Cov Lus Cim Tseem Ceeb:
Tag nrho peb cov S350GD galvanized steel daim hlau tuaj nrog daim ntawv pov thawj zeb kuaj (MTC) uas teev cov feem pua ntawm cov tshuaj lom neeg tiag tiag ntawm cov khoom siv - xyuas kom paub tseeb thiab ua raws li koj qhov kev xav tau EN 10346.
Lub luag haujlwm ntawm Txhua Lub Ntsiab Feem Xyuam hauv S350GD Kev Ua Haujlwm
Txhua qhov feem pua ntawm S350GD steel ua haujlwm rau lub hom phiaj tshwj xeeb, cuam tshuam ncaj qha rau nws cov khoom siv kho tshuab thiab kev siv tau:
1. Cov pa roj carbon (C): Tsawg dua lossis sib npaug li 0.12% - Lub zog muaj zog
Yog vim li cas qhov feem pua: Carbon tsim cov ntawv cog lus muaj zog nrog hlau los txhawb cov khoom muaj zog (tseem ceeb rau S350GD's Ntau dua lossis sib npaug rau 350MPa qhov xav tau). Capping ntawm 0.12% tiv thaiv cov brittleness ntau dhau, uas yuav ua rau cov hlau tawg thaum lub caij txias (xws li, khoov kab).
Kev cuam tshuam rau kev siv: Xyuas kom S350GD tuaj yeem tswj cov khoom thauj khoom yam tsis muaj kev cuam tshuam kev ua haujlwm - qhov tseem ceeb rau kev tsim kho thiab cov khoom siv tsheb.
2. Manganese (Mn): Tsawg dua lossis sib npaug li 1.60% - Toughness Enhancer
Yog vim li cas qhov feem pua: Manganese txhim kho lub zog tensile thiab toughness (pab S350GD tiv thaiv kev cuam tshuam los ntawm cua daj cua dub los yog txoj kev vibrations). Kev txwv rau 1.60% zam kom tsis txhob muaj kev sib tsoo- ntau dua Mn tuaj yeem ua rau tawg ntawm cov pob qij txha.
Kev cuam tshuam rau kev siv: Peb ib txwm 1.20-1.50% Mn ntau yam muab qhov sib npaug zoo ntawm lub zog thiab weldability rau cov khoom hnyav.
3. Phosphorus (P) & Sulfur (S): Tsawg kom ntseeg tau
Yog vim li cas tsawg feem pua: Ob leeg yog impurities. P (Tsawg dua lossis sib npaug li 0.035%) ua rau txias brittleness (kev pheej hmoo ntawm kev tawg ntawm qhov kub thiab txias), thaum S (Less dua los yog sib npaug rau 0.030%) ua rau "kub shortness" (cracking thaum vuam). Peb cov nqi qis dua (P: 0.020-0.030%, S: 0.010-0.020%) txo cov kev pheej hmoo no.
Kev cuam tshuam rau kev siv: Ua kom S350GD ua tau zoo nyob rau hauv ib puag ncig hnyav, los ntawm lub caij ntuj no khov rau cov txheej txheem vuam.
4. Silicon (Si): Tsawg dua lossis sib npaug li 0.50% - Lub zog & txheej pab
Yog vim li cas qhov feem pua: Silicon txhim khu lub zog thiab txhim kho zinc txheej adhesion (qhov tseem ceeb rau galvanized steel). Kev txwv rau 0.50% zam kom tsis txhob muaj qhov tsim nyog- Si ntau dhau ua rau cov hlau nyuaj rau thwj rau hauv cov duab nyuaj.
Kev cuam tshuam rau kev siv: Peb 0.20-0.40% Si ntau ua kom cov zinc txheej tsis tev, ncua kev pab cuam lub neej ntawm S350GD galvanized steel daim hlau.
5. Aluminium (Al): Ntau dua los yog sib npaug rau 0.020% - Cov Khoom Siv Ua Ntej
Yog vim li cas qhov feem pua: Aluminium refines lub steel lub grain qauv, ua txhua yam khoom (lub zog, elongation) uniform nyob rau hauv lub phaj. Peb 0.025-0.050% ntau yam ua kom cov nplej me me kom zoo dua toughness.
Kev cuam tshuam rau kev siv: Guarantee txhua feem ntawm S350GD phaj ua tau zoo ib yam - tseem ceeb rau cov khoom siv loj xws li lub ru tsev trusses.
Chemical Percentages cuam tshuam li cas S350GD's Mechanical Properties
Cov feem pua ntawm cov tshuaj lom neeg ntawm S350GD steel ncaj qha txhais rau nws cov khoom siv kho tshuab. Cov lus hauv qab no txuas cov ntsiab lus piv rau cov khoom tseem ceeb (siv GNEE Steel tus nqi ib txwm):
| Mechanical Property | EN 10346 Kev xav tau | Cov ntsiab lus tseem ceeb cuam tshuam rau nws | Qhov Feem Xyuam Pab Li Cas |
|---|---|---|---|
| Yield zog | Ntau dua lossis sib npaug li 350MPa | C (0.08-0.11%), Mn (1.20-1.50%) | C thiab Mn tsim cov ntawv cog lus muaj zog kom siab tshaj 350MPa yam tsawg kawg nkaus |
| Tensile zog | 410-550MPa | Mn (1.20-1.50%) | Mn boosts tensile muaj peev xwm mus rau 420-540MPa (peb ib txwm muaj) |
| Elongation | Ntau dua lossis sib npaug li 17% | P (0.020-0.030%), Al (0.025-0.050%) | Tsawg P txo qis brittleness; Al refines nplej rau 18-22% elongation |
| Lub zog cuam tshuam (0 degree) | Ntau dua lossis sib npaug li 27J | P (0.020-0.030%) | Tsawg P zam qhov txias brittleness, xa ntau dua lossis sib npaug rau 30J cuam tshuam lub zog |
