Development of boron-treated steel with microalloying technology for high strength bolts

$15.00

Much attention has been paid recently to the application of boron-treated steel for high strength bolt use, due to the elimination of the spheroidize annealing treatment in the bolt making process. This paper discusses microalloying technology, which makes it possible to produce such high strength bolts.
