The material of stainless steel round bar can be divided into 201, 304, 316, 304 and so on, and there are several kinds of stainless steel round bar production process? Here we'll look at several production processes of stainless steel round bar, stainless steel round bar can be divided into both cold and hot rolling processes,
1: cold drawn stainless steel round bar is made corresponding to the steel ingot plates after pass abrasive cold drawn out form of stainless steel round bar, generally for the following 12 mm stainless steel round bar, but if more than 12 mm of cold-drawn round bar should pass? This will need to use the black similar specifications of stainless steel after cold drawn out after annealing, pickling, generally don't operation, so the cost increase, unless the customer special requirement).
2: hot rolled stainless steel round bar is the ingot hot rolled stainless steel black after peeling polishing processing of stainless steel round bar, average for more than 12 mm bar is such operation,
So what is the difference between these two kinds of process? Stainless steel round bar surface tolerance after cold drawn unification, can guarantee in the plus or minus 0.05 mm, hardness is hard, because the stainless steel round bar after pass die extrusion between the inside of the molecular structure is more closely, so stainless steel round bar during processing is hard, but the surface of cold-drawn round bar is pitting. The surface of the stainless steel after hot rolling of round tolerance is not unified, can guarantee in the plus or minus 0.1 mm, soft hardness, because after hot rolling stainless steel round bar with peeling method directly to the surface treatment is good, that won't damage the inside of the stainless steel intermolecular structure, surface smooth and no pitting, easy processing, two bar process can be customized according to requirements.
