Product Description
DIN Ck55/1.1203 Carbon Structrural Steel
1: Ck55 Steel Introduction
Ck55 is medium carbon high quality structural steel with high strength, good comprehensive mechanical properties, high strength, good machinability and low hardenability. Water quenching is easy to crack, normalizing, tempering after quenching, high frequency surface quenching after treatment are most used. Ck55 steel has a certain degree of corrosion resistance, but it is weak compared to mild steel. When using Ck55 steel, especially in wet or corrosive environments, appropriate measures need to be taken to extend its service life.

7: Ck55 Steel Application
Ck55 is suitable for mechanical parts with high wear resistance, high strength and high elasticity under the condition of small dynamic load and impact. Suitable for hydrogen and argon arc welding, less suitable for gas welding.Ck55 steel is widely used in the machinery manufacturing industry, it is often used in the manufacture of mechanical parts, such as gears, pins, bearings and connecting rods. It is also used in the manufacture of tools, such as cutting tools and impact tools.
