What is the difference between SA633 Gr C carbon steel plate sheet and 4140 metals

What are the characteristics of medium and thick plate, SA633 Gr C carbon steel plate sheet? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, SA633 Gr C carbon steel plate sheet is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

SA633 Gr C carbon steel plate sheet product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering

On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy SA633 Gr C carbon steel plate sheet steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of SA633 Gr C carbon steel plate sheet carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

Sulfur is a very harmful element in SA633 Gr C carbon steel plate sheet steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of SA633 Gr C carbon steel plate sheet steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
