With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
and spring steel (55Si7 (EN)), in the case of two workloads. Spring steel is generally classified as a low-alloy, medium carbon steel or high carbon steel with very high yield strength. This allows the shaped material to return to their original shape despite significant bending or twisting . Fig.1. Honda CB400 motorcycle strut 2.
Feb 05, 2019 · Leaf spring is one of component that use to vibration damping on vehicle, where one of material that use to fabrication this component is 55Si7 steel. Currently, sustainable product is main focus in industry, so that composite is a potential alternative to replace steel as leaf spring.
See the chemical composition and physical properties of EN 10132-4 Grade 56Si7 +QT, find alternative materials, and connect with suppliers.
All Spring steel grades viz. 55Si7, 60Si7, 65Si7, SUP 9, SUP 11A etc. are used for making of helical and leaf springs which find application in auto sectors and railways.Authors: S R Kumar · K K Keshari · S Kumar · A Chatterjee · S K Ghosh · A K BhakatAbout: Spring steel · Ferroalloy

BBS deliver wire, bar, strip, profile, profil and plate for springs. For example compression springs, tension springs, disc springs, torsion springs, gas springs and leaf springs.
The result is a component with the appropriate combination of hardness, strength and toughness for the intended application. Tempering is also effective in relieving the stresses induced by quenching. Facilities. Open or Sealed Furnace - Hardening, Annealing, Normalizing, Solution
According tensile test, steel of 55Si7 type have 2.92 mm of deformasi total, and 12583 MPa of strain, and composite natural fiber 62.75 mm of deformasi total, and 18590 MPa of stress.
Application: Steel for different types of springs as leaf springs, helical springs, belleville washers. Hot forming and heat treatment: Hot forming: Hot deformation: Normalising: Soft annealing: Hardening: 1050 - 850°C 900 - 830°C 850 - 880°C 650 - 690°C 840 - 870°C/oil min. 55 HRC or 600 HV as quenched Mechanical Properties:
In order to get an indication of the applicability of this structure for gear applications, the rolling-sliding wear test has 245 Proceedings of Sino-Swedish Structural Materials Symposium 2007 been performed in this study. 2 Experimental Work and Analyzes The silicon alloyed steel used in this work was 55Si7 with 0.56 %C and 1.9 %Si.
