Cov keeb kwm keeb kwm ntawm carbon steel machined qhov chaw tuaj yeem nkag siab los ntawm ob qhov ntev: keeb kwm ntawm kev siv cov pa roj carbon steel thiab kev tsim cov tshuab machining.
Kev siv thaum ntxov thiab kev lag luam ntawm Carbon Steel
Raws li hom yooj yim tshaj plaws ntawm cov hlau, carbon steel tau ua cov khoom tseem ceeb hauv kev tsim khoom txij li Kev Lag Luam Kev Lag Luam hauv xyoo pua 19th. Nws muaj pes tsawg leeg yog hlau thiab carbon (feem ntau nrog cov ntsiab lus carbon tsawg dua lossis sib npaug li 2.1%), thiab muaj cov manganese, phosphorus, sulfur, thiab lwm yam, muab qhov zoo xws li tus nqi qis, yooj yim ntawm smelting, thiab kho cov khoom siv kho tshuab.
Los ntawm lig 19th mus rau thaum ntxov xyoo pua 20th, nrog rau maturation ntawm Bessemer converter thiab qhib -hearth steelmaking technology, carbon steel ua tiav loj- nplai ntau lawm thiab tau dav siv nyob rau hauv cov yam ntxwv Cheebtsam xws li shafts, zog, thiab bolts.
Los ntawm nruab nrab xyoo pua 20th, Tebchaws Asmeskas tau siv cov pa roj carbon steel hauv kwv yees li 87% ntawm nws cov hlau tsim. Vim nws qhov sib npaug ntawm lub zog, machinability, thiab kev lag luam, nws tau los ua "feem ntau machined steel."
