Tab sis dab tsi yog carbon steel yeeb nkab, tiag tiag? Nws ua li cas, thiab vim li cas nws thiaj li yog qhov kev xaiv zoo tshaj plaws rau engineers thiab project managers thoob plaws kev lag luam? Hauv tsab xov xwm no, peb yuav tshawb xyuas txhua yam ntawm cov kav dej carbon steel - lawv cov khoom, qib, kev siv, thiab cov qauv tsim khoom.
Hauv cov ntsiab lus yooj yim,carbon steel yeeb nkabhais txog ib hom yeeb nkab steel uas feem ntau muaj hlau thiab carbon, nrog rau cov kab ntawm lwm cov ntsiab lus xws li manganese, sulfur, thiab phosphorus. Nws lub zog, durability, thiab nqi -kev ua tau zoo ua rau nws yog ib qho ntawm cov khoom siv txhim khu kev qha tshaj plaws rau kev tsim kho, tshuab, thiab kev thauj mus los. Raws li cov ntsiab lus ntawm cov pa roj carbon monoxide thiab cov txheej txheem tsim khoom, cov kav dej carbon steel tuaj yeem muab faib ua cov qib sib txawv, txhua tus tsim los rau ib puag ncig tshwj xeeb thiab kev ua tau zoo.
Dab tsi txhais cov Carbon Steel Pipe thiab Nws Li Cas?
Dab tsi yog cov ntsiab lus muaj nyob hauv carbon steel? Dab tsi txiav txim siab nws qib? Cov pa roj carbon ntau cuam tshuam li cas cov yeeb nkab ua haujlwm?
Cov pa roj carbon steel yog txhais los ntawm nws cov ntsiab lus carbon - feem ntau ntawm 0.05% thiab 2.0% los ntawm qhov hnyav. Lwm cov ntsiab lus xws li manganese, silicon, thiab tooj liab yuav raug ntxiv rau hauv me me los txhim kho qee yam khoom. Raws li carbon concentration, carbon steel kav feem ntau muab faib ua peb pawg:
| Hom | Cov ntsiab lus carbon (%) | Cov yam ntxwv tseem ceeb | Cov ntawv thov siv |
|---|---|---|---|
| Tsawg Carbon (Mild Steel) | < 0.25 | Ductile, yooj yim rau weld thiab tsim | Kev tsim kho, kev kav dej dav dav |
| Nruab nrab Carbon | 0.25–0.60 | Sib npaug zog thiab hardness | Machinery, structural applications |
