A128 GR.B2 Manganese Steel Plates: Durable Toughness for High-Impact Applications

A128 GR.B2 Manganese Steel Plates are designed to withstand heavy wear, high-impact, and abrasive conditions while offering excellent work-hardening properties, toughness, and wear resistance. With initial hardness improving up to 500 BHN under load, these plates deliver unmatched performance in industrial operations.

Features and Benefits

A128 GR.B2 Manganese Steel Plates provide:

• Exceptional work-hardening ability under impact

• High abrasion resistance due to manganese content

• Shock load tolerance and wear resistance

• Good weldability and suitability for cutting, bending, and fabrication

• Compliance with ASTM A128 / B2 specifications

These qualities make the plates ideal for mining equipment, construction machinery, material handling systems, and earthmoving equipment, ensuring reduced maintenance, long service life, and operational reliability.

Applications

A128 GR.B2 Manganese Steel Plates are perfect for industries including mining, construction, material handling, and heavy equipment manufacturing. CNC machining and custom cutting services are available for precise, project-specific applications.
