XC10 Steel

Introduction

Carbon Steel XC10 is a low-carbon, non-alloy steel grade from the historical French AFNOR designation system. It is characterized by its relatively low carbon content, good ductility, excellent weldability and good formability.

XC10 is primarily used for components that require moderate mechanical strength combined with good fabrication characteristics. Its low carbon content makes it suitable for operations such as bending, forming, drawing, machining and welding.

The grade is commonly compared with modern C10 / EN 1.0301 and SAE/AISI 1010 grades. However, these designations should not automatically be considered identical. Exact equivalence depends on the applicable product standard, chemical composition, product form, delivery condition and Material Test Certificate (MTC).

Carbon Steel XC10 is suitable for general engineering, mechanical components, fabricated parts and applications where high hardenability is not required.

Types of Carbon Steel XC10 Products

XC10 Round Bars

Round bars are suitable for shafts, pins, machined components, mechanical parts and general engineering applications.

XC10 Flat Bars

Flat bars can be used for brackets, supports, fabricated components and mechanical parts.

XC10 Square Bars

Square bars are used for machining, fabricated components, supports and mechanical assemblies.

XC10 Sheets & Plates

Sheets and plates can be used for formed components, fabricated parts, covers, supports and general industrial applications.

XC10 Forgings

XC10 can be used for selected forged components where moderate strength and good deformation characteristics are required.

Corrosion Resistance

XC10 is not a stainless steel and does not provide the inherent corrosion resistance associated with stainless steel grades.

When exposed to moisture, water, chemicals or outdoor environments, XC10 can undergo oxidation and corrosion. Appropriate surface protection may therefore be required.

Common protective methods include:

• Painting
• Powder coating
• Galvanizing
• Zinc coating
• Black oxide
• Oil coating
• Phosphating
• Other suitable surface treatments

For highly corrosive environments, stainless steel or corrosion-resistant alloy grades may be more appropriate.

Heat Treatment

Because XC10 has a low carbon content, it has limited hardenability compared with medium- and high-carbon steels.

Depending on the application, possible heat-treatment processes include:

Annealing

Used to improve ductility, relieve stresses and facilitate forming or machining.

Normalizing

Can be used to refine the microstructure and obtain a more uniform mechanical condition.

Stress Relieving

Used after forming, welding or machining when reduction of residual stresses is required.

Carburizing

For selected applications, XC10 can be carburized to produce a harder surface while maintaining a relatively ductile core.

This combination can be useful for certain mechanical components requiring surface wear resistance without requiring high bulk hardness.

Welding

Carbon Steel XC10 has very good weldability because of its low carbon content.

Common welding processes include:

• TIG / GTAW
• MIG / GMAW
• MAG
• SMAW
• Resistance welding
• Arc welding

For many low-thickness applications, preheating may not be necessary. However, welding parameters should be determined according to material thickness, joint design, restraint, welding procedure and service requirements.

Suitable post-weld treatment may be considered when required by the application.

Machining

XC10 offers good machinability and can be processed using conventional machining methods.

Typical operations include:

• Turning
• Milling
• Drilling
• Boring
• Threading
• Sawing
• Reaming
• Grinding

Machining parameters should be selected according to the material condition, tooling and required dimensional accuracy.

Forming & Fabrication

One of the main advantages of low-carbon XC10 steel is its good formability.

It can be processed through:

• Cold bending
• Hot forming
• Deep drawing
• Rolling
• Press forming
• Stamping
• Cutting
• Punching
• Drawing

Its relatively low carbon content provides good ductility and reduces the risk of cracking during properly controlled forming operations.

Surface Finishing

XC10 can be supplied or processed with different surface finishes depending on product form and application.

Common options include:

• Mill finish
• Bright finish
• Pickled surface
• Ground surface
• Polished surface
• Black oxide
• Zinc-coated surface
• Galvanized surface
• Painted surface

Surface protection should be selected according to the operating environment and required service life.
