material S690QL1 steel weld pipe

According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic material S690QL1 steel exports to 2.44 million tons, down 2.4 percent year on year, after January down 3 percent, the second consecutive month of decline. In the past three years, South Korea's steel exports have decreased year by year, from 31.67 million tons in 2017 to 30.44 million tons in 2018 and 30.38 million tons in 2019. Instead, South Korea's material S690QL1 steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials material S690QL1. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

Due to the excellent corrosion resistant properties, SA387 GRADE 91 Class 1 sheet is also an option for use in sour service environments. The material has good weldability and with its heat resistant qualities, the material is a highly versatile steel which can be used in numerous applications.

Yield strength, min, ksi [MPa]/(0.2% offset):60 [415]
Elongation in 2 in. [50mm], min, %:18

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. material S690QL1, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
