C250 Turnning

C250 is a medium-grade maraging steel known for its high strength, toughness, and dimensional stability. This iron-based alloy derives its name from "martensite" and "aging," combining low carbon content with hardening through aging treatment. It contains key alloying elements such as nickel, molybdenum, cobalt, and titanium, which enable the steel to achieve exceptional mechanical properties.

At Dong-A Special Metals, we highlight the strategic importance of C250 steel in high-performance applications and its potential for sustainable recycling.


Key Features and Industrial Applications of C250 Maraging Steel

C250 maraging steel consists primarily of iron (Fe), with 18–19% nickel (Ni), 4.8% molybdenum (Mo), and 7.5% cobalt (Co). It also includes small amounts of titanium (Ti) and aluminum (Al). The carbon content is minimal, under 0.03%, which enhances weldability and formability prior to heat treatment.

After aging, C250 achieves a yield strength of around 1700 MPa and tensile strength above 1900 MPa. These properties make it ideal for:

- Aircraft landing gear

- Missile and rocket casings

- Injection molds and high-pressure gas vessels

- High-strength gears and machine parts

Its superior machinability and dimensional stability ensure that even under high stress, C250 maintains its integrity—making it a preferred material for precision engineering, defense systems, and aerospace structures.


Recycling Value and Strategic Importance of C250 Alloy Scrap

C250 contains expensive strategic metals, including nickel, molybdenum, and cobalt, which adds significant value to scrap recovery. Due to its stability post heat treatment, C250 scrap can be refined into high-purity recycled alloy with minimal degradation in properties.

High-grade scrap often comes from aerospace and mold machining operations. At Dong-A Special Metals, we specialize in recovering and processing this scrap, contributing to metal resource circulation and carbon emission reduction.

In today’s global market, where nickel and cobalt face supply chain vulnerabilities, especially due to geopolitical instability in Africa and rising demand from EV battery production, the recycling of C250 becomes even more crucial. Building a domestic recovery system helps secure strategic resources and reduces dependence on imports.

Looking ahead, C250 maraging steel is poised for broader use in sectors like hydrogen energy, next-generation tools, and space technology, beyond traditional aerospace and defense.


Conclusion

C250 maraging steel combines strength, machinability, and recyclability. As industries shift toward carbon neutrality, the recycling of high-grade scrap alloys like C250 offers both economic and environmental benefits.

Dong-A Special Metals leads in the collection, refining, and redistribution of high-purity C250 alloy scrap.
