Q:Why do we galvanise steel?
Keeps it from rusting. Zinc doesn't rust like steel does.
Q:Questions about Steel. Please Help?
It is usually a grey color, more silver when freshly scratched. Every one of the other questions can range based on the quality of the steel and other variables such as thickness. That's more than likely the reason you couldn't find any info on it. Its hardness is based on quality, for example regular steel is softer than Mild steel. It can be a thin sheet or a thick plate (which could then be changed to a tube Circle or square) etc
Q:material of guns before steel?
The most common was bronze, which was the strongest material that could be cast, at least until the industrial revolution. Until that time, furnaces which could reach temperatures hot enough to melt steel did not exist. The only way to work with steel would have been forging, which means hammering it into shape while red-rot. Obviously, this is not a very practical method for making large thick-walled cannons (though it was done on occasion. Small arms such as pistols and muskets could be easily made of steel by hand forging.) The most practical way to make cannons was pouring molten bronze which melts at significantly lower temperature than steel. Cast iron was also used. Note that Cast Iron contains 3%-7% carbon, compared to steel which only contains between 2% to 0.2% carbon. Due to the excessive carbon content of cast iron, it's melting point is about 500 degrees lower than steel enabling it to be melted with pre-industrial furnaces. Unfortunately, cast iron is also brittle, unlike steel or bronze. This means that a defective or cracked casting could easily explode, sending iron shrapnel everywhere. (Also, maiming and killing the gun crew, an experienced gun crew was as valuable as the cannon itself!) For this reason. Cast iron cannon were usually considered a cheap, risky alternative to expensive but durable bronze.
Q:types of stainless steel?
Types of stainless steel There are over 150 grades of stainless steel, of which fifteen are most common. The AISI (American Iron and Steel Institute) defines the following grades among others: - 200 Series—austenitic iron-chromium-nickel-manganese alloys - 300 Series—austenitic iron-chromium-nickel alloys Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Type 303—free machining version of 304 via addition of sulfur Type 304—the most common; the classic 18/8 stainless steel Type 316—Alloy addition of molybdenum to prevent specific forms of corrosion - 400 Series—ferritic and martensitic alloys.
Q:Is clorox safe to clean stainless steel?
I think not. I owned stainless steel sinks before that were they were in style. I used Clorox and more on them and they always turned out great. found wiping them out with a paper towel made them shine.
Q:what are the differences between chrome and stainless steel?
I know nothing of aftermarket headers so can't help you there, but - chrome is a coating on metal. Stainless Steel is a type of metal.
Q:Aluminum and Steel brittle or ductile based on these results?
Only steel(of this pair)might be liable to brittle fracture,which would be implied by almost zero elongation or reduction in area at fracture.On this basis the steel has not failed by brittle fracture.I would expect much more elongation in pure aluminium than your sample shows so I presume it to be brittle unless it is an alloy rather than commercially pure aluminium.However brittle fracture in metals is a particular phenomenon to be determined by impact tests and examination of fracture surfaces and is particularly relevant to metals with the body centred crystal structure.
Q:Steel Barns..........?
Barns can be constructed out of a number of materials be it steel, block or wood. Among all the available materials, steel offers the best in terms of strength, durability and pricing. Constructing a barn using wood can be a costly task because of the high price of wood. On the other hand, constructing a barn using block consumes more time and involves a much more professional approach thereby increasing the labor costs. Considering all these factors, it is always recommended to go for steel barns due to their durability, robustness and longer life span.
Q:i need help about stainless steel?
Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
