Detailed Product Description

Brand and grade: 10#, 20#, 35#, 45#, Q345A, 27SiMn
Standard: GB/T 8162-1999, ASTM, DIN, JIS
Specification: Φ6 x 1 - Φ121 x 20

Seamless steel tube with ordinary construction use is made from the compounding of the high quality 10#, 20#, 35#, and 45# carbon steel as well as 16Mn, 5MnV low percentage alloy construction steel or 40Cr, 30CrMnSi, 45Mn2, and 40MnB alloy steel. The seamless steel tubes made from 10# and 20# are mainly applied to liquid transportation while those made from 45# and 40Cr are mainly used in producing mechanical spare parts such as parts of cars and tractors. It's very important to control and ensure the strength and rigidity in processing. Hot-rolled steel tube is in hot status when delivered whereas cold-rolled steel tube is opposite.
