X120Mn12 High Manganese Steel Plate
X120Mn12, also known as Hadfield steel, is a high-manganese wear-resistant steel plate engineered for superior performance in abrasion, impact, and stress-heavy environments. Manufactured in China and supplied worldwide, this premium-grade alloy offers outstanding toughness and longevity, making it the preferred choice for industries such as mining, construction, and industrial machinery manufacturing.
- Description
Key Features of X120Mn12 Steel Plate:
-
Exceptional Wear & Impact Resistance
Work-hardens on impact from HB170 up to HB550, delivering unmatched durability in high-friction environments. -
High Strength with Superior Toughness
With tensile strength between 880–1130 MPa and yield strength ≥ 410 MPa, it resists deformation even under extreme loads. -
Excellent Work Hardening Properties
The steel’s unique composition of 11–14% manganese and high carbon enables surface hardening under continuous impact, while maintaining core ductility. -
Superior Thermal Stability
Retains its mechanical properties under high temperatures, making it ideal for harsh environments like quarries, blast machines, and smelting operations. -
Easy Fabrication & Processing
Can be plasma cut, laser profiled, welded, bent, and drilled with ease. Its low-alloy structure minimizes the risk of cold cracking or thermal distortion during fabrication.
Applications of X120Mn12 Wear Plate:
-
Mining equipment: jaw crushers, cone crushers, hoppers, and chutes
-
Construction machinery: buckets, blades, and crusher liners
-
Industrial tools: shot blasting machines, hammer mills, grizzlies, and screens
-
Metallurgical equipment: furnace lining, rail car components
-
Rail, cement, and heavy vehicle parts subject to abrasion
