About MEKQAN

A specialist supplier of high-performance steel bar.

Based in İstanbul, MEKQAN sources special steels and alloys from qualified mills and delivers them finished to drawing — for customers whose components have to hold tolerance under load.

More about us

01Specification first: Every enquiry starts with the grade, diameter, tolerance and finish you actually need — not with what happens to be in stock.
02Finished, not semi-finished: Bars leave us ground and cut to length, so they go straight onto the machine without an intermediate operation.
03Export as standard: Wooden-box packing and full export documentation, delivered to the destination you nominate.

Materials

Grades we supply.

Indicative of our current programme. The portfolio is driven by customer specifications, so treat the list as a starting point rather than a limit.

Full programme

Maraging Steel

Ultra-high-strength precision alloy

A nickel-alloyed martensitic steel that reaches very high strength through age hardening rather than carbon content — with excellent dimensional stability and toughness.

Very high strength-to-weight ratio
Minimal distortion during heat treatment
Readily machinable in the annealed condition

14NiCrMo13-4

Case-hardening steel · EN 10084 · 1.6657

A nickel-chromium-molybdenum case-hardening steel for heavily loaded components that need a hard, wear-resistant surface over a tough, ductile core.

High core strength after carburising
Excellent hardenability in larger sections
Consistent response to heat treatment

Quality

Checked before it leaves us.

Special steel is only worth what its documentation proves. Our control points are deliberately simple and applied to every order.

Mill documentation

Each consignment is released with the mill certification for the grade, traceable to the heat it was produced from.

Dimensional inspection

Diameter, tolerance class and length are verified after grinding and recorded before the material is packed.

Specification check

Material is confirmed against the specification agreed at order stage — grade, condition and execution.

Protected in transit

Bars are corrosion-protected and packed in export-grade wooden boxes built for the freight mode used.

Quality approach

Applications

Where our material ends up.

Different sectors, one requirement: material that behaves predictably once it is machined and loaded.

Precision machining & toolmaking: Ground bar that goes straight to the lathe, with the stability to hold tolerance through the cut.
Automotive & motorsport: Case-hardening grades for shafts, gears and drivetrain components carrying high contact loads.
Energy & heavy equipment: Larger sections where core toughness matters as much as surface hardness.
High-stress components: Maraging and high-strength alloys where strength-to-weight and dimensional stability are critical.
