At the same time of doing well in A573 grade 65 CS steel carbon plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A573 grade 65 CS steel carbon plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Difference between Q235 steel and Q345 steel: First, The lower limit of yield strength of Q235 steel is 235MPa, and that of Q345 steel is 345MPa. Second, Q235 steel is common carbon steel, Q345 steel is low alloy steel. They have different alloy contents. Besides, Q235 steel is for general strength application, Q345 steel is for higher strength application. A573 grade 65 CS steel carbon plate, Q345 steel price is higher than Q235 steel price. But Q345 steel can save materials for sake of high strength.
Bridge steel plate is specially used for erecting railway or highway bridges. A573 grade 65 CS steel carbon plate, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.
Laser cutting, it is a specific way of cutting A573 grade 65 CS steel carbon plate steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting A573 grade 65 CS steel carbon plate speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
T11 steel is a steel grade produced according to American Standard ASTM A213. T11 steel is used for boiler, superheater and heat exchanger tubes with minimum wall thickness. Chemical composition of ASTM A213 T11 steel: C 0.05-0.15, Si 0.50-1.00, Mn 0.30-0.60, P, S ≤ 0.025, Cr 1.00-1.50, Mo 0.44-0.65. Mechanical properties of ASTM A213 T11 steel: tensile strength ≥ 415 Mpa, yield strength ≥ 170 Mpa, elongation ≥ 30%. The main ASTM A213 steel pipe grades are A213 T11, A213 T12, A213 T22, A573 grade 65 CS steel carbon plate, etc.
