ASTM A334 carbon steel pipe is a specially designed alloy steel pipe with added elements of manganese, molybdenum and silicon to significantly increase its strength and durability. This steel pipe also has excellent corrosion resistance, improves performance after heat treatment, and has excellent weldability.
According to different application requirements, ASTM A334 seamless carbon steel pipes are divided into multiple grades, including Grade 1, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8 and Grade 9. Each grade is designed to meet its specific pressure vessel requirements to meet different temperature ranges.
A334carbon steel round tube performs well in yield strength, its value is not less than 345N/mm^2. In terms of tensile properties, its elongation A reached 21%, showing good plasticity.
As a low temperature seamless steel pipe, A334low temp carbon steel pipe is normalized or normalized and tempered to optimize its performance. This kind of steel pipe is usually presented in this condition when delivered, ensuring its stability and reliability in low temperature environments.
