Product Description
Q390C Carbon Steel Seamless Steel Pipe
1: Q390C Steel Introduction
Q390C seamless steel pipe is a kind of low alloy high-strength structural steel with high strength, high toughness and fatigue resistance. Compared with traditional welded steel pipe, Q390C seamless steel pipe has higher load carrying capacity, longer service life and more reliable stability. In addition, Q390C seamless steel pipe has good corrosion resistance and high temperature resistance, which can maintain stable performance under harsh environmental conditions.
