Note: This guide compares HT300 (cast iron) and Q345 (steel), plus adds nitriding treatment benefits—helping you choose materials based on actual needs.
| Aspect | HT300 (Cast Iron) | Q345 (Steel) |
| Core Strengths | High wear resistance, good shock absorption | Excellent toughness, strong impact resistance |
| Cost | Lower (cost-effective for standard use) | Slightly higher (for heavy-duty needs) |
| Weight | Base weight (as in spec table) | ~8% heavier than HT300 (same size) |
| Ideal Workpieces | Small/medium parts (e.g., electronic brackets, small mechanical parts) | Heavy parts (e.g., machinery frames, pressure vessels) |
| Best Working Conditions | Fixed workstations, medium welding frequency, no frequent impact | Mobile stations, heavy welding loads, vibration/impact |
| Maintenance | Low (simple daily check, no complex maintenance) | Regular inspection (avoid deformation from over-impact) |
Nitriding is a surface hardening process that significantly improves material performance—available for both HT300 and Q345.
(1) Key Benefits of Nitriding
1. Harder Surface: Increases surface hardness by 2-3x, effectively resisting scratches from welding tools or parts;
2. Better Wear Resistance: Extends platform life by 50%+, critical for high-frequency welding scenarios;
3. Corrosion Resistance: Reduces rust caused by welding spatter or workshop moisture;
4. No Distortion: Low-temperature process, no platform warping—maintains original precision.
(2) Nitriding for HT300 vs Q345
| Material | Nitriding Effect | Recommended Scenarios for Nitriding |
| HT300 | Boosts wear resistance (fixes “low surface hardness” issue) | Standard workstations with frequent part placement/removal, obvious wear |
| Q345 | Enhances surface strength (maintains inner toughness) | Heavy-duty welding stations with high wear/vibration |
(3)Quick Selection Guide (For Reference)
| Your Need | Recommended Material + Treatment |
| Low cost, standard small-part welding | HT300 (no nitriding) |
| Standard use + longer service life | HT300 (with nitriding) |
| Heavy parts welding/mobile stations | Q345 (no nitriding) |
| Heavy-duty conditions + maximum durability | Q345 (with nitriding) |
This document includes 2 material options (HT300 cast iron / Q345 steel) with clear weight adjustments. HT300 weights are rounded to the nearest 100kg; Q345 weights are approximately 8% heavier than HT300. Special sizes are customizable.
