ANSI Flanges refer to ASME/ANSI B16.5 -Flanges and Flanged Fittings. It is the ASME B16.5 – 1996 Pipe Flanges and Flange Fittings standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.

H10MnSi is recommended for JB/T4709, but the lower limit of H10MnSi allowable strength is 430 MPa, which does not match the parent material. I believe that the use of ER50-6 welding wire with ER70S-6 as the national standard can be guaranteed to be equivalent to the strength of the parent metal. The Si and Mn content can also ensure the deoxidation effect, making it difficult for the weld to produce air holes.
16Mn steel belongs to carbon-manganese steel, the carbon content is about 0.16%, and the yield point is equal to 343 MPa (strength level is 343 MPa level). The 16Mn steel has less alloy content and good weldability, and generally does not have to be preheated before welding. However, since 16Mn steels tend to harden slightly more than low carbon steels, preheating measures must be taken to prevent cold cracks at low temperatures (such as open-air operations in winter) or on large rigid, large-thickness structures.
16Mn steel welding is very good, the general use of TIG with J50 wire, hand arc welding with J506, J507 and other electrodes.
