What are stainless steel reinforcing bars?
How are stainless steel reinforcing bars used?
Stainless steel reinforcing bars are not a homogenous category. There are different types of stainless steel bars depending on their microstructure, and they perform different functions. For instance, stainless steel rebars with higher level of chromium make it easier for the bar to not corrode (by forming an oxide film). On the other hand, stainless steel rebars with higher amount of nickel prove to be more ductile and easier to form. Similarly, elements like molybdenum and nitrogen also improve anti-corrosive properties.
Depending on the composition, stainless steel rebars are divided into different categories, and even within those categories they are divided into different grades. In general, however, stainless steel rebars are best used in places where the chance of easy replacement is low and/or corrosive tendencies are much higher.
1. Structures Close to Water
2. Structures Requiring High Ductile Strength
3. Unfamiliar/Unknown Environments
Stainless steel rebars are a very reliable choice for environments that are unfamiliar or unknown. This holds true for places where either inspection is not possible, or repairs are impossible and/or extremely expensive. In that case, it is safer to go with a stainless steel rebar which can promise longevity.
4. Places Requiring Low Magnetic Permeability
Another quality of stainless steel rebars is that they have low magnetic permeability. Unlike carbon steel rebars, which form their own magnetic field when subject to a field, stainless steel rebars form less fields. This makes them ideal for buildings that need less exposure to magnetic fields caused by iron. For example, hospitals (with MRI machines), toll booths (with tag systems), chemical plants, labs, nuclear plants, etc. all have steel.
Stainless steel rebars are helpful for the long life of any product of masonry. Bars from companies like Sunflag Steels are good because not only do they improve your construction process and outcome, but they are also reliable in their production.
