Internal Corrosion Sampling

Corrosion is a large and complex issue that is critical to the chemical process industries (CPI) as well as other industry sectors. Corrosion not only affects personal property like cars and homes but also affects commercial assets such as storage tanks, buildings, bridges, process equipment, and all types of piping. While corrosion is seen every [...]

C276 – When the going gets tough, the tough get going.

    The best heat exchangers have stood the test of time because of proper material planning.  In the heat exchanger industry, it is very important to minimize downtime and keep productivity at an optimal level.  Equipment is expected to perform well without excessive maintenance. When performing maintenance, there are numerous variables to be addressed.  [...]

What is the difference between hardness and toughness of a metal?

What is the difference between hardness and toughness of a metal?     The ASM Metals Handbook defines hardness as "Resistance of metal to plastic deformation, usually by indentation" (asmmaterials.info).  Therefore, when a compressive force is administered to a solid matter, we can measure how resistant it is to permanently changing shape. Why is this [...]

Fe2O3 Never Sleeps

Fe2O3 Never Sleeps Normally when someone hears about corrosion, they think it is a bad thing.  This is true in the case when steel “rusts” or creates an iron oxide on its surface.  This exposes the metal and subjects it to further corrosive attack.  The oxide is created when the iron in the alloy reacts with oxygen [...]

Effects of Alloying Elements in Nickel-Base Alloys

Effects of Alloying Elements in Nickel-Base Alloys The different elements that make up an alloy can drastically change the mechanical properties, corrosion resistance and the metal's microstructure. While chromium, nickel, molybdenum, iron may be the primary alloying elements, other elements like tungsten, carbon, aluminum, titanium, copper and sulfur can have significant effects as well. Understanding [...]

HEAT TREATING NICKEL ALLOYS

HEAT TREATING NICKEL ALLOYS Heat treatments are done to alloys and metals to change the properties to fit certain situations. Not all heat treatments are created equal. Because each metal has its own composition, heating and cooling operations performed on the metals to alter their properties happen at different temperatures.  Heat treating Fe based alloys [...]

DESIGNING AND PROTECTING PUMP SYSTEMS

  Many manufacturers offer pumps in standard materials that can be shipped quick at a minimal cost.  For some applications, this may be an attractive option.  For many applications in corrosive and/or erosive environments, a carefully planned design that considers the environment and requirements of the pump may reduce costs and fallout later. Factors to [...]

Alloy K500 Nickel Copper

  Nickel Copper alloys are known to have excellent corrosion resistance in certain media and good physical properties. When most think of Nickel Copper alloys they think “Monel5”, and when they think “Monel5” they are more than likely thinking of Alloy 400. But there is another Nickel Copper alloy, one that with a slightly different chemistry [...]

Boiler Tube Corrosion: How It Starts and How You Can Finish It!

Boiler system corrosion is caused by the interaction of water chemistry, the environment of the facility, operation procedures, and materials used in the construction of the system.  It costs the industry billions of dollars every year through failures and reduced performance.  Finding a solution to your problem requires discovery of the exact corrosion path then [...]

Corrosion in Public Aquariums

Common Problems Faced By Aquarium Owners and Operators   Public aquariums have a unique set of corrosion-related obstacles to overcome, which must be addressed to avoid early-onset corrosion problems and mitigate corrosion if it does occur. Material selection and maintenance strategies are critical in this endeavor; however, the importance of corrosion education for designers and [...]
