TP347H (1Cr19Ni11Nb) Nb are high-carbon Cr-Ni austenitic stainless steel, due to the stability of elements with Nb, the intercrystalline corrosion-resistant and multidrug-resistant acid Intergranular stress corrosion well in acid, alkali, salt and other corrosive media Bank and with its corrosion resistance of Ti is similar to the 18-8 austenitic stainless steel, it is widely used in boilers, power generation, petroleum, chemicals, synthetic fibers, food, paper and other industries. Ti than Nb difficult due to burning, the steel can be used as a welding and chrome-nickel austenitic stainless steel welding core. The steel is more than 316 grades of high-temperature strength and high temperature oxidation resistance and better performance, so they often use as a hot-strong steel.
