What is Carbon Steel A106 Grade B?
Steel with a carbon content of up to 2.1% by weight is called carbon steel. The American Iron and Steel Institute’s (AISI) definition of carbon steel reads as follows: steel when: no minimum content is stipulated or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, or zirconium to be added to achieve the desired binding effect; the minimum specified for copper does not exceed 0.40 percent or the maximum content stipulated for any element; When used in this way, the phrase “Carbon Steel A106 Grade B Pipes” can apply to any steel, including alloy steel, that is not stainless steel.
The term “ASTM 106 pipe” designates seamless carbon steel pipes that have been hot-rolled or cold-drawn (rolled). Seamless pipe used in high-temperature applications is covered by ASTM A106 standard specification. As a result, it can be used to transport fluids (such as water, oil, gas, or slurry), making it a crucial component of the mining industry.
Materials Grades ASTM A106
There are three categories of ASTM A106 materials based on the material’s chemical makeup (primarily Maximum Carbon percentage). These are:
Maximum 0.25% carbon content in A106 Grade A.
A106 Grade B, with no more than 0.30% carbon, and A106 Grade C, with no more than 0.35% carbon
The range of manganese’s percentage also changes slightly between grades in the chemical composition of the various classes, as was previously noted. The manganese content in A106 Grade A typically ranges from 0.27 to 0.93%, whereas it does the same for Grades B and C (0.29 to 1.06%). All three classes of Sa 106 gr B Chemical Composition have the same maximum proportion of additional elements like phosphorus, sulfur, silicon, copper, chromium, molybdenum, nickel, vanadium, etc. To be safe, ASTM A106 states that the cumulative percentage of all these other materials must not be greater than 1%.
