Product Description Professional application description of concrete nail.Cement steel nails are exemplary fasteners, uniquely tailored for high-hardness substrates like concrete, brick walls, and stone. Through advanced cold heading forming and quenching hardening techniques, they boast exceptional strength and impact resistance. These qualities make them indispensable in the construction, decoration, and industrial sectors. Below, we delve into their core features, technical specifications, typical application scenarios, and operational guidelines:------1, Core Structure and Material Characteristics1. Material and heat treatmentMain material: Crafted from medium carbon steel, such as the robust C45 steel, or high-performance alloy steel like 40Cr, with a precise carbon content of 0.42% - 0.50%, these materials ensure foundational strength.? Heat treatment process:? Whole quenching: By heating the steel nail to a rigorous 850-900 oC followed by rapid cooling, a formidable surface hardness of HRC52-58 (Rockwell hardness) is achieved, along with a bending strength of ≥ 1200MPa.Tempering and tempering: A secondary heating ranging from 200-300 oC effectively alleviates internal stresses while enhancing toughness, thereby preventing brittle fractures.2. Structural optimization design? Nail tip:Triangular pyramid shape: Featuring a sharp tip angle of 30°, coupled with a surface high-frequency quenching layer (hardness exceeding HRC60), it minimizes penetration resistance and significantly boosts drilling efficiency.Spiral groove engraving: Select models, such as textured cement nails, incorporate spiral grooves on the nail body via precision rolling technology. This enhancement strengthens the mechanical grip with the substrate, elevating the pull-out resistance by 30%.? Nail cap:Butterfly shaped/hexagonal head: This design expands the stress area, effectively dispersing hammering stress to prevent the nail cap from embedding into surface materials like gypsum board.Anti slip rolling pattern: The hat top features a diamond rolling pattern designed to, when paired with a rubber hammer, minimize the risk of hand slippage.------2, Technical parameters and performance comparison[Table]Comparison of Advantages of Cement Steel Nails, Ordinary Round Nails, and Expansion Bolts with Parameter ParametersExpertly suitable for substrates like concrete, brick walls, granite wood, thin steel plates, concrete, and hollow bricks, these nails require no pre-drilling, allowing direct injection into high hardness substrates.Tensile strength ≥ 800N/mm2, significantly surpassing ordinary nails at ≤ 400N/mm2 and closely matching expansion bolts (usually 500-1000N/mm2), while enhancing installation efficiency by fivefold.Shear strength ≥ 600N/mm2, outperforming expansion bolts, with strengths usually ranging 400-800N/mm2, making them ideal for lateral stress applications.Temperature resistance range -40 oC to 150 oC, outperforming ordinary nails (-20 oC to 80 oC) and expansion bolts (-20 oC to 120 oC), making them perfect for outdoor and industrial environments.The cost efficiency of a single nail ranges from 0.1-0.3 yuan/piece, cheaper than expansion bolts which range from 0.5-2.0 yuan/set, offering outstanding comprehensive cost-effectiveness.
