AISI 4135 Alloy hlau

AISI 4135 yog Asmeskas tus qauv chromium-molybdenum alloy hlau uas ua raws li ASTM A29 / A29M-04 tus qauv. Cov khoom no nthuav tawm cov khoom zoo heev nrog lub zog zoo, hardness, thiab quenchability, nrog rau qhov kub thiab txias cuam tshuam toughness thiab high-temperature creep zog thiab durability.

Kev kho cua sov ntsig txog

Annealingntawm 4135 Alloy structural steel

Maj mam rhuab mus rau 850 degree thiab tso cai rau lub sij hawm txaus, cia cov hlau kom huv si, Tom qab ntawd maj mam txias hauv qhov cub rau 480 degree tom qab cua txias. 4135 alloy steel yuav tau MAX 250 HB (Brinell hardness).

Normalizing ntawm 4135 Alloy structural steel

Ua kom sov maj mam mus rau 850-880 degree, Cia li 2 teev.Ces cua txias.

Hardening ntawm 4135 Alloy structural steel

Tshav kub maj mam mus rau 870-890 degree , Tom qab txaus soaking ntawm no kub quench nyob rau hauv roj. Kub kom sai li sai tau thaum cov cuab yeej ncav cuag chav sov.

Tempering ntawm 4135 Alloy structural steel

Ua kom sov rau 400-565 degree, Khaws ntawm qhov kub li 2 teev rau 25 hli ntawm ntu, tom qab ntawd tso cua txias.

Mechanical Properties in Tempering Condition (18-22 HRC)

Ib qho ntawm qhov zoo ntawm AISI 4135 yog nws lub zog thiab quenchability. Cov khoom siv no tuaj yeem ua tiav qhov sib txawv ntawm qhov tawv tawv tom qab quenching thiab muaj kev hnav zoo thiab qaug zog. Tsis tas li ntawd, nws cov corrosion kuj thiab oxidation kuj zoo heev. Txawm li cas los xij, tseem muaj qhov tsis zoo rau AISI 4135 uas tau hais. Piv txwv li, nws cov tawv tawv yog qhov tsawg thiab tuaj yeem ua nkig hauv qhov chaw qis qis, thiab nws yuav raug oxidation ntawm qhov kub thiab txias.

Raws li rau nws cov kev siv, AISI 4135 steel yog dav siv nyob rau hauv kev tsim cov high-strength thiab hnav-resistant qhov chaw thiab Cheebtsam xws li high-strength bolts, shafts, zog, thiab sprockets. Tsis tas li ntawd, vim nws cov khoom siv zoo thiab kev tiv thaiv corrosion, AISI 4135 kuj tseem siv los tsim cov khoom thiab cov cuab yeej uas yuav tsum tau muaj zog dua, xws li cov khoom siv rau kev ua haujlwm kub thiab cov cuab yeej uas yuav tsum tau muaj kev ua haujlwm siab thiab ua haujlwm ntev.

Thoob ntiaj teb, ntau lub teb chaws muaj cov qhab nia zoo sib xws rau AISI 4135. Piv txwv li, hauv European EN tus qauv, cov qib sib xws rau AISI 4135 yog 1.7107 steel; nyob rau hauv Suav teb, raws li Suav teb chaws tus qauv GB / T 3077-2015, cov qib sib raug rau AISI 4135 yog 35CrMo steel. Cov kev sib raug zoo no pab txhawb kev sib txuas lus thiab kev koom tes ntawm ntau lub teb chaws kev lag luam thiab kev lag luam.

Zuag qhia tag nrho, AISI 4135 yog chromium-molybdenum alloy steel nrog lub zog siab, quenchability, thiab hnav tsis kam, feem ntau yog siv rau kev tsim khoom thiab cov khoom siv uas xav tau lub zog siab, hnav tsis kam, thiab corrosion kuj. Nws cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab kev siv sib raug rau cov qauv tshwj xeeb hauv ntau lub teb chaws, muab kev yooj yim rau kev koom tes thoob ntiaj teb thiab kev sib pauv. Txawm li cas los xij, vim nws qhov tsis zoo xws li tsis tshua muaj zog, yuav tsum tau saib xyuas txog nws qhov kev siv tau thaum siv.
