Seamless STEEL PIPE, PE, ASTM A106 Gr.B, ASME B36.10M, SCH160 – what kind of stainless steel is this? What does Gr.B mean?
Gr.B carbon steel, non-stainless steel; similar to China’s 20 seamless steel tubes
Carbon steel – and yet they claim it’s stainless steel. . .
Seamless steel pipe, PE material, plain-end type; ASTM A106 Gr.B – Specification for seamless carbon steel pipes for high-temperature service; ASME B36.10M; SCH160 – Standard based on combinations of outer diameter and wall thickness
Seamless STEEL refers to seamless steel pipes. Stainless STEEL is a type of stainless steel pipe. A106 is a standard for carbon steel pipes used in high-temperature applications; Gr.B is one of the grades available, with Gr.A and Gr.C being other grades as well. The differences mainly lie in chemical composition and tensile properties. You can check this specification.
The entire description mentions carbon steel; how could stainless steel be mentioned? Gr. B refers to grade B, which is a grade for mechanical properties.
ASTM A106 Gr.B is a type of carbon steel pipe per ASTM standards, and it is similar to grade 20 steel. ASME B36.10M, SCH160 – ASME, a standard issued by the American Society of Mechanical Engineers; SCH160 is the pipe designation, indicating the pressure rating.
