Welding technology of Q295GNH, Q310GNH, Q355NH corten steel

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This Q295GNH, Q310GNH, Q355NH corten steel rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Q295GNH, Q310GNH, Q355NH corten steel, Wear-resistant steel plate has good heat resistance:
The alloy wear-resistant layer is recommended to be used under ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high temperature wear of ≤800℃. The recommended operating temperature is as follows: Ordinary carbon steel base plate is recommended to be used in working conditions not higher than 380℃; Low-alloy heat-resistant steel plates (15CrMo, 12Cr1MOV, etc.) substrates are recommended to be used in working conditions not higher than 540℃; The heat-resistant stainless steel substrate is recommended to be used at no higher than 800℃.
