XC55 Steel
XC55 Steel - High Strength Carbon Steel
Introduction
XC55 steel is an unalloyed carbon steel known for its good mechanical strength and high hardness after heat treatment. Thanks to its medium carbon content, XC55 steel offers an excellent balance between strength, machinability, and heat treatment suitability.
XC55 steel is widely used in the mechanical, automotive, industrial and technical parts manufacturing sectors in Tunisia , Algeria , Morocco and Libya .
At Emirerri Steel , we supply XC55 steel products that meet international standards with standard and custom dimensions.

Corrosion Resistance
XC55 steel has limited corrosion resistance compared to stainless steels. It is recommended to apply:
- Galvanization
- Industrial paint
- Surface finishing
- Anti-corrosion coating
for humid or corrosive environments.
Heat Resistance
XC55 steel retains good mechanical properties at moderate temperatures and can be used in mechanical applications exposed to heat.
Thermal treatment
XC55 steel can undergo several heat treatments:
- Tempering
- Income
- Annealing
- Standardization
These treatments improve hardness, wear resistance, and mechanical performance.
Welding of XC55 Steel
Welding XC55 requires certain precautions due to its carbon content:
- Preheating recommended
- Controlled cooling
- Use of suitable filler metals
TIG, MIG and arc welding processes can be used.
Manufacturing
XC55 steel offers good performance:
- In machining
- At the forge
- With cheese
- Mechanical cutting
- Heat treatment
Applications:
- Mechanical Industry
