Carbon Steel S50C / SAE1050 Two Ends Cut Tool Steel Flat Bar
Description
S50C steel is a high-strength medium carbon steel with low cold
plastic deformation, poor weldability, poor hardenability but no
temper brittleness and good machinability.
Normally used in normalizing or quenching, tempering, for the
manufacture of high wear resistance, dynamic load and impact of
small mechanical processing parts and spring parts, such as forging
gears, rod, roll, shaft, friction plate, agricultural Excavation
plowshare, heavy-duty mandrels and so on.

Regular sizes
Big plate: Thickness 10-550mm; width 1600-2200mm; Length
4000-12000mm
Flat bar 1: Thickness 10-550mm; width 155-710mm; Length 1600-2200mm
Flat bar 2: Thickness 10-550mm; width 1010mm; Length 2200-5800mm
Features
1. High-quality high-carbon steel, the use of electric furnace,
open hearth or pure oxygen converter made of all-steel steel,
metallurgical structure with uniform characteristics.
2. The carbon content of the steel (mass fraction,%) ≥ 0.4,
excellent wear resistance, ductility decreased, quenching easy
performance and cracking, so quenching is extremely important and
must be quenched after tempering to avoid temper brittleness.
3. Through the implementation of ball treatment, can improve the
cutting performance of such carbon steel.
4. The steel is usually tempered to a hardness of 19 ~ 22HRC after
use to increase its cutting performance.
Applications
1, For the manufacture of high wear resistance, dynamic load and
impact of the role of small machined parts and spring pieces.
2, Can be used for a variety of cold mold die pad.
3, Standard template material.
