Normalizing heat treatment helps to remove impurities and improve ductility and toughness.
Chemical elements and effects on steel mechanical properties.
Hot cracking is one of the common casting defects in the production of steel castings, malleable iron castings and some light alloy castings.
Research shows that almost all defects of ductile iron are related to spheroidizing agent.
For metal castings, our more commonly used surface treatment methods are: mechanical polishing, chemical treatment, surface heat treatment, and sprayed surface.
The process of pouring cast steel is a very important step.
