SA588 Gr B carbon steel plate sheet Typical Application

After adding phosphorus, copper, chromium, nickel and other trace elements to the steel, a dense and highly adherent protective film is formed on the surface of the steel, which hinders the spread and development of rust and protects the substrate under the rust layer to slow down its corrosion rate. The amorphous spinel-type oxide layer with a thickness of about 50μm-100μm formed between the rust layer and the substrate is dense and has good adhesion to the substrate metal.

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and SA588 Gr B carbon steel plate sheet resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, SA588 Gr B carbon steel plate sheet new materials, and promotes the competition of enterprises Struggle.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick SA588 Gr B carbon steel plate sheet steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

SA588 Gr B carbon steel plate sheet, EN 10025 E355 steel plate / sheet is suitable for general building steel. Chemical composition and mechanical properties of EN 10025 E355 steel. EN 10025 E355 steel conforms to EN 10025 standard, equivalent to DIN 17100: ST60-2, NFA: a60-2, UNI 7070: FE590 steel grade.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
