Mild Steel Plate EN steel grade S355NL material Supplier From India

What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel .

Cold rolled coil products EN steel grade S355NL material have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils with different surface roughness can be produced (glossy surface or matte surface, etc.).

EN steel grade S355NL material,Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.EN steel grade S355NL material
