 JIS S58C Introduction

S58C High Carbon Steel

S58C (JIS G4051) is a kind of high strength medium carbon steel, high strength, hardness and elasticity,but workability is not high, low cold deformation plasticity, low hardenability, water quenching have a tendency to crack, so large parts not suitable for hardening. S58C (JIS G4051) more used in normalized condition, S58C (JIS G4051) is only suitable for small parts quenching, poor weldability,andS58C (JIS G4051) is not sensitive in temper brittleness .
JIS S58C Usage
(1) bridge steel plate 
(2) boiler steel plate 
(3) shipbuilding steel plate 
(4) armor steel plate 
(5) automotive steel plate 
(6) roof steel plate 
(7) Structural Steel 
(8) electrical steel (silicon steel) 
(9) stainless steel spring plate 
(10 ) solar panels
