202 304 310 316 321 Stainless Steel Round Bar 2mm, 3mm, 6mm 8mm 12mm Metal Rod Stainless Steel Bars

202 stainless steel round bar: belongs to chromium-nickel-manganese austenitic stainless steel, and its performance is better than 201 stainless steel.Bar rolling is the easiest of all rolled products to achieve, and it can be done in many ways. Bars can be produced from the three-roller row type to the twisted double type, from various semi-continuous types to full-continuous types, but their output, dimensional accuracy, yield, and pass rate are quite different. The rigidity of the three-roll mill is low, and the fluctuation of heating temperature will inevitably lead to serious fluctuations in product size.

In addition, the slow speed of the horizontal row and the long rolling time will lead to an increase in the temperature difference between the head and tail of the rolled piece, which is prone to inconsistent dimensions and uneven performance. The yield is very low, the quality fluctuates greatly, and the high quality rate is extremely low. The full-continuous rolling mill generally adopts horizontal and vertical alternation, the rolling piece has no twist, less accidents, and high output, which can realize large-scale specialized production and structure performance control. The qualification rate has been greatly improved, especially the finished product rate has been improved, and the waste of returning to the furnace for steelmaking has been reduced. At present, new technologies such as stepping heating furnace, high-pressure water descaling, low-temperature rolling, and endless rolling are mostly used in bar rolling. Rough rolling and intermediate rolling are developing in the direction of adapting to large billets and improving rolling accuracy. Mainly to improve accuracy and speed.
