BS700MCK2

BS700MCK2 BS is one of a series of high-strength steel, Baosteel, engineering machinery series of high-strength, ultra high strength structural steel. Baosteel in 2000, first in China to the successful development of a new class of hot-rolled products, grades are mostly used at the beginning of BS, as the first generation of high-strength steel and BS700MC BS600MC have been widely used in engineering machinery, container and other industries.
