The blending of steel (making alloys) is a physical process. Though the structure of the steel changes, it is still chemically unaltered.

Is chromium is a steel gray solid a physical or chemical property?
chemical
Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is Burning wood is an example of physical change.?
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
Is the resistance to corrosion a chemical or physical property?
It is chemical. Stainless steel is an alloy of chromium, iron, and carbon. The carbon is what makes the iron harder, as iron is a very soft, malleable metal when pure. The chromium in the steel readily goes to the surface of the iron and oxidizes, forming a layer of chromium oxide. This is a tough layer on the surface of the steel, resisting scratches. It also protects the steel from rust. when the rust-resistant surface is scratched and iron is exposed to air, the chromium goes to the surface and readily oxidizes again. This protects the steel as long as there is chromium in the steel. When the chromium is gone then the steel will no longer be stainless and it will be able to rust. This lasts for about 20-40 years for the average stainless kitchen knife.
Is rusting steel wool a physical or chemical change?
Chemical. Rusting is known as "oxidization," a chemical reaction where oxygen reacts with iron.

What kind of property is stainless steel's ability to resist rust?
chemical property
Is color and hardness examples of chemical properties?
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Is magneting steel physical or chemical change?
Magnetizing a piece of steel, a needle for example, is a physical change, for it causes the spin of a group of electrons to be co-alignedrather then randomly oriented. The chemical composition of the steel is unchanged.
What property is Stainless steel's ability to rust?
Chemical- changed it into something new!
Is magnetizing steel a chemical or a physical?
physical, just the aligning of magnetic domains what were previously random in orientation.
Is rusting steel wool a physical or chemical change?
Chemical. Rusting is known as "oxidization," a chemical reaction where oxygen reacts with iron.
Is there a chemical or physical change when a bicycle rusts in the rain?
Rusting is a chemical change, as steel/iron turns into iron oxide.
