ASTM A106 is the black carbon steel pipe for high-temperature, high-pressure service of seamless pipeline in 3 grades A, B, and C of varying strength. ASTM/ASME A-106/ SA-106 grade smooth pipes is among our most extensively used grade of carbon steel and is easily available ex-stock for all standard densities as much as SCH160. NPS 1-1/2 and under may be either hot completed or cold drawn. NPS 2 and larger shall be hot finished unless otherwise specified. Surface area finish standards are described in the spec.
Grades A and B are accessible in the majority of sizes and schedule numbers, Grade B allows greater carbon and manganese contents than Grade A. The A106 Grade B supplied by ASTM Seamless Pipes has an optimal carbon material of 0.23%.
