2.} qib kev faib tawm
ASTM A210 / ASME SA210 muab A210 A1 A1 thiab A210 C Qib .
3.} Cov Tsim Khoom Raug
Cov khoom siv smelting: cov khoom lag luam tsim nyog yuav tsum tau calmer steel .
Kev tsim khoom: cov hlab yuav tsum yog tsim los ntawm kev ua haujlwm los ntawm kev ua haujlwm kub thiab ua haujlwm kub heev lossis ua haujlwm txias rau hauv qhov kev txiav txim {}}
Cov xwm txheej xa tawm: Cov raj kub dov tawm hauv lub xeev kub, txias cov kev sib tw, cov annealing lossis ib txwm muaj.
Cov kev kho deg: yog hais tias teev nyob rau hauv kev txiav txim, saum npoo ntawm lub raj steel yuav tsum raug pickled lossis rub mickled thiab txhaj tshuaj peed .
4.}} kev siv tshuaj lom neeg muaj pes tsawg leeg
Cov tshuaj lom neeg muaj pes tsawg leeg yuav tsum ua tiav cov kev xav tau ntawm cov kev qhia tshwj xeeb, thiab kev siv cov khoom lag luam theem pib tsis muaj npe nyob rau hauv qhov kev qhia tshwj xeeb yog tsis pub .
5.} Ua haujlwm ntsuas yuav tsum tau
Cov zis yuav tsum raug kuaj Tensile, cov kev ntsuas Flatness, Hydrostatic Test, Hydrostatics Truck yuav tsum tau ua txhaum kev cai, kev zam txim, vuam thiab khoov .
{{06. tensile thiab hardness yam khoom
Qhov tshwj xeeb muab lub tensile thiab hardness cov khoom, tab sis tsuas yog rau qee qhov kev txwv loj
