Abrasive-resistant cast irons are the premier choice for industrial components facing extreme mechanical wear and erosion. To ensure consistent quality and performance, our Leesh Sand Casting processes strictly adhere to global standards such as ASTM A532, ISO 21988, and EN 12513. These standards categorize alloys based on chemical composition and hardness, providing a reliable framework for engineers to select materials that reduce maintenance costs and extend the service life of critical machinery.
