Classification of stainless steel circle

production

Stainless steel bar can be made of structural austenitic, ferritic, martensitic-aging steel. Precision rolling to produce stainless steel bar 3 accuracy classes (normal, high, high degree of accuracy), as well as 2 classes on the curvature. For the food industry stainless steel needs to be certified, and the content in the composition of the Nickel should not exceed 1%. The most suitable for the food industry are steel grade AISI 304, AISI 316. Limit length of steel round — usually within 12 meters. The standard provides tolerances. So the circle length to 4 m may have a deviation of ±13 mm, length up to 6 m ±50 mm, length more than 6 meters — ±70mm.

According to the type of production range is divided into hot-rolled and calibrated. The calibrated range is cold-rolled and cold-drawn. On delivery, you should pay attention on absence of cracks or delamination. There may be minor scratches, pits, traces of broach. Usually comes random length with a diameter of 5 to 270 mm Range Ø 5 — 9 mm are supplied with bays, and a larger diameter — piles of straight line segments.
