Longitudinal 16mn material belongs to high strength low alloy structural steel, carbon content of 0.1% -0.25%, adding the main alloying elements manganese, silicon, vanadium, niobium and titanium. 16mn is currently China's most widely used low-alloy steel. 16mn Longitudinal production process is the core of welding, especially high-quality oil and gas pipe, high quality requirements, welding capacity, thus ensuring excellent welding quality requirements while improving welding efficiency as possible. Submerged arc welding process mainly produces large diameter, thick-walled welded pipe, ERW process mainly produces small diameter thin-walled welded pipe, high-frequency welded pipe apparent size relative SAW straight seam steel pipe more sophisticated. Wide range for steel structures, piling, fluid transport, long-distance pipelines and other places.
