The strict quality control of EN steel grade S275N material processing

BBNsteel is a well known EN steel grade S275N material products stockist in China. Our S335N plate is weldable fine grain steel which comes under EN 10025-3 standard. S335N steel plates are with specified minimum strength at temperature of 275 mpa, and with a specific minimum value of impact energy. These fine grain steel is available in different shapes like plates, flats, bars and sections.

Over the years, the company has established a standard of EN steel grade S275N material steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to EN steel grade S275N material quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled EN steel grade S275N material products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the EN steel grade S275N material rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

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 S275N 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 S275N material etc. steel is strictly controlled.
