ASTM A36 Hlau

 

ASTM A36 yog cov pa roj carbon steel raws li American Society for Testing and Materials (ASTM) tus qauv, uas muaj cov cuab yeej zoo thiab kev ua haujlwm thiab tau siv dav hauv ntau yam kev tsim kho thiab kev tsim khoom.

 

Tus Qauv Ua Haujlwm: ASTM A36

 

Chemical composition range:

Cov pa roj carbon (C): 0.25% - 0.35%

Silicon (Si): Tsawg dua lossis sib npaug rau 0.30%

Manganese (Mn): 0.60% - 1.00%

Phosphorus (P): Tsawg dua lossis sib npaug rau 0.04%

Sulfur (S): Tsawg dua lossis sib npaug rau 0.05%

 

Tshuaj muaj pes tsawg leeg:

Cov tshuaj muaj pes tsawg leeg ntawm ASTM A36 feem ntau suav nrog carbon (C), silicon (Si), manganese (Mn), phosphorus (P) thiab sulfur (S). Ntawm lawv, carbon yog lub ntsiab ntawm cov hlau, uas yuav ua rau kom lub zog thiab hardness ntawm hlau; silicon tuaj yeem txhim kho lub zog thiab hardness ntawm cov hlau thaum txo nws cov plasticity thiab toughness; manganese tuaj yeem ua kom lub zog thiab hardness ntawm hlau thaum txhim kho nws cov toughness; phosphorus thiab sulfur yog cov khoom tsis zoo thiab yuav tsum tau txo kom ntau li ntau tau.

 

Mechanical zog:

ASTM A36 muaj cov khoom siv zoo. Nws lub zog tensile feem ntau yog nruab nrab ntawm 35000 - 55000psi, yield zog yog nruab nrab ntawm 20000 - 27000psi, elongation yog nruab nrab ntawm 22% - 30%, thiab seem shrinkage yog nruab nrab ntawm 4% - 7%. Lub hardness yog nyob nruab nrab ntawm 70 - 90HRB. Cov nqi tshwj xeeb yuav txawv nyob ntawm qhov kev kho cua sov thiab kev ua haujlwm.

 

Qhov zoo:

1. Siab zog thiab hardness, nrog zoo hnav tsis kam thiab qaug zog kuj.

2. Kev ua haujlwm zoo, tuaj yeem nqa tawm shearing, stamping, txiav, khoov thiab lwm yam txheej txheem.

3. Kev ua haujlwm vuam zoo, tuaj yeem siv cov pa roj carbon arc vuam, roj tiv thaiv vuam thiab lwm yam kev siv vuam rau vuam.

4. Zoo corrosion kuj, tuaj yeem tswj kev ruaj ntseg hauv qhov chaw ntub dej.

 

Qhov tsis zoo:

1. Piv nrog rau lwm cov hlau alloy siab heev, ASTM A36 muaj kev ua haujlwm tsis zoo ntawm qhov kub thiab txias thiab nws yooj yim rau nkag thiab so.

2. Nyob rau hauv ib puag ncig kub, lub zog thiab hardness ntawm ASTM A36 yuav txo qis, thiab yooj yim tshwm sim deformation thiab puas.

3. Kev txiav cov txheej txheem ntawm ASTM A36 yog qhov tsis zoo, uas yuav tsum muaj kev ua haujlwm ntau dua.

 

Kev siv:

ASTM A36 feem ntau yog siv hauv cov txuas hniav, tsev, tsheb, nkoj tsim, tshuab tsim thiab lwm yam. Nws yog dav siv rau kev tsim ntau yam fasteners xws li bolts, ceev, rivets, kav thiab lwm yam fasteners, thiab kuj siv rau kev tsim ntau yam phaj, profiles, yam ntxwv thiab lwm yam. Tsis tas li ntawd, ASTM A36 tuaj yeem ua tiav kev kho mob saum npoo xws li zinc plating, chromeplating los txhim kho nws cov corrosion kuj thiab zoo li zoo thaum lub sij hawm tsim khoom.
