The metals/materials technology area has information on the most commonly used materials in metal fabrication ̶ carbon steels; stainless steels; high-strength, low-alloy steels (HSLAs); and the 6000 series aluminum ̶ and those that aren't as common, such as the red metals, refractory metals, titanium, and magnesium.

Maintaining a boiler system can be very expensive and require a lot of downtime for the equipment. The electric arc wire thermal spray process is one efficient way to create a protective overlay on boiler components and systems, helping to reduce replacement costs and outage times.

Free-machining steels shouldn’t be welded. If a fabricator has a job requiring a free-machining steel, engineers and fabricators should get together to determine the best action. Can welding be avoided by using fasteners? If not, which weldable materials exhibit acceptable machining characteristics, and do these materials meet design requirements?

At least a dozen chromium molybdenum (CrMo) steel combinations exist. One of the more recent alloys consists of chromium, molybdenum, vanadium, niobium (columbium), and nitrogen. Beginning sometime in the 1970s, this material became popular for use in high-temperature applications, such as gas and...

The goal when welding any material is to change its microstructure as little as possible and to preserve its mechanical and chemical properties. To achieve this you must be able to determine its weldability, control the heat input, and prevent rapid cooling.

Creating welding procedures for abrasive-resistant (AR) materials can be difficult because many of them do not conform to ASTM,ASME, or SAE standards for chemical or mechanical properties. However, these materials can be welded successfully.

Stainless steel is favored for many uses because it doesn’t rust and it’s easy to clean. However, for medical environments, copper is making inroads. Copper has been shown to kill six varieties of bacteria, and the EPA has registered more than 350 alloys to have antimicrobial properties.
