According to the market forecast released by Eurofer on August 5, the output of all 09CuPCrNi-A atmospheric corrosion resistant structural steel steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the 09CuPCrNi-A atmospheric corrosion resistant structural steel steel consumption intensity in the construction industry significantly less than other industries.
Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. 09CuPCrNi-A atmospheric corrosion resistant structural steel, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.
The requirements for toughness impact energy of 09CuPCrNi-A atmospheric corrosion resistant structural steel, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
