I have a bolt (13 kg) of stainless steel (1650 cm``). How much will this weight in sea water?
Thank you in advance!
Thank you in advance!
Does one mean 13 (13.000) kg, or perhaps 13,000 g? kg (g) is a unit of mass, N (Newton) or dyne (used in cgs system) is a measure of weight. Mass * acceleration of gravity would give weight (force) due to gravity.TorMcOst said:Thanks a lot for your respond Born2bwire!
This means that my calculation will become something like this:
Weight in Air: 13,000 kg
- Weight of fluid displaced (1650 cm3*1,025): 1,691 kg
= Weight in Sea Water: 11,309 kg
Correct?

However I got a little confused. By 13,000kg I meant 13 kg (in air). And my following answer was that this bolt would weight 11,3kg in water. Do you agree or disagree with this calculation?
As Born2bwire indicated, I was referring to the use of mass as weight. Being a physics forum, we wish to be accurate in such a matter.TorMcOst said:Thanks Astronuc!

Stainless steel is highly corrosion resistant in sea water due to its chromium content, which forms a protective oxide layer on the surface of the steel. This layer prevents further corrosion and makes stainless steel suitable for use in marine environments.
Yes, stainless steel can be used in sea water without any additional coatings or treatments. Its inherent corrosion resistance makes it a popular choice for marine applications.
Yes, there are different types of stainless steel that are specifically designed for use in marine environments. These include types 316 and 316L, which have higher levels of molybdenum and nickel for improved corrosion resistance.
Yes, the temperature of the sea water can affect the corrosion resistance of stainless steel. Higher temperatures, especially in the presence of chloride ions, can increase the rate of corrosion. Therefore, it is important to consider the temperature of the water when selecting the appropriate type of stainless steel for a marine application.
To maintain the corrosion resistance of stainless steel in sea water, regular cleaning and maintenance is recommended. This includes removing any marine deposits or biofilms that may form on the surface of the steel. Additionally, using higher grades of stainless steel and avoiding exposure to harsh chemicals can also help prolong the lifespan of the steel in sea water.
