Hot rolled steel coil sheet EN steel grade S450J0 material

ASTM A283 steel EN steel grade S450J0 material is a carbon steel plate used for general structural purposes. This steel has low strength and medium strength. It has two steel grades (C and D). For steel coils or unheated steel plates, additional stress relief tests should be carried out. Usually, inspections, inspections, and EN steel grade S450J0 material heat treatments should be carried out before leaving the factory after the coils are opened.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of EN steel grade S450J0 material steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main EN steel grade S450J0 material production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

The visual inspection (VI) or visual detection method is to scan the surface of the steel plate through a machine vision system (CCD line camera), convert the captured target into an image signal, and send it to a dedicated image EN steel grade S450J0 material processing system, which converts it into a digital signal based on pixel distribution and brightness, color and other information. The system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on the spot according to the result of the discrimination. Visual detection method can achieve online high-speed detection for the EN steel grade S450J0 material steel plate.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of EN steel grade S450J0 material etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in EN steel grade S450J0 material etc. steel is strictly controlled.

Our company will accept the product quality objection registration record, pass it to the EN steel grade S450J0 material production unit and relevant departments, and timely coordinate the supervision of product EN steel grade S450J0 material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
