Katalor is a well-knowAPI 5L PSL1 X80 line pipe supplier and exporter in China. We have lots of customers are from all over the world, they buy API 5L PSL1 X80 line pipe from Katalor every month. We can provide API 5L PSL1 X80 line pipe more information fro free.
The typical crabon content of API 5L PSL1 X80 line pipe is 0.04% to 0.08%, and some carbon conten is extremely low at 0.02%. Due to teh need of offshore and polar pipeline development, API 5L PSL1 X80 line pipe has a low carbon equivalent for the purpose of not preheating welding in harsh environments, post-weld heat treatment and ensuring low hardness of joints and avoiding sulfide stress corrosion cracking. The reduction of carbon content decreases the yield strength and is compensated by the use of other strengthening mechanisms. The most commonly used is the solid solution strengthening caused be the addition of Mn instead of C. Mn, which not only increases the strength but also increases the toughness of the steel and reduces the toughness and brittle transition temperature of the steel. As the increases of Mn content will accelerate teh central segregation of cotrolled steel , the range of Mn addition in steel is generally 1.1-2.0% according to different requirements of thick plate and strength.
