What Are the Different Types of Steel?
According to the World Steel Association, there are over 3,500 different grades of steel, encompassing unique physical, chemical and environmental properties. In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determines the properties of each steel grade.
How to Price Scrap Metal
Article describing the steps necessary to price scrap metal properly, including tips on identification and market resources.
Types of Corrosion
Corrosion comes in many different forms. Ten common types of corrosion, including galvanic corrosion and flow assisted corrosion, are explained below.
Unique Properties: How Metal Conducts Electricity
Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons - electrons in the outer shell of an atom that are free to move about. It is these 'free electrons' that allow metals to conduct an electric current.
How to Identify and Prevent Corrosion
Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment.
Methods for Slowing and Stopping Corrosion
In virtually all situations, metal corrosion can be managed, slowed or even stopped by using the proper techniques. Corrosion prevention can take a number of forms depending on the circumstances of the metal being corroded. Corrosion prevention techniques can be generally classified into 6 groups:
What's Your Gold Really Worth?
With the price of gold soaring, many companies are looking for ways to get their hands on your unwanted gold. Most companies ask you to send your scrap gold pieces to them for analysis. Once they determine a value, you are then sent payment. But before you mail away your gold, you may want to determine for yourself what the melt value - the market value of the gold contained within the piece - should be.
