High carbon steel wire Piano wire, also known as piano wire, English: music wire, piano wire, belongs to high carbon steel. Chinese standard: GB4358, American standard: ASTM A228, Japanese standard: JIS G 3522. Material composition: C: 0.80-0.85 Si: 0.12-0.32 Mn: 0.3-0.6 P: below 0.025 S: below 0.025 Cu: below 0.2 The hardness range is 41-60 , allowing a temperature of 120° Piano steel wire is cold-drawn after quenching in a lead bath. It has a very high strength limit and elastic limit. It is the preferred material for small springs and precision springs that are widely used. The quality and performance of the steel wire are strictly required. In addition to the tensile test, tests such as torsion, corrosion, and sharp carbon are also required. According to the use, it can be divided into piano wire used in the manufacture of various important springs, various high-stress and mechanical springs, and valve springs.
