Welcome to Henan BBN Steel
In the preparation of groove, the groove preparation of en10025 s355j2 thick plate should be processed by mechanical groove machine first, so as to avoid flame cutting, so as not to lead to repeated heat in the welding part.Reasonable groove Angle is established to reduce the groove size as far as possible while meeting the weld connection strength, so as to achieve the purpose of reducing the amount of weld deposited metal filling.In the groove machining process, the deviation of groove Angle and blunt edge dimension should be restricted strictly according to the established requirements.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and en10025 s355j2 heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported en10025 s355j2 to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, en10025 s355j2, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
