254SMO has good resistance to uniform corrosion. Especially in halide-containing acids, this steel is superior to ordinary stainless steel. Its C content is <0.03%, so it is called pure austenitic stainless steel (<0.01% is also called super austenitic stainless steel). Super stainless steel is a special stainless steel, which is first different from ordinary stainless steel in terms of chemical composition, and refers to a high-alloy stainless steel containing high nickel, high chromium and high molybdenum. Among them, the more famous is 254SMo containing 6% Mo, this kind of steel has very good local corrosion resistance,under the conditions of seawater, aeration, gaps, and low-speed erosion, it has good pitting resistance (PI≥40) and good stress corrosion resistance, and is a substitute material for Ni-based alloys and titanium alloys. Secondly, in terms of high temperature resistance or corrosion resistance, it has more excellent high temperature resistance or corrosion resistance, which is irreplaceable by 304 stainless steel. In addition, from the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenitic metallographic structure.Because this special stainless steel is a high-alloy material, it is quite complex in the manufacturing process, and generally people can only rely on traditional processes to manufacture this special stainless steel, such as pouring,forging,calendering and so on.Long Weld Neck Standard Connection Flanges refers to a flange with a tapered neck and butt welding with the cylinder or pipe. It is an integral flange.Due to the transition structure of the tapered neck and the butt welding connection, the strength and rigidity of the flange are enhanced, and the sealing performance is better than that of the flat welding flange. The disadvantage is that it needs to be manufactured with forgings, which consumes a lot of materials and has high manufacturing costs. It is suitable for occasions with high pressure and temperature settings or high sealing requirements.
