Iron wire refers to a thin wire made of iron-carbon alloy with carbon content below 0.2%.
After quenching, the iron wire cannot be changed into steel wire, and the carbon content has not changed.
Quenching can harden iron wire or steel wire because the metallographic structure changes from pearlite to martensite. The quenching process at home is like this: the steel wire is burned to about 900 degrees. After about 5 minutes, quickly put the steel wire into the water, pay attention to safety and don't burn.
Factory quenching includes water quenching, oil quenching and lead quenching, which are commonly used in wire rope industry.
China ranks first in the world with an annual output of10.8 million tons of steel wire rope. Phosphating wire rope is a revolutionary and innovative technology in the field of wire rope in the world, and its service life (fatigue life) is greatly improved. The historical mission of smooth wire rope has been completed and it has entered the era of phosphating coated wire rope in an all-round way.
1. phosphating coated steel wire rope, the steel wire has been phosphatized by manganese series or zinc-manganese series, and its wear resistance, corrosion resistance and rust resistance have all jumped, and its fatigue life is about 3 times that of smooth steel wire rope with the same structure. Please verify the fatigue life through fatigue test (it is an upgraded product of smooth steel wire rope, and it can also replace galvanized steel wire rope which is plated first and then galvanized, and it is still in short supply).
2. Galvanized steel wire rope, hot dip galvanizing and electrogalvanizing.
3. Stainless steel wire rope, 304 or 3 16 stainless steel.
4. Plastic coated steel wire rope, based on which the outer layer is coated with polyethylene or polypropylene.
5. Smooth steel wire rope will be completely replaced by phosphating coated steel wire rope.
Manganese phosphating coated steel wire rope is preferred for atmospheric environment, and hot dip galvanized-phosphating double coated steel wire rope is preferred for heavy corrosion environment. Please indicate the phosphating coated steel wire rope on the invoice when purchasing, and mark the patent number on the outer packaging of the steel wire rope to prevent being deceived by the smooth steel wire rope, for reference only.
