Tensile Strength
Tensile strength is the ability of a material to withstand a pulling (tensile) force and refers to the breaking strength of a material when applying a force capable of breaking many strands of the material simultaneously, at a constant rate of extension/load. It is customarily measured in units of...
Frictional Force
Frictional force is the opposing force that is created between two surfaces that try to move in the same direction or that try to move in opposite directions. The main purpose of a frictional force is to create resistance to the motion of one surface over the other surface. The frictional force...
Ferrous Metal
A ferrous metal is any metal that is primarily composed of iron and has magnetic properties. A ferrous metal is known for its hardness, durability and tensile strength. Some common ferrous metals include:Alloy steelCarbon steelCast ironWrought ironFerrous metals are known and used for their...
An Introduction to Stainless Steels
When selecting the grade of stainless steels available, it is important to consider how components will be fabricated and joined together and the specific environment to which it will be exposed, in addition to the considerations common to other alloys such as mechanical requirements and cost.

5 Ways to Measure the Hardness of Materials
Hardness is not defined by any one universal scale or unit of measure. Several tests are available to assess this property, with each having its own unique set of advantages and disadvantages.

Why is Stainless Steel Corrosion Resistant?
Corrosion resistance is greatest when the steel is boldly exposed and the surface is maintained free of deposits.

Does zinc rust?
The short to the question is, yes. Zinc does rust. Like all metals, zinc corrodes when exposed to air and moisture. However, this element does not rust like most other metals.Iron, for example, reacts with water and oxygen in the atmosphere to form hydrated iron (III) oxide on the surface of the...

Where can I find a coating that is chloride and sulfur corrosion-resistant?
Thank you very much for your inquiry. We get questions like this all the time, and they are far more complex than most people realize.First, to be clear, we are consultants who do this for a living. But, we are unusual even in that regard, as we are vendor neutral. That is, all we do every day, in...

How can I convert the corrosion rate between the mils per year and the metric equivalent millimeter per year (mm/y), and why does this matter?
A corrosion rate conversion is a technique to change the measurement units of a given corrosion rate to another unit for comparison purposes or a specific engineering application. When converting a corrosion rate between these units you must keep in mind that a mil is a thousandth of an inch (i.e.,...
