A 691 1} / 2Crord41 Alloy Steel Yeeb Nkab
Ib qho 691 1} / 2cr cl cl41 alloy welded yeeb nkab yog lub chromium- molybdenum alloy thiab siab tau teev los ntawm American tus qauv.
Qeb 41 cov yeeb nkab steel yuav tsum tau sib xyaw kom sov rau qhov ntsuas kub thiab tsis tshaj qhov ua kom muaj qhov siab tshaj plaws hauv lub rooj 2, thiab tom qab ntawd huab cua- txias ntawm chav tsev kub. Tom qab ib txwm ua, cov yeeb nkab steel yuav tsum tau rov ua kom zoo dua rau qhov ntsuas kub yam tsawg kawg nkaus hauv cov lus 2 thiab khaws cia ntawm qhov ntsuas kub tsawg kawg 1/2 h / hauv.
[0.2hr / cm] thickness lossis 1 / 2h, qhov twg yog qhov ntau dua, thiab tom qab ntawd huab cua {{txias.
