Depends on the maker. Some gun barrels are the finest quality type 4140 chrome moly or 416 stainless steel with button rifling. Hi-Point pistol frames are made from a high-impact polymer and barrels are from an alloy stainless steel.
Check out Azom.com. They have a lot of information on Stainless Steel Finishing. The European Stainless Steel Development Association has a guide to stainless steel finishes.
Stainless steel or WHICH metal? BTW, there are numerous grades of stainless steel. Some are stronger than others.
Yes, stainless steel is not magnetic in the same way as materials like iron, nickel, and cobalt. A regular magnet will not stick to stainless steel, although some types of stainless steel can become weakly magnetic through processes like cold-working.
Yes, stainless steel can be magnetized to some extent. The level of magnetic properties can vary depending on the specific grade of stainless steel and its composition. Generally, austenitic stainless steels (e.g. 304, 316) are not magnetic, while ferritic and martensitic stainless steels can be magnetized.
Some types of stainless steel are magnetic and some are not. Details are available via the stainless steel article on wikipedia.
Some of the older stainless steel microwaves can be a bit heavier than conventional microwave. However they have developed stainless steel microwaves that are made with a lighter stainless steel casing making them less heavy.
There are many online retailers that sell stainless steel plates. Some of these websites include Stainless Supply, MetalsDepot, Discount Steel, and Amazon.
In some cases yes. If the stainless steel was not passified (removing iron particles left on stainless steel by contact with tool steel dies) with nitric or sulfuric acid then yes.
Some of the most effective stainless steel cleaners include baking soda and vinegar as active ingredients. There are many name brand items available to clean stainless steel.
Yes, in common with all metals, stainless steel is a conductor, but it is not widely used as such. There are some, specialist, applications -such as stainless steel coatings to railway conductor rails.
Stainless steel won't tarnish or rust. It is more cost effective now to use a cheaper metal and coat it with stainless steel. Some hardware is brass coated with stainless steel.
