Rolling process of A573 Grade 58 carbon-manganese-silicon steel

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, A573 Grade 58 carbon-manganese-silicon steel and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

The quality of carbon steel is distinguished by the amount of sulfur (s) and phosphorus (P) in the steel. When the A573 Grade 58 carbon-manganese-silicon steel sulfur content in carbon steel is not more than 0.050% and the phosphorus content is not more than 0.045%, it is ordinary carbon steel; when the sulfur content and phosphorus content in carbon steel are less than 0.040%, it is high-quality carbon steel; when the A573 Grade 58 carbon-manganese-silicon steel sulfur content in carbon steel is less than 0.030% and the phosphorus content is less than 0.035%, it is high-quality carbon steel.

S355NC steel offers excellent bending, flanging, cold-bordering and folding A573 Grade 58 carbon-manganese-silicon steel properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

What is the difference between Q345B steel and Q345A steel?
A573 Grade 58 carbon-manganese-silicon steel, Q345B steel and Q345A steel have slight difference in chemical composition:
Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15;
Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15.
The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.

The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.

We are engaged in A573 Grade 58 carbon-manganese-silicon steel corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, A573 Grade 58 carbon-manganese-silicon steel ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.
