Mainstream material grading and parameter comparison
- Cr12MoV HRC 58~62 Low-carbon iron wire, galvanized iron wire High cost performance, good toughness, not prone to chipping Small and medium-sized conventional mass production, general nail factories
- SKD11 HRC 60~63 Medium carbon steel, tempered steel wire Wear-resistant and fatigue-resistant, stable continuous high-speed operation Medium-sized large-scale assembly line
- M2 high-speed steel, HRC 62~65, stainless steel wire, high-hardness carbon steel, high temperature resistance, high-speed thread rolling without burning teeth, production of stainless steel nails, high-strength special nails
- Cemented carbide (tungsten steel) HRA 88~92 Hard steel wire, ultra-high daily production conditions Lifespan is 5~8 times that of mold steel, wear-resistant tip Large factories produce over 10 tons per day
advantages
- 1. High molding accuracy
The coaxiality of the inner and outer circles is ≤0.005mm, the thread profile angle tolerance is ±0.01°, and the pass rate of finished thread inspection using a go/no-go gauge is ≥99.5%;
Cold extrusion forming enhances the compactness of threaded metal fibers, and the tensile strength of nail threads is increased by more than 30% compared to machining processes, making them less prone to slipping or breaking.
2. Durable and wear-resistant, with low downtime
The tooth surface undergoes ion nitriding and carburizing strengthening treatment, providing resistance to seizure and iron chip scratching, and slow wear due to continuous production over a long period of time. Qualified mold steel can sustain the production of hundreds of thousands of nails, while tungsten steel can achieve production in the millions.
