Hot Rolled Carbon Tool Steel Flat Bar With Black Surface S50C /
SAE1050
S50C Tool Steel Bar
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.

Regular hot rolled S50C flat bar sizes
Thickness: 8-250mm
Width: 155-710mm
Length: 2200mm
Mechanical properties
Tensile strength σb (MPa): ≥ 630 (64)
Yield strength σs (MPa): ≥ 375 (38)
Impact toughness value αkv (J / cm2): ≥ 39 (4)
Hardness: None heat treatment, ≤ 241HB; annealed steel, ≤ 207HB
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.
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.
Feature
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.
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.
Through the implementation of ball treatment, can improve the
cutting performance of such carbon steel. The steel is usually
tempered to a hardness of 19 ~ 22HRC after use to increase its
cutting performance.
Delivery Time
