Materials Of Cold Drawn Steel Wire
The materials of cold drawn steel wire mainly include carbon steel and alloy steel, including carbon steel such as AISI1064 and alloy steel such as 65Mn, 60Si2Mn, 55CrSi, etc. .
Material type and its characteristics Carbon steel: AISI1064: This is a carbon steel that follows the standards of the American Society of Automotive Engineers. It has high elastic limit and yield strength, but low toughness and is easy to process and cold deform. Its chemical composition includes carbon (0.60-0.70%), manganese (0.60-0.90%), silicon (0.15-0.35%), etc. Alloy steel: 65Mn: It is a high carbon steel with simple composition and low price. Manganese improves hardenability and is suitable for manufacturing various small-section flat springs, round springs, springs, etc. 60Si2Mn: Due to the high silicon content, its strength, hardenability and tempering resistance are higher than those of carbon spring steel, and it is suitable for manufacturing coil springs with a thickness section size of less than 25mm.
55CrSi: It has high fatigue resistance and high relaxation resistance, and is suitable for manufacturing high-stress springs and important mechanical parts.
