Nws suav nrog cov pa hlau, carbon-manganese steel, microalloed steel, tsawg-alloy high-zog hlau, thiab tsawg-hlau. Lub operating kub feem ntau los ntawm -20 degree rau 500 degree, thiab qee tus tuaj yeem ncav cuag 560 degree. Ntawm lawv, lub ntsiab yog hais txog 16mnr steel (16 manganese muaj peev xwm txo alloy steel, ib hom hlau), uas yog siv los tsim asme code siab cov hlab.
Siab txog ntsha hlau steel yog cov khoom siv tshwj xeeb ntsig txog kev lag luam hauv tebchaws thiab tib neeg lub neej, thiab yog cov khoom lag luam luv luv hauv kev lag luam metallurgical. Nyob rau hauv xyoo tas los, Tuam Tshoj cov boilers thiab siab cov hlab ntsha tsis tsuas yog qee cov khoom lag luam muaj cov khoom siv roj hmab thiab siab kuj hauv cov teb chaws tsim nyog ntawm kev ua kom zoo ntawm lub cev. Txog tam sim no, Tuam Tshoj tau tsim cov kab ke ntau lawm nrog cov nplai ntau lawm, nce ntxiv kev txhim kho cov phiaj ntau rau boilers thiab siab cov hlab ntsha.
