Galvanized iron wire and galvanized steel wire are two products with carbon content,
The difference in carbon content:
Among them, the carbon content of galvanized steel wire (medium and high carbon steel wire) is 0.40-0.80%, and the strength of galvanized steel wire is relatively high. The manganese phosphating coated steel wire rope is made of high carbon steel wire.
Galvanized iron wire (galvanized wire) low-carbon steel wire with a carbon content of 0.05-0.25%, low strength (that is, relatively soft), commonly known as iron wire, can be used as modified wire, cut wire, tied wire, etc.
