Corrosion-resistant steel plate significantly improves the corrosion resistance of structural parts and prolongs the service life of structural parts. It can be used to make various structural parts that work in atmospheric environments and corrosive gases and liquids. Plate Corten B atmospheric corrosion resistant structural steel delivery status: According to performance and user needs, steel plates can be delivered in hot rolling, controlled rolling, normalizing, annealing, tempering, normalizing + tempering, quenching and tempering.
Our quality control department will do inspection for details of the steel materials Corten B atmospheric corrosion resistant structural steel before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
We have 4 typical production lines Corten B atmospheric corrosion resistant structural steel, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of Corten B atmospheric corrosion resistant structural steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in Corten B atmospheric corrosion resistant structural steel etc. steel is strictly controlled.
