GB Q420D GB / T 1591 steel hlau

GB Q420 D GB / T 1591 steel yog kev ua haujlwm siab qis alloy steel tsim los ntawm Suav kev lag luam steel. Nws yog tsim los ntawm manganese thiab silicon ua lub ntsiab alloying ntsiab. Cov hlau no muaj lub zog ntau dua rau qhov hnyav dua li ntau lwm cov hlau sib xws, ua rau nws tsim nyog rau ntau yam kev siv, suav nrog kev tsim kho, kev tsim nkoj, kev tsheb ciav hlau, thiab cua zog. Nws hnav thiab corrosion resistant zog kuj ua rau nws zoo tagnrho rau siv nyob rau hauv industrial thiab offshore daim ntaub ntawv. GB Q420 D GB / T 1591 steel yog dav siv nyob rau hauv Suav teb thiab tau txais kev muaj koob meej thoob plaws ntiaj teb.

Q420D yog cov hlau tsis tshua muaj siab zog steel phaj. Q420D steel phaj yog siv raws li cov txheej txheem tshwj xeeb ntawm GB / T1591.

4. Normalizing/normalizing dov yog: Q420NB, Q420NC, Q420ND, Q420NE.

5. Cov qib kub-kub Q420 series muaj xws li: Q420B, Q420C.

6. Cov khoom sib xyaw thiab cov khoom siv kho tshuab ntawm Q420C│Q420D│Q420E cov ntaub ntawv nyob rau hauv cov kev kho cua sov sib txawv tau piav qhia meej hauv GB / T 1591-2018 tus qauv, yog li lawv yuav tsis qhia ntawm no ib zaug.

7. Lub thickness ntawm Q420B│Q420C│Q420D│Q420E cov ntaub ntawv feem ntau yog 8 hli lossis ntau dua, qhov dav yog 1600mm lossis ntau dua, thiab qhov ntev yog 5000mm lossis ntau dua.

Q420D steel phaj yog dab tsi?
Ua ntej tshaj plaws, Q420D steel phaj yog qib qis-alloy high-strength steel phaj. Nws yog tsim los ntawm kev ntxiv me me ntawm cov ntsiab lus alloy rau steel. Nws yog siv rau ob hom steel phaj hauv kev tsim kho thiab engineering cov qauv. Qib Q420D steel phaj muaj npe tom qab lub phaj steel nrog lub zog tawm ntawm 420mpa. D txhais tau hais tias cov phaj hlau no tau dhau qhov cuam tshuam ntawm -40 degrees Celsius, thiab Q yog lub ntsiab lus ntawm lub zog tawm los.
Cov tshuaj muaj pes tsawg leeg ntawm Q420D steel phaj: C Tsawg dua lossis sib npaug rau 0.20 Si Less dua lossis sib npaug rau 0.50 Mn Tsawg dua lossis sib npaug rau 1.70 P Tsawg dua lossis sib npaug rau 0.035 S Tsawg dua lossis sib npaug rau 0.035 Nb Tsawg dua los yog sib npaug rau 0.07 V Less dua lossis sib npaug rau 0.20 Ti Less dua lossis sib npaug rau 0.20 Cr Less dua lossis sib npaug 0.30 Ni Tsawg dua lossis sib npaug 0.80 Cu Less dua lossis sib npaug 0.30 N Tsawg dua lossis sib npaug rau 0.015 Mo Less dua lossis sib npaug rau 0.20
Txhua yam khoom ntawm Q420D steel phaj Yield zog Ntau dua los yog sib npaug rau 340 Tensile lub zog 500-680 Elongation tom qab tawg Ntau dua los yog sib npaug rau 18 Kev cuam tshuam lub zog 34
Q420D steel phaj muaj cov cuab yeej zoo thiab kev sib txuas, zoo kub thiab txias ua haujlwm, thiab lub zog thiab tawv ntawm cov hlau tau txhim kho los ntawm kev ntxiv cov ntsiab lus alloying.

Kev qaug zog tsis kam: Ua kom muaj zog siab nyob rau hauv lub sij hawm ntev cyclic kev nyuaj siab, txo kev pheej hmoo ntawm qaug zog puas tsuaj.

Toughness: Txawm tias nyob rau hauv ib puag ncig uas tsis kub, Q420D tseem tuaj yeem tswj tau zoo toughness thiab plasticity, zam kev nyab xeeb xwm txheej los ntawm nkig puas.

Txias txoj kev ua tau zoo thiab vuam kev ua tau zoo: Kev ua haujlwm yooj yim thiab tsim khoom, tuaj yeem ua rau ntau yam duab thiab cov qauv los ntawm ntau yam kev ua haujlwm txias xws li khoov, shearing, xuas nrig ntaus, thiab lwm yam, thiab muaj kev ua haujlwm zoo heev.
