Two Ends Cut Tool Steel Flat Bar Annealing Condition For Standard Template Material

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.

Chemical Composition(%)

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.
