Shenyang University of Technology offers high-quality wear-resistant castings and stainless steel castings.

Industries such as mining, milling, earthmoving, and construction rely on heavy machinery that often operates under extreme conditions, leading to severe wear and tear. In many cases, wear-resistant cast components—used as machine parts—play a crucial role in extending the lifespan of equipment and minimizing downtime. For instance, these specialized castings supply critical wear parts for a wide range of mining machinery, including crushers, chute linings, mine car wheels, and pumps. Additionally, when heat or corrosion resistance is required, stainless steel-based wear parts offer an ideal solution.

To be classified as corrosion-resistant, stainless steel must contain at least 10.5% chromium, providing extra protection against corrosive environments where corrosion is a concern. The chromium content forms a protective oxide film, significantly enhancing the material's resistance to corrosion. Additionally, higher chromium levels improve oxidation resistance and boost fracture strength, especially at elevated temperatures. When designated as corrosion-resistant, stainless steel castings are engineered for use under conditions where operating temperatures remain below 1,200°F.

Heat-resistant steel castings are manufactured for use in environments where operating temperatures exceed 1,200°F. Compared to corrosion-resistant stainless steels, they have a higher carbon content—up to 0.75%. At extreme temperatures, this elevated carbon level enhances structural strength while reducing ductility.

Carbon content is the key difference between heat-resistant and corrosion-resistant stainless steel castings. To ensure that stainless steel castings perform well in corrosive environments, the carbon content typically needs to be kept below 0.20%.

Compared to carbon steel, machining stainless steel castings is more challenging, requiring slower cutting speeds and feed rates. Experienced manufacturers like Shenyang Gongda can deliver high-quality, custom-made wear-resistant castings—crafted from wear-resistant chromium white cast iron, steel, or stainless steel—to meet the demands of applications that require exceptional resistance to abrasion, corrosion, and heat.
