The rectangular tube 50x30x2 6m Ст3пс5

Steel Ст3пс5 – instrumental, according to the degree of deoxidation semi-killed, the presence of nonmetallic inclusions of sulfur and phosphorus ≤ of 0.05% and 0.04% . According to GOST 27772-88 mechanical characteristics meet the construction of steel C245, used for construction, used as a loaded and welded nesvarenie elements, can work in freezing temperatures. Welded without restriction by any simple methods, you do not need to preheat the metal, during cooling of the weld in vivo microcracks are not formed. Not prone to placenow – violations of the integrity of the internal structure due to increased availability of carbon dioxide.

Used for the construction of arched beams of large span, works great on the bend, has the most optimal ratio of strength/unit weight. The deoxidation is performed by vacuum or by addition of silicon. Tests as performed by the manufacturer. The customer may require additional tests, the new settings appear in the contract for execution of works. Is made by rolling a round tube through rollers in rolling mills. Before applying for the warehouse party is visual and measuring control in accordance with the applicable quality indicators.
