How to prevent cracks in high manganese steel castings?
For each major link in the production of high manganese steel castings, measures should be taken from the following aspects to prevent the occurrence of cracks. Structural design of castings Structural problems such as too large a difference in wall thickness of castings, improper wall thickness transition, and too small fillet transition of castings […]
How to perform heat treatment of high manganese steel?
The purpose of solution heat treatment of wear-resistant high manganese steel castings: Eliminate the carbides within the grains and grain boundaries in the as-cast structure to obtain a single-phase austenite structure, improve the strength and toughness of high manganese steel, and expand its application scope. To eliminate the carbides in its as-cast structure, the steel […]
How Does Investment Casting Work?
Investment casting works by pre-applying coatings to the pattern—before investment casting mold creation, or to the mold—once it is fired. This serves several important purposes. Refractory coatings are applied to the interior surface of the mold to provide a barrier between the mold material and the molten metal. This reduces oxidation, contamination, and marking. An […]
How Does Investment Casting Differ From Other Types of Casting?
All casting methods use a heat-resistant cavity that is the shape of the desired part as a volume to be filled with liquid metal, which is removed once solidified. The means by which the cavity is formed is the primary differentiator of casting methodologies. Die casting uses a two-part (or more) hardened-steel cavity tool that […]
Application of intercooler in automobile
An intercooler is a heat exchanger used in vehicles, particularly in turbocharged or supercharged engines, to cool the compressed air before it enters the engine’s combustion chamber. Here’s how it works in an automotive application: Turbocharger/Supercharger Operation: In turbocharged or supercharged engines, air is compressed before entering the combustion chamber. This compression generates heat […]
What Is Investment Casting?
What Is Investment Casting? Investment casting is a precision casting process used to create complex and intricate metal parts with high dimensional accuracy and fine surface finishes. This casting method is ideally suited to producing relatively high-quality components with intricate details, delicate features, and tight tolerances. Investment casting is commonly used in industries such as: […]
Quenched and tempered steel
01 Manganese steel Representative of steel 40Mn2, 50Mn2. Overheating sensitivity, high temperature tempering brittleness, water quenching is easy to crack, hardenability is higher than carbon steel. 02 Silicon manganese steel Representative steel grades 35SiMn and 42SiMn. High fatigue strength, decarburization and overheating sensitivity, and temper brittleness. It is used to manufacture gears, shafts, rotating […]
Heat treatment of steel castings
Steel castings should be used after heat treatment. Because there are casting defects such as pores, cracks, shrinkage cavities, shrinkage porosity, coarse grains, uneven structure, and residual internal stress inside the cast steel castings, the strength, especially the plasticity and toughness of the steel castings are greatly reduced. To refine the grains, uniformize the […]
What Are the Advantages of Sand Casting?
What Are the Advantages of Sand Casting? Sand casting, despite being an ancient process, offers advantages that render it highly relevant in high-technology production. Such benefits are: Low cost. Simple tooling. Easy scale-up, but great for prototyping. Fast turnaround. Few design limitations, shape complexity. Extremely wide range of materials with few/no process changes. A wide […]
Casting process characteristics of cast steel
The mechanical properties of cast steel are higher than those of cast iron, but their casting properties are worse than those of cast iron. Because the melting point of cast steel is high, the molten steel is easy to oxidize, has poor fluidity, and shrinks greatly. Its volume shrinkage is 10 to 14%, and its […]
