Q:Is it possible that stainless steel watches get rust. Any experience? Thanks.

Under certain conditions, even stainless steel will rust. They include: Exposure to some noble metals (copper/silver) in a corrosive atmosphere - and why stainless must be separated from silver or silver plate in a dishwasher. Stainless steel will pit if touching silver as many DW detergents are rich in chlorine. Under some conditions, and depending on your skin chemistry, if you wear a copper bracelet on the same arm as the watch, the surface of the watch will pit. If you commonly are exposed to some kinds of welding fluxes, if you are exposed to water with high salt concentration and you do not rinse off the watch after exposure, that can pit the surface. Stainless Steel is no more than corrosion-resistant, not corrosion-proof. Most of the time under most conditions, it is fine. But not all of the time under every condition. As it happens, what affects SS the most is any kind of electrolysis due to galvanic action involving halogen salts.

Q:Whats the difference in composition? When LTCS is used generally?Whats the temperature range, that these materials can be used? Is there any relation between Killed carbon steel, LTCS, stainless steel, carbon steel(normal)? How to categorise/classify these?Thankyou very much in advance..

When exposed to elevated temperatures, quenched and tempered steels are more susceptible than normalized steels to permanent reduction in strength. This is especially true when exposure temperature begins to approach tempering temperature used when the parts were produced. In addition to losing strength, tempered steels also may experience reduced impact toughness after being exposed to long-term elevated temperatures. General belief is that this is the reason for LCC's reduced maximum allowable temperature limit of 345°C / 650°F in B16.34.
