Steel is a ferrous metal, aluminum is a non-ferrous metal
"A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines. Strictly speaking, the ruler is essentially a straightedge used to rule lines[citation needed], but typically the ruler also contains calibrated lines to measure distances"
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
the difference is the max load which the material will withstand until failure 52 stands more than 37
The term rule in this context is synonymous with ruler, a marked strip that can be used to measure length. A flexible steel rule is make of thin, flexible steel.
nothing because it is steel is steel
Steel is a ferrous metal, aluminum is a non-ferrous metal
A ruler made of stainless steel.

Another ruler
carbon .
they both rust and are good conducter of electricity
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
you use it in technology and car care you use the steel ruler for straight lines for wood and plastic and other things.
Not much, avaliability is the same also. Our default has changed to killed carbon steel.
the difference is the max load which the material will withstand until failure 52 stands more than 37
Accuracy has more to do with the measurement lines on the ruler than the material. In terms of making measurements , however, a steel ruler has several advantages to a plastic ruler of the same accuracy. For starters, steel rulers are often thinner than plastic rulers, positioning the measurement lines closer to the paper. As well as this, many steel rulers feature a backing made of a gripping material such as cork, which keeps the ruler firmly planted while drawing lines and making measurements. Lastly, the measurement lines on steel rulers are frequently embedded into the metal, whereas plastic rulers tend to have the lines painted on. After a while, these marks can be worn away, reducing the accuracy and readability of a plastic ruler.
