For 6-inch (about 152 mm) common nails, the following is a detailed analysis of their raw materials, materials, surface treatment, packaging and application:
1. Raw materials and materials
6-inch common nails are usually made of low carbon steel to ensure enough toughness and prevent them from breaking when driving.
Common brands: mainly Q195, Q215 or Q235. These brands of steel have moderate hardness and good plasticity.
Processing technology: hot-rolled low-carbon wire rod is cold-drawn into steel wire, and then processed and shaped by nail making machine. Some high-strength special nails (such as cement steel nails) will use 45# medium carbon steel and undergo heat treatment to improve hardness.
2. Surface treatment
Surface treatment mainly determines the antirust ability, and the common types are as follows:
Polishing/blackening: low cost, only a thin oxide film on the surface. Poor antirust ability, suitable for dry indoor environment.
Galvanizing: Galvanizing by electrochemical method, with bright and beautiful surface. Moderate rust resistance, salt spray test can usually pass more than 48 hours.
Hot dip galvanizing: the zinc layer is thick (usually > 40um) and has strong corrosion resistance, which is suitable for outdoor or humid environment, but the surface is rough.
Dacromet/Jiumeite: High rust-proof coating, salt spray test can reach 500-1000 hours, mostly used in high-end industrial scenes.
3. Packaging method
Packaging forms are divided into industrial bulk packaging and retail packaging according to sales channels and usage scenarios:
Industrial bulk: In order to reduce the cost, large cartons or woven bags of 25 kg/case are usually used in bulk.
Small retail boxes: small cartons or plastic boxes of 1 kg, 800 g or 5 lb, which are easy to carry.
Rust-proof and puncture-proof: In order to prevent rust or puncture of the package during transportation, a moisture-proof pad will be added inside the professional packaging box, and a fixing structure (such as a fixing block with a through hole) will be used to fix the nail.
4. Application scenarios
6 “is a long nail, mainly for thick wood connection:
Main uses: heavy-duty wood structure connection, such as the production of foundation pads, outdoor wooden platforms, large wooden cases and pallets.
Selection principle: the length of the nailed workpiece should be 2.5 to 3 times the thickness of the nailed workpiece to ensure the nail holding force.
Construction suggestion: when used in hardwood, it is suggested to drill pilot holes first to prevent wood cracking.
Summary: When purchasing 6-inch nails, it is recommended to choose hot dip galvanizing if it is used outdoors, and ordinary polishing if it is used indoors and has low requirements for rust prevention.
Are you going to use it in outdoor anticorrosive wood scenes? If so, except for hot-dip galvanizing, stainless steel is more expensive, but its antirust effect will last longer. Do you want me to compare the cost performance of the two?
