Kub ua hauj lwm cuab tam Steel H21 Round Bar

H21 cov cuab yeej kub ua haujlwm hlau tau lees paub los ntawm nws cov cua sov ua haujlwm zoo, hnav-tiv taus thiab ua haujlwm zoo heev, ua kom pom kev ruaj ntseg zoo hauv kev kho cua sov. Nws tseem muaj kev vam khom thaum kub txog li 650degree.H21 tshwj xeeb tshaj yog siv rau kub forging thiab blanking tuag thiab xuas nrig ntaus rau kev ua txiv ntseej, bolts thiab lwm yam khoom me me. Kev tsim cov tuag, shear hniav, kub extrusion tuag, mandrils, tuag tuav, thiab extrusion liners kuj tseem siv rau cov hlau no.
