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

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.

Chemical Composition(%)

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.

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

Stock items 15-20 days; customized items 30-50 days.

Packing: Standard export packing; customers' special requests are accepted

Quality Condition

1. Both end of each bar must be cut as require
