The agents are all original packaging from the original factory and imported lines. Piano wire is also called piano wire in English and belongs to high carbon steel. Piano wire is cold drawn after quenching in a lead bath. It has very high strength limit and elastic limit. It is a widely used small spring material. The quality and performance requirements of steel wire are strict. In addition to tensile tests, torsion, corrosion, sharp carbon and other tests are also required. According to the use, it can be divided into piano wire used in manufacturing various important springs, various high-stress mechanical springs and door springs. Chinese executive standards: American executive standards Japanese executive standards Material composition::.:..3:.below:.below:.below, the hardness range is -, the allowable temperature is the material characteristics: used to make strings, valve springs and Steel wire for high stress springs. It has the characteristics of high strength, good elasticity, fatigue resistance, creep resistance and toughness, smooth and clean surface, strong anti-rust ability and excellent musical performance. Carbon spring steel wire () brands are: ~, ~. Piano wire () brands are: ~, ~, ~. B is equivalent to the Japanese piano wire standard. Grade B and grade steel wires are generally made of (,) or (B), and grade B and grade steel wires are generally produced with and (B). Replaced with B.
