nm400 equivalent material strength parameters

Q345qCNH grade is a weather-resistant structural steel for bridges. Bridge steel grade is Q345qC. It is produced by the standard GB / T714-2014. Weather-resistant bridge plate Q345qCNH is a kind of structural steel plate for bridge. Add a certain amount of alloy elements, such as P, Cr, Ni, Cu, Mo, etc. to the steel to form a protective layer on the surface of the metal substrate to improve the atmospheric resistance corrosive steel.

Specification range of available steel NM400 equivalent material: thickness ≤ 650mm, width ≤ 4500mm, length ≤ 18000mm. Larger specifications of steel plates are also available as required. Our steel plates NM400 equivalent material can be supplied according to Chinese standard, American Standard AISI / ASME / ASTM, Japanese JIS, German standard DIN, French NF, British BS, European EN, international ISO and other standards. Heat treatment process: controlled rolling, normalizing, tempering, normalizing plus tempering, quenching and tempering, etc.

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 NM400 equivalent material 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.
