Corten B steel Surface Protection and Treatment Technology

Posted:2022-12-30 17:29:44

In order to ensure that the overall weather resistance of Corten B steel is consistent and avoid the decline in local corrosion resistance, a complete set of surface protection technology for Corten B steel has been formulated, that is, it is strictly forbidden to mix weather-resistant welding materials with ordinary welding materials, and arc strike plates and lead-out plates are strictly prohibited. And the horse board should use the same material steel plate as the base material.

Water-based pens should be used to mark the surface of Corten B steel, and grease, paint, welding spatter, etc. should be avoided on the components; the surface of polluted Corten B steel and weld seams should be polished; over-burning (<700°C) is strictly prohibited during heat correction ); For individual structures or weld reinforcements that may stagnate water, it is necessary to open process weep holes or smooth weld reinforcements to make it difficult to stagnate water.

After the welding and manufacturing of Corten B steel components, sand blasting treatment and then periodic watering treatment is beneficial to the accelerated formation of oxide layer on the surface of Corten B steel and weld seam, and the oxide layer is dense and uniform, which improves the weather resistance of Corten B steel.
