Forged alloy steel round bar is one type of our products. We (HHF) own forging workshop, rough machining workshops, heat treatment workshop amd final machining workshops . And we also have a National Level II lab. Accordingly, the whole progress and quality can be controlled very well.
Our forged alloy steel round bars are made of 4145H, 4140, 4340 etc materials.
Manufacturing time( quick) is also our big advantage for steel round bar.
Our national level II lab controls the quality.
