• Cov pa roj carbon (c):Cov pa roj carbon yog ib qho tseem ceeb tshaj plaws uas cuam tshuam lub zog thiab hardness ntawm cov hlau. Nyob rau hauv qib B, cov ntsiab lus ntawm cov roj carbon tsawg kom zoo weldability thiab formability, ua rau nws haum rau ntau cov ntawv thov.
• Manganese (MN):Manganese txhim kho lub zog thiab tawv ntawm cov hlau thaum tseem txhim kho nws txoj kev tiv taus hnav thiab kua muag. Nws kuj tseem pab txhawb kom txo tus brittleness ntawm cov hlau.
• Phosphorus (p):Phosphorus tau khaws cia raws qib qis kom txo qis kev pheej hmoo ntawm brittleness thiab kev tawg, tshwj xeeb tshaj yog thaum lub sij hawm vuam thiab tsim cov txheej txheem.
• Sulphur (s):Zoo ib yam li phosphorus, leej faj yog tswj hwm mus rau theem qis kom tsis txhob muaj cov teeb meem xws li kub thiab nquag tawg thaum lub sij hawm kub ua haujlwm).
• Tooj liab (Cu):Tooj liab tuaj yeem raug ntxiv rau txhim kho corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv ib cheeb tsam uas cov hlau yuav raug rau cov xwm txheej hnyav. Qhov no yog ib qho yuav tsum tau ua thiab yuav tsum tau teev nyob hauv kev xaj khoom.

Cov tshuaj lom neeg noua haujlwm ua ke los muab qib b steel nrog kev sib npaug ntawm lub zog, ductility, thiab weldability,Ua rau nws muaj ntau yam khoom rau cov ntawv thov cov qauv.

ASTM A500 qib B Hlau Tubing yog paub rau cov khoom siv ARTM A5Ses kom ntseeg tau tias yog cov khoom siv tseem ceeb thiab ua kom muaj kev tswj hwm thaum tswj cov kev ua kom muaj formability thiab weldability. Kev sib xyaw ua ke ntawm lub zog thiab ductility ua rau nws zoo tagnrho rau cov ntawv thov xws li cov thav duab, yob tawb, thiab lwm yam txheej txheem txheej txheem.

• Kev Ntsuas Hluav Taws Xob Ntsuas thiab Lub Zog:

Qib B muaj kev sib npaug zoo ntawm formability thiab lub zog. Nws muaj lub zog tsawg kawg ntawm 58, 000 psi (400 mpa) thiab tsawg kawg yog psi}} psi (290 mpa). Qhov kev sib xyaw no ntawm cov khoom ua rau nws haum rau ntau cov ntawv thov cov txheej txheem uas yuav tsum muaj tab sis cov khoom siv tseem yuav tsum tau ua haujlwm.

• Versatility hauv cov ntawv thov:

Vim nws cov khoom sib npaug, qib b yog veratile thiab tuaj yeem siv rau ntau txoj kev tsim kho thiab kev tsim khoom. Nws yog feem ntau siv nyob rau hauv kev tsim cov thav duab, txuas ntxiv hauv cov ntawv thov uas xav tau kev ua tau zoo tab sis lub zog siab tshaj plaws yog tsis tsim nyog. Cov versatility no ua rau nws xaiv qhov kev xaiv zoo tshaj rau ntau tus kws tshaj lij engineers thiab cov neeg tsim qauv.

• Zoo weldability:

ASTM A500 qib b hlau tubing tau zoo weldability, uas yog qhov tseem ceeb rau ntau yam kev tsim kho thiab kev tsim kho cable. Nws cov pa roj carbon thiab manganese cov ntsiab lus tseeb tias nws tuaj yeem yooj yim welded yam tsis muaj kev pheej hmoo yooj yim los yog lwm txoj kev sib tw vuam. Qhov no ua rau nws yooj yim dua ua haujlwm nrog thiab txo lub sijhawm thiab tus nqi cuam tshuam nrog kev ua kom zoo nkauj.

• Zoo Formability:

Qib B Obleck tubing yog yooj yim rau daim ntawv, txiav, thiab tshuab, ua rau nws haum rau ntau yam txheej txheem. Cov ntaub ntawv no tso cai rau nws siv rau hauv cov ntawv thov uas xav tau khoov lossis lwm yam kev ua haujlwm.

• Nqi-txiaj ntsig:

Piv rau cov qhab nia siab dua xws li qib C thiab D, qib B feem ntau tau them tus nqi rau ntau cov ntawv thov. Qhov no ua rau nws xaiv kev lag luam rau cov phiaj xwm uas tsis tas yuav muaj zog tshaj plaws, tso cai rau cov qauv txuag yam tsis muaj kev cuam tshuam cov qauv txheej txheem.

• Muaj Txaus:

Qib B yog dav nyob rau hauv kev ua lag luam, uas yog lwm qhov laj thawj rau nws muaj koob meej. Nws cov kev siv ntau txhais tau tias nws yog cov khoom siv tau yooj yim los ntawm cov neeg muab khoom, kom ua tau yooj yim rau cov phiaj xwm uas tsis muaj cov hmoov txhuas ua tau ntev. Qhov kev muaj feem ntau yog qhov tshwj xeeb rau cov phiaj xwm loj-ntsuas uas cov khoom xa tuaj yog qhov tseem ceeb.

Hauv cov ntsiab lus, qib B yog feem ntau siv steel 500 vim nws cov khoom siv sib npaug, cov nqi zog hauv cov ntawv thov, muaj peev xwm tiv thaiv dav, thiab kev ua kom zoo. Cov yam ntxwv no ua rau nws xaiv tau thiab muaj txiaj ntsig zoo rau ntau cov ntawv thov kev tsim qauv.
