QT EN steel grade S460NL material specification

Advantages of EN steel grade S460NL material: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.

EN steel grade S460NL material Flaw detection standard: our steel plates can be produced and inspected in accordance with China (JB4730, GB/T2970), the United States (A435, A577, A588), Japan (JIS G0801, JIS G0901), Germany (SEL072), Britain (BS5996), France (NFS04-305) and other domestic and foreign flaw detection standards. Delivery status: according to the user's requirements, EN steel grade S460NL material can be delivered in hot rolling, normalizing, tempering, normalizing and tempering, quenching and tempering, etc.

The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as EN steel grade S460NL material.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of EN steel grade S460NL material, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
