ASTM A276 Round SS 321 DIN1.4541 Stainless Steel Round Bar OD110MM Heat Resistance
Stainless steel round bars are corrosion-resistant and rust-free, which makes them suitable for use in huge factories dealing with chemicals. Besides being resistant to heat and fire, stainless steel does not corrode, as it does not react to chemicals. The most common shapes are round bar (also called rod), rectangular bar (including square bar, the special case of equal sides), and hexagonal bar (usually called hex bar for short).
