ua tau zoo heev, 40Mn2 kub- dov steel phaj yog dav siv hauv cov teb hauv qab no:

 

Mechanical Manufacturing: Nws yog siv los tsim ntau yam shafts, zog, bolts, txiv ntseej thiab lwm yam khoom siv kho tshuab uas dais nruab nrab loads thiab cuam tshuam, xws li kis tau tus mob hauv tsheb thiab tsheb laij teb, iav blanks, thiab lwm yam.

Engineering Machinery: Nws tuaj yeem siv los ua cov txheej txheem ntawm engineering machinery xws li excavators thiab loaders, uas yuav tsum tau tiv thaiv tej yam loads thiab hnav.

Hydraulic thiab Pneumatic Systems: Nws yog siv los tsim lub tog raj kheej hydraulic, piston rods thiab lwm yam khoom uas yuav tsum tau muaj zog thiab hnav tsis kam.

Aerospace thiab Railway: Hauv qee cov khoom siv hauv aerospace thiab cov tsheb ciav hlau, 40Mn2 kub- dov steel phaj kuj tau siv vim lawv cov kev ua tau zoo.
