What material is ASTM A106

Posted:2022-02-15 10:12:27

A106 seamless steel pipe belongs to American standard steel pipe, A106 includes A106-A, A106-B. ASTM A106 seamless steel pipe includes two processes, cold drawn and hot rolled. In addition to the different production processes, the two are different in precision, surface quality, minimum size, mechanical properties, and organizational structure.

Mechanical Properties of ASTM A106

Seamless steel pipe standard Steel pipe grade Tensile strength (MPA) Yield strength (MPA)
ASTM A106 A ≥330 ≥205
B ≥415 ≥240
C ≥485 ≥275

Chemical Composition of ASTM A106

Steel pipe standard Steel pipe grade A106 seamless steel pipe chemical composition
C Si Mn P S Cr Mo Cu Ni V
ASTM A106 A ≤0.25 ≥0.10 0.27~0.93 ≤0.035 ≤0.035 ≤0.40 ≤0.15 ≤0.40 ≤0.40 ≤0.08
B ≤0.30 ≥0.10 0.29~1.06 ≤0.035 ≤0.035 ≤0.40 ≤0.15 ≤0.40 ≤0.40 ≤0.08
C ≤0.35 ≥0.10 0.29~1.06 ≤0.35 ≤0.35 ≤0.40 ≤0.15 ≤0.40 ≤0.40 ≤0.08

Note: ① Below the specified maximum carbon content, each time the carbon content decreases by 0.01%, the A106 seamless steel pipe is allowed to increase the manganese content by 0.06% above the specified maximum manganese content, but the maximum shall not exceed 1.35%;

②The sum of the five elements Cu, Ni, Cr, Mo, and V shall not exceed 1.00%

A106 seamless steel pipe is widely used in various industries such as petroleum, chemical industry, boiler, power station, shipbuilding, machinery manufacturing, automobile, aviation, aerospace, energy, geology, construction and military industry.
