Recovery of global corten steel S355J2G2W demand drives steel prices higher

corten steel S355J2G2W product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick corten steel S355J2G2W steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

Oxygen is a harmful element in corten steel S355J2G2W steel. With the increase of oxygen content, the strength of corten steel S355J2G2W steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of corten steel S355J2G2W steel.

ASTM A242, corten steel S355J2G2W used in marine and humid environments, is a high-strength, corrosion-resistant alloy with a yield strength of 42,000 to 50,000 psi and an allowable bending stress of 25,200 to 30,000 psi.
