Q235 A36 H Channel Steel

1, tus txheej txheem formulation tog yog txawv

A36 yog cov khoom siv ntawm Asmeskas tus qauv ASME tus qauv (sib npaug rau ASTM specification), SS400 yog cov khoom siv ntawm Japanese tus qauv JIS G3101 (dov hlau rau cov qauv zoo tib yam), thiab Q235 yog cov khoom ntawm lub teb chaws tus qauv GB / T700 tus qauv.

2, cov ntsiab lus ntawm Mn keeb hauv A36 tsis siv vim yog lub thickness ntawm lub phaj (los yog txoj kab uas hla ntawm cov hlau puag ncig), thiab cov ntsiab lus hauv qab 20mm tsis muaj Mn. Q235 yuav tsum muaj cov ntsiab lus ntawm C, Si, Mn, S, P thiab lwm yam, tab sis SS400 tsuas yog xav kom S thiab P tsawg dua 0.050, thiab lwm yam yuav tsum tsis txhob ua. Tshuaj muaj pes tsawg leeg ntawm peb:

①Q235 qib A, B, C, D (GB/T 700-2006)

Qib Q235A muaj C 0. }%S Tsawg dua lossis sib npaug rau 0.050P Tsawg dua lossis sib npaug rau 0.045

Qib Q235B muaj C 0.12-0.20%Mn 0.30-0.70%Si Tsawg dua lossis sib npaug rau { {11}}.30%S Tsawg dua lossis sib npaug li 0.045p Tsawg dua lossis sib npaug rau 0.045 (nrog kev pom zoo los ntawm tus neeg thov, cov ntsiab lus carbon yuav tsis ntau dua 0.22%)

Qib Q235C muaj C Tsawg dua lossis sib npaug rau 0.18% Mn 0.35-0.80% Si Less dua lossis sib npaug rau 0.3 0%S Tsawg dua lossis sib npaug rau 0.040p Tsawg dua lossis sib npaug rau 0.040

Qib Q235D muaj C Tsawg dua lossis sib npaug rau 0.17% Mn 0.35-0.80% Si Less dua lossis sib npaug rau 0.3 0 %S Tsawg dua lossis sib npaug rau 0.035p Tsawg dua lossis sib npaug rau 0.035

②ASTM 36 muaj C Tsawg dua lossis sib npaug rau 0.26%P Tsawg dua lossis sib npaug rau 0.04%S Tsawg dua lossis sib npaug rau 0.05% Si Less dua los yog sib npaug li 0.40%

Cu (thaum tooj liab tau teev tseg) Ntau dua lossis sib npaug rau 0.20%

③SS400 muaj S Tsawg dua lossis sib npaug rau 0.050% thiab P Tsawg dua lossis sib npaug li 0.050%

3. Cov khoom siv sib txawv ntawm cov khoom siv:

① Lub zog tensile ntawm A36 yog 58 ~ 80 Ksi (li 400 ~ 550MPa). Lub zog tawm los yog 36 Ksi (txog 250MPa).

Lub zog tensile ntawm Q235 yog 370 ~ 500 MPa, thiab lub zog tawm los yog 235MPa

Lub zog tensile ntawm SS400 yog 400 ~ 510 MPa, thiab lub zog tawm los yog 245MPa.

4. (Cov khoom siv kho tshuab ntawm SS400 thiab Q235 yog tag nrho raws li steel phaj thickness tsawg dua 16mm.) Raws li tuaj yeem pom los ntawm cov ntaub ntawv saum toj no, ASME tus qauv A36 thiab Tuam Tshoj tus qauv Q235 cov ntaub ntawv muaj npe tom qab lub zog ntawm cov khoom siv, thaum SS400 muaj npe tom qab lub zog tensile ntawm cov khoom. Los ntawm kev txheeb xyuas cov cuab yeej cuab tam ntawm cov khoom, A36 yog sib npaug rau SS400, thaum Q235 yog qhov phem dua.

5, A36, SS400 thiab Q235 hloov pauv: txawm hais tias cov khoom siv hluav taws xob ntawm Q235 yog qhov phem dua li cov ntaub ntawv A36 thiab SS400, nyob rau hauv cov txheej txheem ua haujlwm tiag tiag, tsuav yog tsis muaj qhov xav tau meej, feem ntau peb cov ntaub ntawv siv tau rau ib leeg. .
