27MnCrB5-2 Alloy Steel Phaj

Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm cov kws tshaj lij 27mncrb5-2 alloy steel phaj tuam ntxhab thiab cov muag khoom hauv Suav teb. Txais tos rau kev lag luam wholesale customized 27mncrb5-2 alloy steel phaj ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.

27MnCrB5-2 alloy steel phaj

27MnCrB5-2 yog cov khoom siv hlau alloy uas feem ntau ntxiv manganese, chromium, boron thiab lwm yam khoom los txhim kho lub zog thiab tawv ntawm cov khoom. Cov ntsiab lus yog raws li nram no:

Cov yam ntxwv: 27MnCrB5-2 alloy steel phaj muaj lub zog zoo thiab tawv, thiab tuaj yeem ua tiav lub zog siab thiab zoo plasticity tom qab kev kho cua sov. Nyob rau tib lub sijhawm, ntxiv cov khoom boron tuaj yeem txhim kho hardness ntawm cov khoom thiab muaj kev hnav zoo dua.

Kev Siv: 27MnCrB5-2 alloy steel phaj yog siv los tsim cov khoom thiab cov khoom siv nrog cov kev xav tau siab rau lub zog siab, siab tawv thiab hnav tsis kam, xws li tsav ncej, lub log, cov khoom siv kho tshuab, thiab lwm yam.

Thermal processing specifications: 27MnCrB5-2 tuaj yeem raug ua raws li cov txheej txheem thermal, tab sis yuav tsum tau them nyiaj rau kev tswj cov cua sov, lub sijhawm thiab txoj kev txias kom tsis txhob muaj teeb meem xws li tawg thiab deformation ntawm cov khoom.

Mos annealing specification: 27MnCrB5-2 tuaj yeem softened thiab annealed los txhim kho nws cov kev ua tau zoo. Qhov kub thiab txias yog 680-720 degree, tuav lub sijhawm yog 1-2 teev, thiab tom qab ntawd maj mam txias lossis cua txias yog siv los ua kom tiav cov qauv zoo ib yam.

quenching thiab tempering specifications: Rau qhov chaw uas yuav tsum tau siab dua, quenching thiab tempering yuav ua tau los txhim kho lawv lub zog thiab toughness. Qhov kub quenching yog 820-870 degree, ua raws li cov roj txias sai; tempering kub yog 200-300 degree, tuav lub sij hawm yog 1-2 teev.

Cov ntawv thov: 27MnCrB5-2 yog dav siv los tsim cov khoom thiab cov khoom siv uas yuav tsum tau muaj zog, siab tawv thiab hnav tsis kam, xws li tsav ncej, lub log, cov khoom siv kho tshuab, thiab lwm yam.

Chemical Composition thiab Mechanical Property:

Txij li xyoo 2008, Gnee Group tau muab cov khoom siv hlau zoo rau ntau tshaj 600 tus neeg siv khoom hauv ntau dua 70 lub teb chaws thoob ntiaj teb. Peb tau tsim kev sib raug zoo ntev -kev sib raug zoo nrog ntau lub chaw tsim khoom hauv Suav teb los xyuas kom meej tias peb cov khoom raug tsim los ntawm cov khoom siv siab- cov ntaub ntawv zoo thiab ua ke nrog ntau yam qauv thoob ntiaj teb, nrog rau txhua xyoo export ntim ntau tshaj 80,000 tons. Gnee Group tau cog lus tias yuav dhau los ua cov pab pawg sib tw thoob ntiaj teb thoob ntiaj teb, ua tau raws li cov kev xav tau sib txawv ntawm cov neeg siv khoom sib txawv, thiab paub tseeb tias: ib qho - nres kev pabcuam, xaiv yooj yim dua.
