Explore Specifications →New Zealand's industrial topography represents a highly diverse operational environment, spanning from the rich alluvial gold mining fields of Otago and the abrasive ironsand extractions in Waikato, to the vast forestry chipping mills of the Bay of Plenty and geothermal power plants in the Taupo Volcanic Zone. Each of these sub-sectors presents extreme physical wear mechanisms, requiring highly specialized metallurgical countermeasures. Standard carbon steel plates and generic quenched wear steels often fail prematurely when exposed to the dual challenges of intense micro-scratching abrasion and heavy impact load.
As a leading global developer and fabricator, Tangshan Runxing Machinery Co., Ltd. delivers advanced Chromium Carbide Overlay (CCO) composite plates designed to survive these environments. Our research demonstrates that utilizing hypereutectic microstructures containing over 30% volume fraction of primary M7C3 chromium carbides yields up to an 8x increase in material service life compared to standard structural steel. In New Zealand, where remote operations make equipment downtime extremely costly, integrating long-lasting wear plate technology directly converts to sustained corporate profitability.
Industrial machinery components deteriorate via several distinct Tribological mechanisms. Our material science division focuses on mitigating the four primary classes of wear affecting NZ assets:
In New Zealand's isolated geographical context, heavy equipment replacement parts carry significant logistics surcharges and lead times. A premature failure of a hopper lining in a plant in Christchurch can halt production for days. Runxing CCO solutions reduce the Total Cost of Ownership (TCO) by minimizing maintenance intervals. Instead of replacing sacrificial liners every 3 months, our engineered plates can last up to 24 months, minimizing physical labor costs, crane rentals, and lost production time.

Under abrasive conditions, Runxing CCO plates outlast standard AR400 or AR500 structural wear plates by 4 to 8 times. Quenched steels rely on martensitic hardness, which can degrade rapidly under high-stress grinding abrasion. CCO plates utilize hard primary M7C3 chromium carbides (1500 HV) bound in a tough eutectic matrix, offering superior wear resistance.
Yes. The base plate (commonly Q235B or Q355B structural steel) is weldable using standard low-hydrogen structural electrodes or MIG welding wires. Pre-heating is recommended depending on plate thickness to control cooling rates in the Heat Affected Zone (HAZ). The hard overlay face cannot be directly welded, so plug welding holes or stud welding from the rear side is recommended for liner installations.
The fine stress relief cracks on the overlay surface are normal features of CCO materials. They occur during the cooling phase of weld cladding to relieve thermal stress. These cracks stop at the fusion boundary and do not propagate into the ductile carbon steel backing, preserving the plate's overall structural integrity.
Through our export representative, Hebei Yuwan International Trade Co., Ltd., we manage all customs clearance and international shipping documentation. Sea freight from Tianjin Port to major New Zealand ports (Auckland, Tauranga, Lyttelton) typically takes 20 to 30 days.
