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.

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.

CPF has conducted experiments using finite element simulation of the hot stamping process. The process can help manufacturers predict such final part properties as thickness, temperature, and hardness distribution.

Challenges faced by stampers in the quest to produce a robust part are magnified when they form high strength steels. As materials increase in strength, the inherent tensile property variability increases. Using products from the family of grades known as the advanced high-strength steels (AHSS) complicate matters even more, since what is supplied from one mill may not be produced in the same way as that from another mill. Understanding how steel is made sets the stage for a more profitable relationship between the steel supplier and the steel consumer. The certified steel properties that come with the coil are useful, but more information about the sheet metal increases the likelihood of success.

Stampers use tests to evaluate tool materials and coatings for wear issues. The main tests are scratching tests, twist compression test, strip-reduction tests, and forming tests.
