10S20 Dawb-txiav Steel Chemical Composition

 

Tshuaj muaj pes tsawg leeg:

 

Cov pa roj carbon C: {{0}}.07 txog 0.13

Silicon Si: Tsawg dua lossis sib npaug rau 0.40

Mn: 0.70 rau 1.10

Sulfur S: {{0}}.15 txog 0.25

Phosphorus P: Tsawg dua lossis sib npaug rau 0.06

Mechanical zog:

 

Tensile zog σb (MPa):

(kub dov) 390 ~ 540;

(txias kos) steel thickness los yog txoj kab uas hla:

8 ~ 20: 530 ~ 755;

> 20 ~ 30: 510 ~ 735;

> 30: 490 ~ 685

Elongation δ5 (%): (kub dov) Ntau dua lossis sib npaug 22; (txias dov) Ntau dua lossis sib npaug rau 7.0

Tshooj shrinkage ψ (%): (kub dov) Ntau dua lossis sib npaug rau 36

Hardness: (kub dov) Tsawg dua los yog sib npaug rau 170HB; (txias kos) 152 ~ 217HB

 

Kev nyab xeeb kuj yog qhov tseem ceeb tshaj plaws. Cov neeg ua haujlwm yuav tsum tau kawm txog kev siv tshuab kom raug thiab cov txheej txheem kev nyab xeeb. Cov cuab yeej tiv thaiv yuav tsum hnav txhua lub sijhawm kom tsis txhob raug mob.

 

Tsis tas li ntawd, kev khaws cia kom zoo thiab tuav ntawm 10S20 steel ua ntej thiab tom qab ua tiav yog qhov tseem ceeb los tiv thaiv kev puas tsuaj thiab xeb. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw qhuav thiab huv si thiab ua tib zoo saib xyuas kom tsis txhob khawb thiab dents.

 

Hauv kev xaus, kev ua 10S20 dawb-txiav steel yuav tsum tau ua tib zoo saib xyuas cov cuab yeej xaiv, machining tsis, daim ntawv thov coolant, kev kho cua sov, kev tswj kom zoo, kev ruaj ntseg, thiab cia. Los ntawm kev ua raws li cov lus qhia no, cov tuam txhab tsim khoom tuaj yeem ua kom muaj kev ua haujlwm zoo thiab tsim cov khoom lag luam zoo uas ua tau raws li qhov xav tau tshwj xeeb.
