Advantages and disadvantages of galvanized stainless steel bolts
Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective method of metal anti-corrosion, mainly used in metal structures and facilities in various industries. The rust-removed steel parts are immersed in a molten zinc solution at about 500°C to attach a zinc layer to the surface of the steel parts, thereby achieving the purpose of anti-corrosion. In the standard parts industry, galvanizing is often used to achieve the purpose of corrosion and rust prevention.
Hot-dip galvanized bolts are also called hot-dip galvanized bolts. After degreasing and derusting, the bolts present a non-polluting and infiltrating surface. They are immediately immersed in a plating tank where the zinc is melted beforehand. A method of forming a zinc coating. The coating of hot-dip galvanized bolts is thick, generally 30-60 microns, and the coating has a high anti-corrosion ability. Steel parts suitable for outdoor work. So, what are the advantages and disadvantages of galvanized bolts, the following standard parts manufacturers will introduce you:
The advantages of galvanized bolts:
1. Strong corrosion resistance, durable;
2. The processing cost is low, and the price is relatively low compared to stainless steel bolts;
Disadvantages of galvanized bolts:
1. The zinc plating of the bolt will reduce the mechanical strength of the bolt thread;
2. The thickness of the galvanized layer is different, which affects the use with the nut;
3. If the process is not handled properly, it will cause pollution.
There are many kinds of electroplating of iron combination screws: ordinary and environmentally friendly. For example: color zinc, generally called red color. White zinc, black zinc, white nickel. Blue zinc. There are environmentally friendly color zinc, environmentally friendly white zinc, and environmentally friendly blue zinc. Environmentally friendly white nickel. There are more advanced ones. Nickel on copper, nickel in brine. Tools/Materials Screw wires, iron screw wires include 1010, 1018, 10B21, etc. Stainless steel screw wires include SUS201, SUS304, etc. Steps/Methods The requirements for the material of the combined screw depend on which material is required, whether it is iron or stainless steel. What is the national standard number of the combination screw? There are GB9074.8 and GB9074.4. There are GB9074.13 and so on. The mechanical performance and strength requirements of the combined screw need not be hardened. The level requirements are divided into 4.8 and 8.8 l...
