Kub Rolled St 37-2 A36 Mild Carbon Steel Phaj

Feem ntau muaj qhov sib txawv hauv qab no ntawm St37-2 thiab A36 cov ntaub ntawv:

 

I. Tshuaj muaj pes tsawg leeg

 

Cov ntsiab lus carbon:

 

Cov ntsiab lus carbon ntawm St {{0}} yog qhov qis, feem ntau qis dua 0.17%. Qhov qis carbon cov ntsiab lus ua rau cov hlau zoo dua vuam kev ua tau zoo thiab toughness.

Cov ntsiab lus carbon ntawm A36 yog me ntsis siab dua, txog 0.25%. Cov ntsiab lus carbon ntau dua yuav ua rau lub zog ntawm cov hlau mus rau qee qhov, tab sis nws yuav muaj qee yam cuam tshuam rau kev ua haujlwm vuam thiab toughness.

 

Manganese cov ntsiab lus:

 

Cov ntsiab lus manganese hauv St {{0}} feem ntau yog nruab nrab ntawm 0.40% thiab 1.20%. Manganese keeb pab txhim kho lub zog thiab toughness ntawm hlau.

Cov ntsiab lus ntawm manganese ntawm A36 kuj nyob rau hauv ib qho zoo sib xws, tab sis nws yuav txawv me ntsis. Cov ntsiab lus manganese tshwj xeeb yuav txawv nyob ntawm cov chaw tsim khoom thiab cov txheej txheem tsim khoom.

 

Lwm yam ntsiab lus:

 

Ob qho khoom siv kuj muaj me me ntawm cov khoom xws li silicon, sulfur, thiab phosphorus. Cov ntsiab lus ntawm cov ntsiab lus no tseem yuav cuam tshuam rau kev ua haujlwm ntawm cov hlau.

Piv txwv li, cov ntsiab lus siab ntawm sulfur thiab phosphorus ntau dhau yuav txo qhov toughness thiab vuam kev ua tau zoo ntawm cov hlau. St37-2 thiab A36 feem ntau nruj me ntsis tswj cov ntsiab lus ntawm leej faj thiab phosphorus kom ntseeg tau cov hlau zoo.

 

II. Mechanical zog

 

Lub zog:

 

Lub zog tawm los ntawm A36 feem ntau yog nyob ib ncig ntawm 250 MPa, thiab lub zog tensile nyob nruab nrab ntawm 400 thiab 550 MPa.

Lub zog tawm los ntawm St37-2 yog qhov qis, txog 235 MPa, thiab lub zog tensile yog nyob nruab nrab ntawm 360 thiab 510 MPa.

 

Toughness:

 

Vim tias cov ntsiab lus qis dua, St37-2 feem ntau muaj qhov tawv tawv zoo dua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qis. Nws tuaj yeem tiv taus qhov cuam tshuam thiab tawg rau qee yam.

Lub toughness ntawm A36 kuj zoo, tab sis tej zaum nws yuav qis me ntsis rau St 37-2. Hauv qee daim ntawv thov uas yuav tsum tau ua kom muaj zog, St37-2 yuav muaj qhov zoo dua.

 

 

III. Siv

 

Kev tsim vaj tsev:

 

A36 yog dav siv nyob rau hauv lub tsev tsim xws li steel beams, steel kem, thiab steel daim hlau. Nws lub zog thiab toughness tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm feem ntau cov qauv tsim.

St37-2 kuj tseem siv tau rau hauv kev tsim vaj tsev, tab sis qee lub sijhawm uas yuav tsum muaj kev ua haujlwm siab thiab kev sib tw, xws li txuas hniav thiab cov tsev siab siab, nws yuav nrov dua.

Mechanical manufacturing:

 

Ob qho khoom siv tuaj yeem siv rau hauv kev tsim khoom siv tshuab, xws li kev tsim khoom siv tshuab thiab ntim khoom. Vim nws lub zog ntau dua, A36 yog qhov tsim nyog rau cov khoom siv kho tshuab uas dais loj.

St37-2 yog qhov tsim nyog rau kev tsim cov khoom siv kho tshuab xws li cov hlab ntsha siab thiab cov kav dej uas muaj cov kev xav tau siab dua rau kev ua tau zoo thiab kev ua haujlwm vuam.

 

Shipbuilding:

 

Ob lub A36 thiab St37-2 muaj qee yam kev siv hauv kev tsim nkoj. A36 tuaj yeem siv rau cov qauv hull thiab qee qhov chaw ntawm cov nkoj.

Vim nws txoj kev vuam zoo thiab kev ua haujlwm zoo, St37-2 yog qhov tsim nyog rau cov qauv welded ntawm cov nkoj thiab qee qhov uas yuav tsum tau ua kom muaj zog.
