Metal Casting

Quenching makes steel hard but brittle. Tempering gives back the toughness. Together they produce the strongest practical condition steel can reach.

A weld can leave stress close to the yield strength locked inside the steel. PWHT is how fabricators remove it. Here is how it works and when it is required.

Twenty common casting defects in one place, grouped by what causes them, with what each one looks like and how foundries prevent it.

A casting fresh out of the mold is not ready for use. Fettling is the stage that turns it into a clean part ready for inspection and machining.

Building frames, car bodies, pipes, and nails are all made from low-carbon steel. Learn the composition, properties, and common grades of the most widely used steel in the world.

From engine blocks to manhole covers, cast iron is everywhere. Learn what cast iron is, its five main types, and why this centuries-old material is still used by modern industry.

Graphite shape decides whether cast iron is brittle or ductile. Learn how magnesium nodularization and inoculation turn ordinary iron into strong, impact-resistant ductile iron.

Among structural metals used in industry, magnesium holds the record as the lightest structural metal, about two-thirds the density of aluminum and only a quarter the density of steel. But this weight advantage comes with a production challenge most other metals do not share: molten magnesium is highly reactive and can ignite easily if not

Two cast parts made from the same mold and material can still show dimensional variation between units, because metal shrinkage during solidification is never perfectly uniform. Understanding casting dimensional tolerance, including the international standard that governs it, matters so designers and foundries share a common language when deciding how much precision is realistic to achieve,

Metal casting is one of the oldest and most vital manufacturing processes in the modern metal industry. We covered its stages, methods, and applications in metal casting basics. But behind a process that looks simple, castings are not always perfect. Casting defects are one of the most common problems faced by foundries and casting service
