There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products A573 Gr 70 carbon steel plate are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

According to the latest statistics of alacero, the consumption of finished steel A573 Gr 70 carbon steel plate products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A573 Gr 70 carbon steel plate nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A573 Gr 70 carbon steel plate steel, can be used as an alloying element of low alloy steel.
