What Is Jis B2220?


Because the inner diameter of the jis b2220 is manufactured slightly bigger in comparison to the pipe's outside diameter, it is easier to recognize this flange. Medium grade jis carbon steel flange generally has good resistance to corrosion and moderate tensile strength. Mild carbon grade steel jis b2220 blind flange is easily machined. Therefore, our buyers prefer using these JIS B2220 Flanges for structural construction work.

Apart from carbon steel, stainless steel grades such as 304 or 316 are used in the manufacture of these JIS B2220 Flanges. The austenitic nature of alloy grades 316 & 304 prove to be beneficial for the jis 16k weld neck flange. Grade 304 stainless steel is considered to be rather versatile and is the most commonly used alloy used in the manufacture of JIS Flanges Dimensions. Although, in terms of its mechanical and corrosion resistance properties, it lacks the characteristics of stainless steel grade 316. For e.g. – alloy 316 or as also referred to as marine grade jis b2220 16k flange stainless steel flange not only has good resistance to corrosion, but also has good resistance to pitting and chlorine containing compounds.
