Q:Will this temperature affect the strength of steel component parts during the galvanizing process?
galvanize a Steel will lose some Small strength bu it will prolong the steel
Q:Shaft stiffness in steel irons???
If i understand you correctly, i think you misunderstand shafts. Steel shafts vs. graphite shafts these days is more of a competition of weights, not flexibility. Both steel and Graphite have different flex profiles available from Ladies (L) to super stiff (X). Graphite may feel a little more whippy than steel because of the lighter weight. Shafts will vary by company as well. Stiff from True temper may not be as stiff as one from Aldila, or vice verse. You can also make a shaft play stiffer or more flexible by where you cut the length. This is called tipping. Take more from the bottom and it will be stiffer, more from the grip end and it will play more flexible.
Q:Are steel doors insulated?
Steel doors are insulated,but will feel cold in the winter.Feel all around the door weather stripping area and the seal at the bottom of the door to see if air is getting in.
Q:Why not use stainless steel to make coins?
Stainless steel has been used by some countries to make coins, but it's not an ideal metal. When a coin is struck, a die comes down and strikes the blank with many tons of force (the blank is also sitting on top of another die--one has the image on the obverse (front) of the coin, while the other die has the image of the reverse of the coin). When the die strikes the blank, the force causes the metal in the blank to flow into the recesses of the die. The problem with stainless steel is that it doesn't want to flow into the die. To get an image, either the relief (how high the raised portion of the design will be) has to be very low, and the coin has to have a simple design, or they have to greatly increase the pressure of the strike. This slows the coining press down, and greatly shortens the life of the dies.
Q:stainless steel coating?
No, it's not possible. Quite apart from the chemistry which would prevent it occurring, the aluminium has a far greater rate of thermal expansion than stainless steel, so any coating wouldn't last.
Q:surgical steel or sterling silver belly button rings?
Implant grade surgical steel is best. Surgical steel is not cheap. You must be looking at something else. And sterling silver shouldn't really be worn in piercings anyway. Have you ever cared for actual silverware or platters or anything? Notice the brownish film it gets on it? That's from you really want that to happen inside your piercing? That's bad news man.
Q:Are solid steel or synthetic violin strings better?
Q:Why buy recycled steel?
Recycling old steel is very advantageous to manufacturers because it is always cheaper to use recycled metal scrap in Dubai than to expensively mine iron ore to gain it. Lucky Groups is one the recognized company to deal in recycled steel.
Q:will a stainless steel gun rust?
Q: will a stainless steel gun rust? A: Under certain conditions, it can rust. But stainless steel will last longer than blued steel will under such conditions. Also, some parts of a stainless steel revolver might not be stainless steel. The internal parts may be normal steel. Q: I just bought a used Taurus 85 stainless 38 spl revolver, it's about 25 years old but looks like new. This is my first stainless steel gun. I'm wondering if there's any special things I need to be aware of or cleaning methods? A: There are no special methods required. Stainless steel is fairly convenient easy to clean and maintain. Carbon-fouling can still build-up and metal discolorations may occur. These can be cleaned up with cleaning solvents and the use of a Scotch-brite cleaning pad or something similar. If it gets a scratch, the scratch can be polished away or left alone and the scratch can become a badge of honor or something. Q: I have a chrome bore AK, cleaning is always super easy, wondering of cleaning a SS revolver would be the same. A: Stainless steel is pretty tough on its own. Chrome-lining a stainless steel barrel wouldn't be considered cost effective in most circumstances. Cleaning the inside of a stainless steel barrel will be similar to cleaning a blued steel barrel that is not chrome-lined.
Q:What types of ammo can penetrate 1/2 inch steel plate ?
At what range and angle of impact? And is this mild steel plate or armor plate and if it is armor plate is it cemented, face-hardened or RHA? What Brinell hardness is it?
