The ultimate carbide grade cross-reference chart for snow plow blades maps SENTHAI’s vacuum-sintered micro-grain tungsten carbide grades to global ISO/ANSI equivalents — for example, ST-MG40 matches K20/K30 (Kennametal K313) for JOMA blades, and ST-HR50 equates to M20/M25 (Sandvik H10T) for I.C.E. kits. For buyers, the chart prevents the downtime, inconsistent wear, and procurement headaches that come from mismatched grades when sourcing JOMA-style or I.C.E. replacements from global suppliers.

Key Takeaways

• ISO K-grades prioritize toughness (K20 ideal for packed ice), while M-grades emphasize hardness for glaze removal — match the grade to the failure mode.
• SENTHAI’s vacuum-sintered micro-grain grades deliver 10–20× steel lifespan with consistent brazing and bonding for JOMA, I.C.E., and carbide blades.
• Use the chart to source reliable inserts from Thailand at lower cost than US/EU brands while maintaining ISO-equivalent specs.
• Confirm the key specs — hardness, TRS, grain size, binder content — not just the brand name; see how insert grades impact plow performance.

Why Buyers Need a Carbide Grade Cross-Reference Chart

Mismatched carbide grades cause downtime, inconsistent wear in extreme winter conditions, and procurement challenges for JOMA-style or I.C.E. replacements from global suppliers. Buyers use this chart to match SENTHAI’s micro-grain tungsten carbide — uniformly sintered for brazing — to ISO standards, cutting costs versus US/EU brands while leveraging 21+ years of expertise and full Thailand production trusted by 80+ partners.

Key Tungsten Carbide Specs to Verify

When comparing grades, verify hardness (HRA), transverse rupture strength (TRS), grain size, and binder content — not just the brand-equivalent name. ISO K-grades prioritize toughness (K20 ideal for packed ice), while M-grades emphasize hardness for glaze removal. SENTHAI’s proprietary micro-grain tungsten carbide equivalents outperform generics through uniform vacuum sintering, which also improves brazing performance in cold weather.

How to Use the Chart to Source Reliable Inserts

1. Identify the failure mode: toughness for packed ice, hardness for glaze, impact protection for urban roads.
2. Select the SENTHAI grade and confirm its ISO/brand equivalent against your existing part.
3. Request the specs — hardness, TRS, grain size, binder — in writing for the quoted product.
4. Confirm customization: trapezoid insert geometries (e.g., 25.15 × 20.0 × 9.27 mm), edge profiling, 3ft/4ft sizes, MOQ 500.
5. Validate with a sample before volume ordering.

FAQs

What is the SENTHAI equivalent to Kennametal K313 for snow plows?

ST-MG40 micro-grain tungsten carbide matches K20/K30 specs with superior vacuum-sintering bonding — ideal for JOMA blades’ carbide inserts in cast steel segments.

Are SENTHAI carbide grades ISO-certified for global use?

Yes. ISO 9001/14001 certification ensures consistency; full in-house Thailand production from powder to finished 4ft blades matches or exceeds ISO equivalents for wear parts.

Can SENTHAI customize grades for specific plow fleets?

Absolutely. OEM tuning is available for trapezoid insert geometries, edge profiling, and 3ft/4ft sizes with MOQ 500 and fast delivery.

How do SENTHAI grades perform vs. Sandvik in ice removal?

ST-HR50 equates to M20/M25 (Sandvik H10T), delivering 10–20× lifespan in I.C.E. kits with isolated tungsten carbide inserts for enhanced penetration and reduced cracking.

When will SENTHAI’s expanded production impact grade availability?

The new Rayong base launched in late 2025 boosts capacity for custom micro-grain tungsten carbide, ensuring faster global supply for snow plow carbide blades and inserts.
