Why Stainless Steel? Facts, Applications and Compositions by Eagle Stainless Tube

The many unique values provided by stainless steel make it a powerful candidate in materials selection. Engineers, specifiers and designers often underestimate or overlook these values because of what is viewed as the higher initial ost of stainless steel. However, over the total life of a project, stainless is often the best value option. Stainless steel is essentially a low carbon steel which contains chromium at 10% or more by weight. It is the addition of chromium that gives the steel its unique stainless, corrosion resisting properties. The chromium content of the steel allows the formation of a tough, adherent, invisible, corrosion-resisting chromium oxide film on the steel surface. If damaged mechanically or chemically, this film is self-healing, rovided that oxygen, even in very small amounts, is present. The corrosion resistance and other useful properties of the steel are enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen.

A Guided Tour of Wire Forms and Their Applications

From purely artistic and decorative to entirely functional, wire forms can come in a seemingly innumerable range of shapes and complexities. From simple wire ‘S’ hooks and peg board hooks to a complete rack of wire shelving or a rotating wire retail display, manufacturers that offer wire forming services are equipped to create many essential wire products for industrial, commercial and consumer use.

Laser Welding Creates Potential For Small Parts Applications

Laser welding is an effective method for joining small parts with tight tolerances. In the future, it will compete with traditional methods of welding or replace assembly/joining technologies benefiting industries that have never used laser welding before. Using light in the form of laser radiation as the energy source is a process used to achieve a balance between the process of thermal fusion and metallurgical effects. Functionally, the laser generates infrared or visible light (usually with the use of Nd-YAG lasers or frequency-doubled ‘green’ lasers for reflective metals) which is delivered through an optical fiber and focusing lens onto the workpiece. Welding is the process that occurs when laser radiation is absorbed by the workpiece and turned into heat raising the temperature in the localized area above the melting point…

Forging: An Ancient Art that Remains an Essential Metalworking Process

It’s not by magic that forging has survived and thrived as technology has advanced. The heart of forging has not changed since its origin in ancient Egypt. From the pre-industrial age on into today’s sophisticated forging facilities, the essence of forging remains the same: how it affects the structure of metals. The results are unequaled in any other form of metalworking. Discussing the different types of forging can get very complicated. Putting it more simply: heating the metal until it’s malleable breaks down the originally coarse grain structure, and then ‘kneading’ it between dies elongates the grains and they recrystallize in a new finer granular structure…

Why Use Extruded Aluminum?

by PSI Extrusions The aluminum extrusion process, which involves forcing hot aluminum through a precision die to create a length of constant cross-section, marries the inherent advantages of aluminum to the precision and high volume capacity of the extrusion process.

Investment Casting Soars Despite Misconceptions

Although one of the world’s oldest metal fabricating technologies, investment casting (sometimes known as ‘lost wax’ casting) has in recent years been subjected to a few misconceptions, ironically these fallacies have probably caused many who could have benefited most from this process to rule it out…
