Standing at a new historical starting point, we adapt to the requirements of supply side CCS A36 low alloy steel plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading CCS A36 low alloy steel plate steel materials supplier.
ASTM A285 is an ordinary carbon steel used for fusion welding of pressure vessel equipment, such as CCS A36 low alloy steel plate boilers, storage tanks, heat exchangers, etc. The tensile strength of the three steel grades (Grade A, Grade B, and Grade C) ranges from 310-515Mpa, and ASTM A285 steel plates are usually delivered in the rolled state. According to user requirements, CCS A36 low alloy steel plate is produced by processes such as compaction, semi-compaction, edge sealing and boiling water.
Ordinary medium and thick steel plate CCS A36 low alloy steel plate is a kind of deoxidized steel. The oxygen content of the steel liquid is relatively high, and a lot of gas will be produced during the production process to make the steel liquid boil, so it is also called boiling steel. Advantages: this kind of steel plate has smooth surface, good quality and easy processing. Because this kind of steel plate has no concentrated shrinkage cavity, the amount of deoxidizer is very small and the price is lower than other steel plates.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the CCS A36 low alloy steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This CCS A36 low alloy steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
Chemical composition differences between the CCS A36 low alloy steel plate, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
