ASTM A106 Gr.C Pipes

ASTM A106 steel seamless pressure pipe is called by another name ASME SA106 Grade C pipe. It is easily used for various engineering purposes or applications in industries whether small-sized or medium-sized or very large sized. The stock of the pipe is available in full range in Grade B and C, schedule 20 through XXH and SCH 10 through XXH,160, XH and STD. The wall thickness is to 2" wall into 4inch through 8inch OD, 3inch wall in 10inch through 18inch OD and 4inch wall in 20inch through 24inch OD.

ASME SA106C tube is a high-temperature, seamless carbon steel pipe used in applications that involve extreme heat and high pressure, such as in power plants, refineries, and chemical industries. The "C" grade indicates a higher carbon content, providing greater tensile strength and heat resistance compared to grades A and B. ASME SA106C tubes are commonly used in boiler systems, heat exchangers, and pressure vessels where durability and performance under stress are critical. They meet the strict standards set by the ASME (American Society of Mechanical Engineers).

SA106C is a seamless carbon steel tube for high temperature applications. Its chemical composition is similar to 20G, but C and Mn content is higher, so yield strength is about 12% higher, while plasticity and toughness are acceptable. It could reduce tube wall thickness by about 10% if used to make steam headers instead of 20G. This could save some material cost, reduce welding work and reduce stress on the steam header during boiler start-up.

Chemical composition (%) of ASTM A106

ASTM A 106 Grade B shall conform to a carbon equivalent (CE) of 0.50 maximum as determined by the following formula:
CE = %C + %Mn/6 + (%Cr + %Mo + %V)/5 + (%Ni + %Cu)/15 . A lower Carbon equivalent ration maximum may be agreed upon between the purchaser and the producer. S5.3 The Carbon equivalent ration shall be reported on the MILL test report.

Mechanical Properties of ASTM A106

Equivalent Designation

The chemical composition of the material does not correspond to Chinese materials, and the mechanical properties are similar to Chinese (GB/T699) 20# steel. ASTM is a set of American steel pipe standards. ASTM steel pipe A106 A corresponds to the Chinese standard is GB8163 and the material is 10# steel. A106 B corresponds to the Chinese standard. The GB8163 material is 20#, and A106 Gr.B does not correspond to Chinese materials.
