What kind of steel bar is CRB600H steel bar?

CRB600H is a high-strength steel bar.

Similar to 550, this kind of steel bar uses hot-rolled low-carbon wire rod steel. Through high-speed and vigorous rolling, coupled with annealing treatment, the structural characteristics of the wire rod steel are changed. Specifically, the more nucleations are produced.

, the finer the grains, the yield strength and tensile strength of the steel bars are greatly improved.

Among them, 600 refers to the ultimate strength of the steel bar, which is 600Mpa. Because it is stronger than the previous steel bars, it is called high-strength steel bar.
