1.7228 Hlau

 

1.7228 steel (tseem hu ua SAE 4130) yog cov hlau tsis tshua muaj hlau, uas yog tus qauv los ntawm EN 10083-1. Cov hlau no tau zoo hardenability thiab weldability, thiab feem ntau yog siv nyob rau hauv aerospace, automotive, thiab mechanical engineering industries.

 

Cov tshuaj muaj pes tsawg leeg yog raws li nram no:

Cov pa roj carbon (C): 0 28-0.33 feem pua

Silicon (Si): 0 15-0.35 feem pua

Manganese (Mn): 0 40-0.60 feem pua

Phosphorus (P): siab tshaj 0.035 feem pua

Sulfur (S): siab tshaj 0.040 feem pua

Chromium (Cr): 0 80-1.10 feem pua

Molybdenum (Mo): 0 15-0.25 feem pua

 

Lub zog tensile ntawm cov hlau no yog 850-1000MPa, yield zog yog 460-570MPa, thiab elongation yog 20-30 feem pua.

 

Nws tuaj yeem nyob hauv lub xeev annealed lossis quenched.

 

Qhov zoo:

1. Zoo hardenability, muab zoo zog thiab toughness los ntawm kev kho cua sov;

2. Yooj yim rau vuam;

3. Zoo corrosion kuj.

 

Qhov tsis zoo:

1. Cov ntsiab lus carbon tsawg yuav ua rau qis zog;

2. Cov ntaub ntawv muaj feem yuav raug txwv los ntawm kev muaj peev xwm ntawm cov cuab yeej ua haujlwm.

 

Cov ntaub ntawv ntau tshaj plaws ntawm cov hlau no muaj xws li puag ncig bar, square bar, tiaj tiaj, thiab raj.

 

Kev sib piv ntawm cov qib hauv ntau lub teb chaws yog raws li hauv qab no:

Qib Suav: 1.7228

Qib Asmeskas: SAE 4130

German qib: 25CrMo4

Qib British: 708A25

Japanese qib: SCM430

 

Cov ntsiab lus:

1.7228 steel yog cov hlau tsis tshua muaj hlau nrog zoo hardenability thiab weldability, feem ntau siv hauv aerospace, automotive, thiab mechanical engineering industries. Cov hlau no muaj zog tensile thiab tawm los, zoo elongation, thiab zoo corrosion kuj. Txawm li cas los xij, nws cov ntsiab lus tsis tshua muaj carbon yuav ua rau cov nyhuv hardening qis dua, thiab nws cov ntaub ntawv feem ntau yuav raug txwv los ntawm kev ua cov cuab yeej muaj peev xwm.
