Q235NH weather resistant steel plate is currently a popular plate in building decoration engineering and product production. Generally, it refers to a plate that is resistant to corrosion and not easy to rust in weak corrosive media such as atmosphere and water vapor.
Q235NH weather resistant steel plate aging insulation: the aging should be carried out in strict accordance with the process requirements, and the insulation time should be appropriate to prevent under-aging or over-aging from causing insufficient hardness.
Before the Q235NH weather resistant steel plate is installed in the furnace, the special alloy and the ordinary alloy shall be installed separately for aging. When it is indeed necessary to age in the same furnace due to production reasons, the Q235NH weather resistant steel plate shall use the special alloy process for aging.
The hardness of Q235NH weather resistant steel plate is obtained according to the reasonable quenching process of people's water quenching line. This method can not only obtain higher hardness, but also maintain the lower alloy composition in the steel. The produced Q235NH weather resistant steel plate is easy to machine, bend and weld by electric welding.
