Product Description
Yile Machinery is a foundry specializing in the production of high-performance manganese steel castings. Also known as Hadfield steel, this material is the industry standard for components subjected to severe impact and abrasive wear.
The excavator link shown here is a testament to our ability to produce tough, durable castings that thrive in the harshest operating conditions.
High manganese steel (typically containing 12-14% Manganese, e.g., Mn13) possesses a unique and valuable property: it work-hardens.
Initial State: The steel is supplied in a tough, ductile, austenitic state.
Under Impact: When the surface is subjected to repeated impact or high-stress abrasion, it hardens dramatically, from ~200 BHN to over 500 BHN.
The Result: This creates a hard, wear-resistant outer layer while the inner core remains tough and ductile, preventing the part from fracturing under heavy shock loads. It literally gets stronger with use.
Key Benefits:
Extreme Wear Resistance: Outlasts standard carbon and alloy steels in high-impact applications.
Superior Toughness: Resists fracture and chipping from severe, repeated impacts.
Longer Service Life: Reduces downtime and replacement costs for critical machinery.
Producing high-quality manganese steel requires specialized foundry expertise.
Precise Alloying & Melting: We melt high-purity materials and precisely control the carbon and manganese content using a spectrometer to ensure optimal properties.
Expert Casting: We utilize robust molding techniques to produce sound, defect-free castings, whether the part is simple or complex.
Critical Heat Treatment: This is the most important step. After casting, the parts are heated to over 1000°C and then rapidly quenched in water. This "solution annealing" process creates the tough, austenitic microstructure necessary for work-hardening performance.
Finishing & Inspection: Castings are finished to your specifications and undergo rigorous quality checks, including dimensional verification and Non-Destructive Testing (NDT) upon request.
We pour various grades of manganese steel to suit different applications:
Standard Mn13 (ASTM A128 Grade A): The workhorse for general impact and wear.
High-Carbon Mn18: For even greater wear resistance.
Chrome-Alloyed Mn13Cr2: Enhanced strength and wear properties.
Our manganese steel castings are the preferred choice for wear parts in:
Mining & Aggregate: Jaw crusher plates, cone/gyratory crusher mantles and concaves, hammer mill hammers, shovel teeth, and track links.
Cement Industry: Mill liners and impact plates.
Shot Blasting Equipment: Blast blades, impellers, and liners.
Railways: Frogs, switches, and crossings.
