2pcs OD 20mm JIS Japanese Standard T-SWG Black Alloy Steel Die Compression Springs, Length 15-300mm, 20% Maximum Compression, 10x20x100mm

Made of alloy steel, with high temperature resistance, fatigue resistance, good toughness and other characteristics, high temperature resistance up to 280 ℃ The surface of this spring has been strengthened to improve the strength of the stress concentration point, the spring has a long service life The spring has been processed by more than three times of strong pressure, eliminating the internal stress of the spring before use, avoiding spring breakage, deformation and shortening This mould spring has a rectangular cross-section with rounded corners, which reduces the stress concentration when the spring is extruded and rebounded at high speed Wide range of applications, can be used for mould assembly and fixing, mould opening and closing mechanism, finished product demoulding, vibration damping and buffering, etc.
