Understanding The Brinell Hardness Scale Developed in 1900 by Swedish engineer Johan August Brinell, the Brinell hardness scale is used to test the hardness of metal. The Brinell test is one of the main three tests of hardness in the steel industry, along with the Vickers and the Rockwell hardness tests. The method involves indenting a test material with a hardened steel or carbide ball that is 10 mm in diameter with a load of 3000......

Case Hardening Of Steel Gives It The Edge In Some Situations Case hardening is a processing method used to harden low-carbon steel. Carbon and alloy steels are most often case hardened. You will find this true in applications such as knife blades and other similar uses.In this process, the surface of the steel that is treated has carbon added to it. The result is an outer layer of steel that is hard, with an inside core that remains softer and pliable.Case...... Similar Editorial : by sfrom. | Source : Science Project Ideas
Technologies In Rolling Sheet Metal To Ensure Quality Control Steel in its basic slab form requires rolling processes to enable its formation into sheet metal form. Once in this form it can receive more rolling to alter its thickness further.First, as an overview, there are two types of rolling performed on basic steel. One is flat rolling the other is profile rolling. These two types produce final products that differ greatly from each other. In both......

Managers In The Field Must Understand Material Grading Systems Managers in productions processes must know and understand the system by which raw materials they use are graded and the codes that indicate those grades. This is important from the front office all the way down to the shop floor. Engineering and project managers need to select the correct material not only for their project, but that is feasible to use within the configuration of their existing......

Sheet Metal Fabrication Machines | Industrial Machines Manufacturers, which produce various steel products, require punching of sheet metal to meet design requirements. Technology has entered the scene of this once manually operated process. This not only increases the speed of production but it gives a new meaning to the term "accuracy" in the positioning of the specific operations. This has been accomplished with the introduction of CNC or computer...... Similar Editorial : by News Canada. | Source : Computer Tower Cases
Investors Watch: Trends And Outlooks For The 2008 Steel Market Industry experts have begun 2008 with announcements that steel-making costs are likely to increase this year. This rise in costs is due to input costs in the production process. The production costs mentioned are prices for scrap, electricity, and coal; all items used in various steel manufacturing. As well, iron ore, the raw material of steel may see an increase in its prices according to...... Similar Editorial : by Uwe Falkenberg. | Source : Offshore Investment Funds
Cutting Sheet And Plate Metals Technological advances in the field of manufacturing are what companies use to gain and maintain a cutting edge over their competition. Thirty years ago no one would believe the technologies of James Bond and Star Wars would find their way to the metal fabricator's shop floor; but they have. Two innovative alternatives to burning or oxidizing sheet and plate steel are:* Laser Cutting of steel*...... Similar Editorial : by necess. | Source : Biofuel Technology
Reasons Behind Using Assist Gases In Laser Cutting Processes Ever wonder how they get those holes in that stainless steel sink so that the fixtures and drain can be installed? Maybe you've seen the Majestic Roof Garden Hotel in Adelaide and wondered how the precise steel facade was created. Modern laser cutting has provided the means to creating such high quality cutting of stainless steel.Laser cutting is a technique that allows faster and higher quality......

Iron And Carbon Make Wonderful Things When Allied With An Alloy We've grown up hearing about stainless steel our whole lives. But how many people actually know what it really is? Let's take a look at the process of making steel stainless and some of its general applications.English metallurgist Harry Brearley invented stainless steel in 1912 while he was researching alloys to protect cannons from erosion. The first commercial production of stainless steel...... Similar Editorial : by teahupoo. | Source : Pharmaceutical Biotechnology
