【Abstract】 ST5”BZ]This paper tries to find out the reasonable process of heat treatment for PC(prestressed concrete)steel bar,including the temperature of quenching and tempering and the cooling way after tempering,by means of heat-treatment experiments of steel grade.These steel bars with a reasonable range of chemical composition and heat-treatment process have the same mechanical properties of those of Japan.All of thess provide basis for producing domestic PC steel bar products.更多还原
