Stages of Rust

As a material that satisfies tough, industrial requirements and offers appealing aesthetics, metal is used for products everywhere. Metals boast resilience and strength in heavy-duty applications and hardscape supplies. In infrastructure, metal can be styled in versatile ways to blend in with both the traditional and contemporary. When high-quality new

Business Success: Saved through Innovation

Neither Brent nor Brad Done saw themselves becoming foundry men. Reliance Foundry had always been in their lives: the factory was a hot, smelly, dirty place that was equal parts proud family legacy and tough taskmaster. Their grandfather, Fred, had left the foundry to his children Brian and Barry. A

Maintaining your Stainless Steel

Stainless steel contains carbon, iron, and chromium. This chemistry, along with polishing and passivation steps in manufacturing, encourages the alloy to develop a chromium oxide layer. This layer is what gives the metal its prized rust resistance. Yet chromium oxide is itself a product of corrosion, a quick-forming “passive film”

Austenitic Stainless Steel

Stainless steel is called “stainless” because of its resistance to rust. Steel contains iron and carbon in certain percentages: adding the element chromium transforms it from steel to stainless steel. Chromium oxidizes much faster than the iron in the alloy. The resulting chromium oxide seals and protects the rest of

Metal Passivation

Many metals are vulnerable to corrosion when exposed to air and water. Corrosion can cause metal stress and part failure, so metallurgists seek ways to defeat it. One such method is metal passivation, a lesser-known method of corrosion-proofing a surface that uses a thin chemical layer as a seal. Passivation

What is Sand Casting?

Sand casting is a process that utilizes non-reusable sand molds to form metal castings. It is a common production method for metal components of all sizes, from a few ounces to several tons. Sand casting isn’t only versatile in the size of its products – it can also create exceptionally complex

Galvanization: Corrosion protection for ferrous metals

Ferrous metals, which contain iron, comprise 90% of the world’s metal manufacture. Iron is dense, strong when mixed with carbon, plentiful, and easy to refine, so is an excellent and dependable material for many industrial and structural applications. However, iron and many of its alloys—such as steel—are also highly prone


Ductile Iron

Ductile iron – also referred to as spheroidal or nodular iron – is actually a group of irons that exhibit high strength, flexibility, durability and elasticity due to their unique microstructure. Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted or deformed without fracturing.

Spectrometers for Elemental Testing and Analysis

Spectrochemical analysis is a type of chemical analysis used to determine the arrangement of atoms and electrons within molecules of chemical compounds. It observes the amount of energy absorbed during changes in motion or structure. The wavelength and intensity of electromagnet radiation is measured to produce quantifiable results that are
