Detailed description of mechanical properties of A573 Grade 70 high strength structural steel sheet

Wear resistant steel plate has high wear resistance:
The thickness of wear-resistant layer of wear-resistant steel plate is 3-12mm, the hardness of wear-resistant layer can reach HRC58-62, the wear resistance is 15-20 times of ordinary steel plate, 5-10 times of low-alloy steel plate, A573 Grade 70 high strength structural steel sheet, and 2-5 times of high chromium cast iron. The wear resistance is far higher than spray welding and thermal spraying.

Try to use A573 Grade 70 high strength structural steel sheet high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the A573 Grade 70 high strength structural steel sheet temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
