Carbon Steel S50C / SS400
S50c is in category of medium carbon which is widespread use in basic task , structural , agricultural ,
machinery equipment as well as mold. Also, widely used in engine part.
Thanks to its various good properties such as strength , tensile, cheap. Moreover, it also can quench
to enchance its strength. Hardness as quenched are at least 58 HRC and can also do induction
S50C is mostly similar to CK45 or S45c. Since most of the properties are in same level, it is widely accepted
for mold, plastic, rubber and parts of mold such as frame, base. And agricultural equipment in any type is popular.
JIS G 3101 SS400 is one of the most commonly used hot rolled general structural steel.
Supplied as plates, sheets, flats, bars, sections etc. They are cheap, excelling in weldability & machinability.
