API 5L X60 (L415) PSL1 grade steel Supplier Australia

What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel .

Pakistan's iron and steel industry has suspended production and operation since the outbreak, the dawn reported on April 8. Last month, Prime Minister Imran announced a rescue package for the steel industry. Recently, Pakistan's steel industry called for the resumption of production as soon as possible. The Secretary General of the association of large steel producers in Pakistan said that steel is the pillar of Pakistan's construction industry, and Pakistan's economy cannot bear the consequences of the long-term closure of the steel industry. Any delay in the resumption of production will lead to the failure of the government's plan to revitalize the construction industry, which will have a negative impact on Pakistan's economy. It is hoped that the government will immediately resume API 5L X60 (L415) PSL1 grade steel production in the steel industry, especially those that are able to provide shelter for workers.
