no he didnt
Most nails today are made of steel. Steel is mostly made out of iron but has some carbon and other materials added to enhance strength and resist rust.
Iron's hardness and ability to be forged into various shapes made it popular for use in weapons. It could be sharpened into a blade, making it useful for swords and spears, and its durability made it suitable for armor and shields.
Titanium and its alloys have very high strength-to-weight ratios. The densities of titanium-based alloys range between 0.160 lb/in3 (4.43 gm/cm3) and 0.175 lb/in3 (4.85 gm/cm3). Yield strengths range from 25,000 psi (172 MPa) for commercially pure Grade 1 to greater than 200,000 psi (1380 MPa) for heat-treated beta alloys.

High speed steel is made from different steel alloys. Depending on the application and budget the alloy is made from iron and different mixes of carbon, tungsten, cobalt, chromium, molybdenum, and vanadium.
Spaniards had steel swords, guns, cannons, and steel armor.
According to my calculations, Carbon Steel was used thousands of years ago, because, if carbon steel swords were invented thousands of years ago then- heres a question: if carbon steel swords was invented back then, then what made carbon steel swords? the same thing we use to make carbon steel, which is mainly carbon and iron. The carbon, when mixed with molten iron, in fixed proportions, steel of varying strengths are formed. Steel is strong since the carbon atoms enter the metallic lattice of iron the difference in size of the carbon and iron atoms restrict movement of the layers (atoms) hence when a force is applied, the steel resists. by 11SHIFT
Katanas are made from steel. Back in the 15th and 16th centuries, when the katana was widely in use, this was the best material. The steel matched with the craftsmanship of the sword-smiths made this weapon much deadlier than a normal sword of the era.
The short answer is no. For starters, if you are referrring to the weapon commonly referred to as the 'Ninja-to', it is a creation of pop-culture and has no precedent in the history of Shinobi. Ninja's did however use Katana's and Wakizashi, which are made from Carbon Steel(literally an alloy of Iron and Carbon, with no other elements). Tungsten is added to some modern swords, but Katana's are generally still made from Carbon Steel, though modern steel can be used, such as L-6.
Most tattoo needles are made of some grade of stainless steel. Surgical stainless steel is very common in tattooing needles.
The most common use for stainless steel bolts is to hold parts together. You may find stainless steel bolts in use on such common household features as plumbing, woodworking and more.
all sorts of armor! steel swords, cannons, and guns were some of the weapons though.
I live in a pod, and it's made outta steel, so YES! They use steel to make "you pods"
It depends on what you want to use it for. On the Moh's scale, steel is somewhere between 4 and 4.5, whereas iron is between 6 and 7. In swords, both iron and steel kinds have appeared, but steel is slightly better than iron due to its strength-to-weight ratio and its flexibility. Keep in mind, steel--unlike iron--is made of different metals to improve its strength. For piping, steel would be better (but not the first choice among other materials to use). Steel is also more resistant to rust, than iron, and the weldability of steel is better than iron.
they used swords made of rock and horns from animals
WHAT? OF COURSE NOT! You think we still use swords? Wow, we use guns!
yes, it is 20 ft and 5 tons made out of pure steel
