Alloys 347 and 347H are high carbon niobium stabilized austenitic stainless steels with added niobium. The addition of element Nb makes TP347H have good intergranular corrosion performance, especially for corrosive media such as acids, alkalis, and salts. It is widely used in heat exchangers, superheater tubes, reheater tubes, and steam tubes in industries such as power generation, petroleum, chemical industry, synthetic fiber, food, and papermaking. The element Nb is less susceptible to burning than Ti, so it can be used as a welding rod for Cr-Ni austenitic stainless steel. Similar to Ti-containing 18-8 austenitic stainless steel, grade 347H has higher high-temperature strength and better oxidation resistance than 316 stainless steel.
316 stainless steel is an austenitic stainless steel. The addition of Mo element greatly improves the corrosion resistance and high temperature strength. It can withstand high temperatures of 1200-1300 degrees and can be used under harsh conditions.
The tensile strength (Mpa) of 316 stainless steel is 520MIN, the yield strength (Mpa) is 205MIN, and the elongation (%) is 30MIN. Its main uses include heat exchangers for pulp and papermaking equipment, dyeing equipment, pipes, and exterior materials for buildings in coastal areas.
