The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the A709 grade 50W carbon steel plate material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this A709 grade 50W carbon steel plate steel grade.
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 A709 grade 50W carbon steel plate 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 A709 grade 50W carbon steel plate etc. steel is strictly controlled.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
