stainless-steel tool?

I think not. You can call it steel, but it is still very resistant to stains. And not just North Americans who expose this myth. The Germans call rostfrei, the French steel, and is free from oxide or oxygen is invulnerable. We all stainless steel to be just that -steel, but until now this is not the case. The water in the presence of oxygen, which acts as a catalyst has less effect on the alloys that constitute the several stainless steels that pure iron, but the effect is not zero. Tools and rust stains kitchen sink. When you buy a stainless steel pan realize they are trying to sell a stainless steel cleaner to go with it, and notes that the filter is really a fine abrasive compound. It is not intended that remove a few bits of fried egg.

The methods of manufacture can contribute to corrosion of the surface. When stainless steel is machined, the abrasion of the cutting tool can cause smallparticles of tool steel which is embedded in the surface of stainless steel. These oxide particles and form small holes. If water is present, septic can act as catalysts for galvanic corrosion cells, which removes material from the bottom and place it on the top, the widening and deepening of the boxes.

Lax quality control in small areas can result from impurities in the steel. These may be local areas of corrosion attack by selective catalytic. This is Especially if the source of recycled steel, which makes the composition is difficult to control accurately.

Stainless steels are dependent on the addition of chromium to provide oxidation resistance. For example, a 440C steel is often chosen for knife blades. With a chromium content of 17%, far higher than most steels, which resists oxidation so (but not completely). Many other elements are used to improve other qualities, but also with the addition of chromium to make it more resistant to oxidation of the steel, the final composition of any alloy is stilla compromise. Add an element too and can reduce the effects of the other.

Manufacturers of weapons to use against rust. Passivation, creating a surface layer or passive resistance is one of the best. Aluminum is a passivation example natural. When the pure aluminum surface exposed to air, there is an almost instantaneous creation of aluminum oxide that forms a thin hard skin, resistant to attack. Unfortunately, iron oxide (rust) does not work that way. However, the chromium-containing steels, manufacturers the use of acid baths to form a chromium oxide surface protective provides significant protection. Polishing removes surface micro-pitting can
be useful in areas not exposed to wear.

As mentioned above, you will not find a stainless steel in consumer products. If you want your article to be stainless steel, buy the best, keep it dry, keep it clean and keep it soft. And do not worry a bit of rust. Only nails.
