Q:ALLOY, GUNMENTAL OR STAINLESS STEEL?
Titanium alloy is. Its the hardest metal in the world and takes about 6 months to produce. I sell titanium juliets for 350.
Q:what coating can be used on steel so it wouldn't rust when exposed to sea water?
Galvinized means steel with a zinc coating. It is the best. For boats at port, and other fixed objects this can be supplimented with cathodic protection, an electrical method that substitutes corrosion of a sacrificial anode for the rusting of the steel. Epoxy and other coatings tend to be very temporary as they wear and scratch with use and lose all effectiveness if they cannot exclude seawater from contacting the bare metal. Zinc responds to abuse and can 'heal' over minor dings. The zinc is refreshed by periodic painting with a high zinc content paint or by electroplating.
Q:Is EN10025 S355JR weathering steel?
Is bether to use this one below! ASTM A588/A588M. Standard Specification for High-Strength Low-Alloy Structural Steel with 50 ksi [345 MPa] Minimum Yield Point , Weather Resistant
Q:What is better carbon steel or stainless steel for a knife?
Are you going to use it and take care of it? All butchers use the high carbon steel blades. If you want something to shine real pretty then go with the stainless.
Q:Probability of steel hardness?
Suppose that the hardness of steel is uniformly distributed, taking on values between 50 and 80 on the Rockwell B scale. That would be... f(x) = 1/(80 - 50), 50 ≤ x ≤ 80 . . . . . 0 elsewhere Consider this following problem.. Compute the probability that the hardness of a randomly selected steel specimen is less than 60. Here, we have... P(x 60) Oh! Know that the mean and the standard deviation of the uniform distribution function are... µ = (a + b)/2 σ = (a - b)²/12 You should get... µ = 65 σ = 75 Now... P(z (60 - 65)/75) = P(z -0.07) Hence, you should get around 0.462. Good luck!
Q:Steel Building Erectors.....!!?
Because if the beaming is screwed up, everything in the building is at risk. Also, if the erector runs late, everything else is delayed. An incompetent erector can actually cause damage to the beams [especially if inadequate bracing leads to collapse] and getting new ones can severely delay the project.
Q:Why can aluminum and steel casings not be used for reloading?
Some Blazer/CCI loaded ammo comes with aluminum casings, it is easy to tell because they have a very dull finish compared to the nickel. These cases are not safe to reload. There is also Wolf brand from Russia that has a steel casing, it looks laqured and it may or may not be able to be reloaded.
Q:where is cold formed steel framing used?
It will vary from location to location. A possible way of telling is how the material is joined. If the material is riveted together it is likely cold rolled. If the material is welded then its probably normalized steel (possibly annealed but less likely). Cold rolling increases the yield strength of the material so less of it is needed. However, it also make the material more brittle. Welding creates defects in the region surrounding the weld and these are more likely to grow and cause failure in a cold rolled steel than a normalised or annealed steels. In addition the heat from the welding will change the microstructure that was deliberately introduced by the cold rolling process resulting in a localised drop in yield strength. Normalised and annealed steels are more ductile and tougher than Cold rolled steel but they have a lower yield strength. Because they are tough and ductile they are less sensitive to crakcs and defects so welding won't lead to as big a reduction in strength. Another possible consideration is the environment they are used in. Steels exhibit a transition temperature (actually more like a range) where they go from behaving like a ductile material to a brittle material. A well known example of what this can cause are the Liberty ships in WW2 (Supply vessels from the US to the UK). These were made by welding together sheets of cold rolled steel to form one continuous Hull. Unfortuantely the transiton temperature of the steel taht was sued was around 4 degrees while the Baltic Ocean is about 0 degrees. As a result small cracks would grow and then when the reached a critical size they would tear through the ship at the speed of sound in the metal (1500m/s) and these massive cargo ships would literally snap like twigs. So, if the steel is being used somewhere really cold its unlikely to be Cold rolled too.
Q:Can I make a homemade blacksmith forge from an old stainless steel washing machine drum?

Q:Do steel guns burn when exposed to flames/ extreme heat?
Yes they melt and rather easily. Guns are made by melting steel and many police departments destroy confiscated guns by melting them.
