We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product Q355GNH corten steel sheet plate material annual capacity is 200 thousand tons.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
Vanadium mainly exists in the form of carbide in Q355GNH corten steel sheet plate material and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
ASTM A 242 GR. 1 steel plate, Q355GNH corten steel sheet plate material, A 242 GR. 1 steel plate, under ASTM standard, we can regard A 242 GR. 1 steel plate as Steel Resistant to Atmospherical Corrosion A 242 GR. 1 steel plate is one mainly of Steel Resistant to Atmospherical Corrosion, A 242 GR. 1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
