Q310NQL2 corten steel delivery status

Q310NQL2 cold-rolled steel sheet and steel strip should be delivered in annealed flat state.

For new varieties of atmospheric corrosion-resistant steel, indoor accelerated corrosion tests (periodical dip corrosion tests, etc.) and atmospheric exposure tests under various climatic and environmental conditions should be carried out.
