GB5310 20G seamless boiler steel yeeb nkab

Qib 20G Seamless Steel Boiler Pipe muaj feem xyuam rau cov raj seamless rau ua chav boiler uas nws lub siab yog siab lossis siab dua thiab seamless raj siv los ua cov kav dej.

20G seamless steel yeeb nkab yog cov khoom siv zoo carbon steel, cov khoom siv boiler, cov ntsiab lus carbon ntawm 0.17-0.24%, tensile lub zog ntawm 410Mpa, yield point 230-250Mpa. Yog peb cov khoom tseem ceeb ntawm cov hlau, peb tuaj yeem muab 20G Seamless yeeb nkab nrog cov khoom zoo thiab cov nqi sib tw. Ntawm no los qhia koj txog peb 20G seamless yeeb nkab cov khoom siv tshuaj lom neeg thiab cov khoom siv tshuab.
