FAQ: Chromium Carbide Liner & Related Technologies

What is the core material composition of Chromium Carbide Liner?

Chromium Carbide Liner consists of mild steel (Q235/345) as the substrate and a metallurgically bonded Cr23C6 carbide overlay with hardness up to HRC 62, often containing Si-Mn microalloy modifers for improved crack resistance.

How does wear resistance compare between Chromium Carbide Liner and Manganese Plate?

Chromium Carbide Liner demonstrates abrasion rates less than 0.2mm³/1k cycles (per ASTM G65), typically offering 2–6× longer wear life under the same working conditions compared to standard manganese plate.

What international standards certify Chromium Carbide Liners?

Key standards include ISO 21823 (Overlay Claddings), ANSI/AWS A5.21 (Hardfacing), and comprehensive in-house testing to ISO 6508 (Rockwell Hardness).

Can Chromium Carbide Liner be precision cut and formed?

Yes, CNC waterjet or plasma cutting is used for precision apertures, while moderate cold forming (12–16% radius) is possible for pipe bends and chutes. Pre-heating required for tight bends to avoid overlay cracking.

Is Chromium Carbide Liner suitable for corrosive processing environments?

Yes, the high chromium content (23–29%) offers excellent acid/alkali resistance, outperforming plain manganese or hadfield steel. For critical chemical process lines, a passivation post-processing step is suggested.

What are the thickness and size tolerances for custom liner production?

Typical thickness tolerance is ±1mm, and length/width can be produced up to 3200mm × 2400mm per panel; hole patterns within ±0.5mm.

What is "Hadfield Steel" and how does it differ from Chromium Carbide Liners?

Hadfield Steel is an austenitic manganese steel alloy (usually Mn13), valued for work-hardening impact strength but limited in abrasive wear; in contrast, Chromium Carbide Liners use brittle-hardened overlays to resist abrasive and moderate impact forces.

Conclusion & Authoritative References

With chromium carbide liner, users benefit from longer maintenance cycles, higher equipment uptime, and compliance with international standards such as ISO 21823 and ANSI/AWS A5.21.
