Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most cost-effective alloying material for iron, but various other alloying elements are used such as manganese, chromium, vanadium, and tungsten. Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also less ductile.

Alloys with a higher carbon content are known as cast iron because of their lower melting point and castability. Steel is also distinguished from wrought iron, which can contain a small amount of carbon, but it is included in the form of slag inclusions. Two distinguishing factors are steel's increased rust resistance and better weldability.

Though steel had been produced by various inefficient methods long before the Renaissance, its use became more common after more efficient production methods were devised in the 17th century. With the invention of the Bessemer process in the mid-19th century, steel became an inexpensive mass-produced material. Further refinements in the process, such as basic oxygen steelmaking, further lowered the cost of production while increasing the quality of the metal. Today, steel is one of the most common materials in the world and is a major component in buildings, infrastructure, tools, ships, automobiles, machines,appliances, and weapons. Modern steel is generally identified by various grades of steel defined by various standards organizations.

What is the highest quality carbon steel or cold steel a katana can be?
Q. The highest quality i have seen is 9260 and i want to know if there is a higher quality steel.
Asked by Matt - Wed Feb 3 18:38:06 2010 - - 1 Answers - 0 Comments

A. Types of steel are one issue. But the quality of steel no matter what type is even more important. The only way to be sure that you are getting a good blade is to buy from someone that already has a reputation for producing great blades. Stop the questions about who thinks what type of steel is best and investigate the steel blades offered by companies like Bugei Trading company. they have good blades. Opinions vary, but Bugei has proven that they make good swords. That is all that is needed to be known. Any questions you have are best directed to them, not here.

How much do contractors charge to install steel roofing without removal of existing panels?
Q. I have picked some steel roofing out and I was wondering what price range I should expect to get. I have two very simple gable roofs one is 17sq. and the other one is 8 sq. I am planning on going over existing shingles, so no removal is needed. I am going to purchase all the materials at a local steel supplier.
Asked by PrachiDesai36 - Wed Jul 15 06:53:51 2009 - - 1 Answers - 0 Comments

A. If you are going over shingles, only one layer I assume, you still have to have a layer of wood nailers. Your deck needs to be a minimum of 5/8" where as most roofs only have a deck made of 1/2". Before you purchase the steel make sure your roof can accommodate the steel. Most can but it is a bit more complicated than just laying the sheets of steel down. I would suggest you contact 3 contractors and ask for estimates. The cost for labor should be about equal to that of an asphalt shingled roof. Where I live roofers charge by the square, between $35.00 and $45.00 per square plus materials. When you get a quote make sure they include all prep work etc.

How to clean stainless steel cookware factory polish residue?
