1.7225 Nws

 

1.7225 steel qauv yog EN 10083-3. Nws yog lub zog muaj zog alloy cov qauv hlau nrog cov khoom siv zoo heev thiab hnav tsis kam.

 

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

Cov pa roj carbon (C): 0 38-0.45 feem pua

Silicon (Si): siab tshaj 0.40 feem pua

Manganese (Mn): 0 60-0.90 feem pua

Phosphorus (P): siab tshaj 0.035 feem pua

Sulfur (S): 0 020-0.040 feem pua

Chromium (Cr): 0 90-1.20 feem pua

Molybdenum (Mo): 0 15-0.30 feem pua

Boron (B): 0 0005-0.0030 feem pua

 

Lub zog tensile ntawm cov hlau no yog 850-1000MPa, lub zog tawm los yog 650-900MPa, thiab qhov elongation ntawm tawg yog ntau dua lossis sib npaug li 14 feem pua.

 

1.7225 steel feem ntau yog siv los tsim cov khoom muaj zog xws li crankshafts, bearings, txuas rods, thiab gears.

 

Cov hlau no tuaj yeem muab tshem tawm lossis quenched.

 

Qhov zoo:

1. Muaj zog thiab hardness;

2. Zoo hnav tsis kam thiab qaug zog lub zog.

 

Qhov tsis zoo:

1. Nyuaj rau lub tshuab thiab cua sov kho;

2. Qee zaum, lwm cov ntaub ntawv yuav raug siv los them rau nws qhov tsis muaj zog.

 

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

 

Kev sib piv ntawm cov qib hauv ntau lub teb chaws:

Suav qib: 42CrMo

Qib Asmeskas: SAE 4140, ASTM A29 / A29M-04

German qib: 1.7225

Japanese qib: SCM440

 

Nyob rau hauv cov ntsiab lus, 1.7225 steel yog ib tug high-strength alloy structural steel nrog zoo hnav tsis kam, uas yog tsuas yog siv los tsim cov khoom muaj zog. Txawm li cas los xij, nws qhov tsis zoo suav nrog kev nyuaj hauv kev siv tshuab thiab kev kho cua sov, thiab tsis tshua muaj zog, uas yuav tsum tau xav txog. Cov ntaub ntawv ntau tshaj plaws ntawm cov hlau no muaj xws li cov hlau puag ncig, square steel, tiaj tus hlau, thiab steel daim hlau. Kev sib piv ntawm cov qib hauv ntau lub teb chaws suav nrog qib Suav 42CrMo, Asmeskas qib SAE 4140 thiab ASTM A29/A29M-04, German qib 1.7225, thiab qib Japanese SCM440.
