Tempering the important A572 Gr 42 CS steel carbon plate welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve A572 Gr 42 CS steel carbon plate strength, plasticity and toughness.
Since the beginning of this year, the global A572 Gr 42 CS steel carbon plate steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global A572 Gr 42 CS steel carbon plate steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
Structural steel for construction is used to build boilers, ships, bridges, workshops and other building materials. This kind of steel usually needs welding construction, so it is generally low carbon steel with carbon content less than 0.25%, which is mostly used in hot rolling or normalizing state. A572 Gr 42 CS steel carbon plate, Structural steel for machinery is used for manufacturing machines or mechanical parts. This kind of steel is often used after carburizing or quenching and tempering. The steel used for carburizing is low carbon steel with carbon content of 0.1% ~ 0.3%. Steel used for quenching and tempering refers to medium carbon steel with carbon content of 0.3% ~ 0.6%.
