Stress Concentration Factor
A stress concentration factor (Kt) is a dimensionless factor that is used to quantify how concentrated the stress is in a mechanical part. It is defined as the ratio of the highest stress in the part compared to a reference stress.A stress concentration, also known as a stress riser/raiser, is a...
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...
18/8 Stainless Steel
18/8 stainless steel is 304 grade stainless steel, which is the most widely used and flexible austenitic form of stainless steel. The numbers 18/8 represent the composition of this steel as 18% chromium and 8% nickel, making it very resistant to corrosion and oxidation.18/8 stainless steel is also...
4 Types of Concrete Floor Coatings (And What You Should Know About Each)

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 corrosion rate between mils per year and mm/y?
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...
