Hard-facing applications demand materials that can withstand extreme abrasion, impact, and high thermal stress. ASTM A128 plates deliver precisely that — a robust foundation for weld overlays and hard-facing treatments, providing enhanced wear resistance and extended component life.
What Are ASTM A128 Plates?
ASTM A128 is a specification covering high-manganese steel plates—typically with 13–14% manganese—that offer exceptional toughness and work-hardening capabilities. These plates serve as reliable substrates for hard-facing, ensuring the overlay bonds effectively while supporting maximum performance.

Why They’re Crucial for Hard-Facing
ASTM A128 plates are vital for hard-facing because they:
- Work-harden under overlay layer stress, improving resilience with use
- Offer excellent impact resistance, even under heavy loading
- Provide a tough core that reduces overlay cracking risks
- Ensure consistent bond strength, thanks to metallurgical compatibility
Trends, Challenges & Common Buyer Questions
Fabricators and maintenance engineers often ask:
- Why is ASTM A128 preferred over standard carbon steel for hard-facing?
- Does welding on A128 require pre-heating or special wire?
- How does A128 perform in high-temperature or impact-heavy overlays?
- What sizes and support documentation does Champak Industries offer?
