What is chemical composition and mechanical properties of SA573 Gr 70 carbon steel material

With high-quality SA573 Gr 70 carbon steel material steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our SA573 Gr 70 carbon steel material steel market and improved the control of steel plate production quality.

Our company has long been engaged in high-strength wear-resistant plate products of various materials such as nm400 wear-resistant steel, nm450 heavy plate, nm500 plate cutting, and SA573 Gr 70 carbon steel material nm400 price. Product specifications are: thickness 8-650mm, width 1500-4020mm, length 3000-18800mm. Products are widely used in the welding and manufacturing industries of containers, trains, oil tanks, and structural parts.

Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of SA573 Gr 70 carbon steel material metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.

Slow heating, preheating and other balanced heating methods can be used to reduce the heat treatment deformation of wear-resistant composite plate. Correct heat treatment process and reasonable tempering heat treatment process are also effective methods to reduce the deformation of wear-resistant composite plate. There are many reasons for the deformation of wear-resistant composite plate, SA573 Gr 70 carbon steel material. We only need to master the deformation law and analyze the reasons. The deformation of composite wear-resistant plate, SA573 Gr 70 carbon steel material can be alleviated and controlled.

What is the difference between Q345B steel and Q345A steel? SA573 Gr 70 carbon steel material, 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.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate SA573 Gr 70 carbon steel material EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
