Introducing the properties and strength guidelines of piano wire materials from spring trivia.
On this page, we introduce "Spring Trivia" from Sugawara Co., Ltd., which handles important products related to social infrastructure such as electric energy and transportation. Piano wire is a high carbon steel containing 0.75 to 0.85% carbon (C). After heat treatment, it is cold drawn, which increases its tensile strength and gives it high quality strength (the spring is durable) as a practical material. It has low heat resistance and strong magnetism. It is prone to rust, so surface treatment and other measures are necessary. 【Features of Piano Wire】 - High carbon steel containing 0.75 to 0.85% carbon (C) - Increased tensile strength after heat treatment and cold drawing - Low heat resistance and strong magnetism - Prone to rust, requiring surface treatment and other measures, etc. *For more details, please refer to the PDF document or feel free to contact us.
