Product Description

Carbon Steel Pipe Straight Seam Welded Pipe Spiral Steel Pipe



Q235 is a plain carbon structural steel that is used throughout China. It is also known as Q235A, Q235B, Q235C, and Q235D. Since it is mild steel, it is utilized in production without heat treatment. The Q designates the yield point, and the 235 indicates the yield strength.
Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications.
