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...
8 Things to Know and Understand About Iron Corrosion
Because oxide films produced by corrosion of iron are not self-healing, coatings and cathodic protection methods are generally used to protect ferrous surfaces.
Could Hydrogen Transport Mean Sustainability for the Pipeline Industry
The United States has a significant natural gas transportation and storage network. While companies are exploring transporting hydrogen using existing assets, careful consideration needs to be given to hydrogen's unique properties, and how they may impact pipeline assets.
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.

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...

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.,...

What are the different Xylan coatings and how do I decide which is best?
Xylan is an industrial dry film lubricant consisting primarily of one or more fluoropolymers including polytetrafluoroethylene (PTFE) (Figure 1), perfluoroalkoxy alkane (PFA) and fluorinated ethylene propylene (FEP). This coating is generally used to reduce friction, improve wear resistance and...
