DEFENSE INDUSTRY

Special high-grade steels and critical connection elements with superior mechanical properties for defense industry projects requiring high engineering precision and zero-defect tolerance.

Sector Overview

The defense industry is one of the leading sectors requiring the highest quality and performance standards for steel materials. Zero-defect tolerance, complete material traceability, and superior mechanical properties are fundamental requirements of this sector. At Aktif Celik, we supply special quality steel solutions for Turkey's defense industry projects.

Steels used in defense applications must possess ultra-high strength (1200-2000 MPa tensile strength), superior impact toughness, fatigue resistance, and in some applications, ballistic protection properties. 34CrNiMo6, 300M, AISI 4340, and Maraging steels are the primary grades meeting these criteria. These steels are used in armored vehicles, weapon systems, missile bodies, and aerospace components.

In material procurement for defense projects, full lot traceability, ultrasonic testing (UT), magnetic particle inspection (MPI), and detailed mechanical test results are mandatorily provided. Our products are supplied to meet compliance requirements of MIL-STD, AMS, and NATO STANAG standards.

For your defense industry projects, we serve as your solution partner for critical material needs with our service approach focused on confidentiality, reliability, and full compliance.
