DEVELOPMENT OF AUSTENITE STAINLESS STEEL PIPE AND ALLOY STEEL PIPE FOR POWER STATION BOILER IN JAPAN

To further increase the production efficiency of power stations in Japan, steam pressure requirement for power station boiler is being changed from extra-critical pressure to ultraextra-critical pressure,In this case,on the basis of the traditional manufacture technology for austenite stainless steel tubes,new austenite stainless steel has been developed by means of changed raw materials hence more suitable alloy tubes and alloy clad tubes made thereof.
