Stainless Steel Pipe Flange Sus304 316 SS Flange 321 347 Customized

304 stainless steel is the most common steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties.304L, as a low-carbon 304 steel, has similar corrosion resistance to 304 steel in general condition, but it has excellent resistance to grain boundary corrosion after welding or stress relief; it can also maintain good corrosion resistance without heat treatment, and the service temperature is - 196 ℃ ~ 800 ℃.
316 stainless steel has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength due to the addition of Mo. It can be used under severe conditions.316L as a low carbon series of 316 steel, it has the same characteristics as 316 steel, and has excellent resistance to grain boundary corrosion.
321 stainless steel is an austenitic stainless steel of Ni-Cr-Mo type. Its performance is very similar to 304. However, due to the addition of Ti, it has better resistance to grain boundary corrosion and high temperature strength.
347 stainless steel tube has the characteristics of high strength and no reduction in plasticity because of the increase in intergranular corrosion resistance due to the Nb content, which reduces the thickness of the material. TP347H has good resistance to intergranular corrosion and intergranular stress corrosion due to its stable element Nb.
