    Rust and corrosion are some of the biggest enemies of metals. These deficiencies can lower the strength of the part over time, and in some circumstances, become a safety issue. There is a difference between rust and corrosion, though. Rust is generally used to describe the oxidation of iron and iron-based alloys only. Usually, rust […]

    Thermal conductivity is a crucial quality of metals since it measures the amount and speed of heat the material can displace. This quality is especially important in high-temperature environments. Extremely high temperatures can change the properties of any metal, usually reducing the strength. Therefore, conducting the heat quicker can significantly reduce the stress on the […]

    Conventional steelmaking using electric-arc furnaces and decarburization is still very common. However, the internal structure of the cast ingots made with this process isn’t uniform, which negatively affects the qualities of the steel. Sure, a hot method can be used on the ingots to break up the segregated structure, but the structure still won’t be […]

    Pipe Schedule (SCH) is a standard that measures the nominal wall thickness of a pipe, given by the ANSI / ASME B36.10M standard for Stainless Steel Pipe dimensions, and API 5L standard for seamless and welded steel pipes. The pipe schedule number is non-dimensional and depends on the nominal pipe size, internal pipe working pressure, […]

    Applying heat to metals can make them easier to forge, machine, weld, and fabricate. However, this also brings some issues with it, metals expand when heated, which makes the whole fabrication process more demanding. Luckily, every alloy comes with a predetermined coefficient of thermal expansion. This coefficient shows how much a given alloy will expand […]
