Hot Rolled Square Tube

Hot-rolled steel pipe is a manufacturing process that processes a billet at high temperature to deform it into a tubular shape, and then obtains the final product through subsequent processes such as cooling and processing. Hot-rolled steel pipe has high strength and corrosion resistance, and is widely used in petroleum, natural gas, chemical industry, construction, machinery and other fields. Its main features include: smooth surface, precise size, high temperature resistance, corrosion resistance, high compressive strength, etc. The manufacturing process of hot-rolled steel pipe is simpler and more efficient than cold-rolled steel pipe, so the cost is relatively low.

Hot-rolled steel pipes are used for steel pipes. Hot rolling is relative to cold rolling. Cold rolling is rolling below the crystallization temperature, and hot rolling is rolling above the recrystallization temperature.
