Qhov sib txawv ntawm LTCS thiab Carbon steel
Tsawg-kub carbon steel yog tsuas yog siv nyob rau hauv cov khoom uas tsis muaj kub, tshwj xeeb tshaj yog welded siab hlab ntsha.
Lawv muaj cov pa roj carbon tsawg rau nruab nrab ({{0}}.20 rau 0.30%), siab manganese (0.70 txog 1.60%), silicon ( 0.15 mus rau 0.60%) steels tus yam ntxwv los ntawm ib tug zoo grain qauv thiab uniform carbide faib. Lawv muaj lub zog nruab nrab thiab tawv tawv mus rau - 50 degree F (-46 degree).
Txhawm rau txhim kho cov nplej thiab txhim kho formability thiab weldability, carbon steel tuaj yeem muaj {{0}}.01% rau 0.04% niobium. Paub tias yog columbium steels, lawv yog siv los ua shafts, forgings, zog, tshuab qhov chaw, tuag thiab ntsuas. Txog li 0.15% sulfur lossis 0.045% phosphorus ua rau lawv yooj yim dua txiav tab sis txo lub zog.
LTCS yog nickel-based alloy steel phaj tshwj xeeb tsim los rau cov ntawv thov cryogenic mus rau -150 degree F. Feem ntau yog siv rau kev tsim kho qhov kub thiab txias ntawm cov khoom siv hluav taws xob tsawg hauv cov nroj tsuag tshuaj hauv qab -55 degree .
Cov pa roj carbon steel feem ntau nyob ntawm nws lub cev lub cev thiab cov qauv nplej. Cov pa roj carbon steel kav muaj cov ntsiab lus carbon ntau dua li cov hlau tsis tshua muaj kub, cov pa roj carbon tsawg lossis lwm cov pa roj carbon steel. Hom hlau tshwj xeeb no muaj zog thiab ruaj khov dua thiab feem ntau siv rau ntau yam haujlwm.
