Export great SA283 grade D carbon steel plate sheet to Canada

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of SA283 grade D carbon steel plate sheet, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.

Consumption of SA283 grade D carbon steel plate sheet, finished steel products in Latin America in 2019 was 64.2 million tons, down by 5% compared to 67.6 million tons in 2018. The decline in steel consumption in the region reflects the contraction of Latin American economies, particularly the three major economies: Mexico, Argentina and Brazil. These three countries together accounted for 87% of the reduced steel consumption in Latin America. However, our steel materials export volume to those countries did not decrease but show a increasing tendency last year.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the SA283 grade D carbon steel plate sheet and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.
