Wondering how 904L stainless steel round bar performs in real machining? In this video, we walk through a 28mm x 6000mm ASTM B649 bar — pickled, passivated and turned — and show how it feeds, cuts and threads on standard shop equipment. You'll see the finish, tolerance and straightness checks, plus practical tips for pump shafts, valve stems and acid-duty parts. Watch the demo and decide if 904L fits your next job.
