Stainless Steel is used because it has an higher corrosion resistance over normal steel.
No, an oven being stainless steel does not make it work better than a non stainless steel version.
Lead is much heavier than stainless steel.
It is far less likely to stain than normal steel, but it can in certain conditions.
Stainless steel or WHICH metal? BTW, there are numerous grades of stainless steel. Some are stronger than others.
No, 316 stainless steel is not harder than A106 carbon steel. In fact, carbon steel is generally harder than stainless steel due to its higher carbon content. Stainless steel is known for its corrosion resistance and durability, while carbon steel is valued for its strength and hardness.
No, stainless steel never corrodes.
Stainless steel is a steel-chromium alloy that is more resistant to corrosion than carbon-steel or other steel alloys. As with all steel, it strength depends on its grade; but overall the strength difference between carbon steel and stainless steel is negligible.
no, steel is heavier
"Stainless" means that it doesn't rust.
Many stainless steels are stronger than mild steel. Stainless steel is also corrosion resistant to many different environments where mild steel is not.
Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
Easy. A rod or electrode used in welding stainless steel. Or to "clad" a surface with stainless steel. (Nothing more than laying down a layer or layers of stainless.) MIG wire also comes in stainless steel. Their are different types of stainless steel and rods/wire/electrodes to use on them.
