Specifications: Standards and Classifications
Maraging Steel Rod is governed by standards such as SAE AMS 6512, AMS 6514, and AMS 6515, ensuring quality across grades like 200, 250, 300, and 350, which indicate approximate tensile strength in thousands of pounds per square inch (ksi). These standards define properties like ultra-high strength, toughness, and dimensional stability. For instance, a Maraging 250 Steel Rod aligns with AMS 6512 for general high-strength applications, while Maraging 350 offers superior strength and hardness per the same spec. Classifications include nickel-rich martensitic grades, with compositions typically featuring 15-25% nickel, cobalt, molybdenum, and titanium, further distinguished by heat treatment conditions like solution annealed or aged finishes. Maraging Steel Rod, typically ranging from 8mm to 180mm in diameter, adheres to these standards and is often tailored for precision engineering applications.
Size Range: Dimensions and Customization
Maraging Steel Rod comes in a wide range of sizes to suit diverse needs. Common dimensions include:
- Diameter: Standard diameters like maraging steel rods at 8mm (0.31″) dominate, though options range from 6mm (0.24″) to 180mm (7.09″).
- Length: Standard lengths start at 1m (3.3ft) and go up to 6m (19.7ft), while custom lengths can exceed 10m (32.8ft) for specific variants.
- Custom Options: Suppliers offer cut-to-size services, allowing buyers to specify exact dimensions for maraging steel rod diameter or length needs.
This flexibility ensures Maraging Steel Rod fits everything from small precision components to large industrial builds.
Types: Forms, Processes, and Finishes
Maraging Steel Rod comes in various types and finishes, each tied to specific manufacturing processes:
- Forms: Straight maraging steel rod, maraging steel rod with custom profiles, and textured rod patterns for enhanced grip.
- Processes: Cold-drawn maraging steel rod offers a smooth, precise finish (e.g., bright finish maraging steel), while hot-forged maraging steel rod suits thicker, less polished applications like heavy-duty components.
- Surface Treatments: Options include bright (smooth), matte, No. 4 (brushed), BA (bright annealed), and coated finishes. Maraging steel rod with custom profiles adds functionality with tailored shapes for specific engineering needs.

Frequently Asked Questions
Q: What are the grades of maraging steel?
A: Maraging steel grades are classified by yield strength, including Maraging 200 (~200 ksi), 250 (~250 ksi), 300 (~300 ksi), and 350 (~350 ksi). These grades are achieved through precise alloying with nickel, cobalt, molybdenum, and titanium, followed by a maraging heat treatment process that enhances strength via precipitation hardening.
Q: What is the difference between maraging steel and normal steel?
A: Maraging steel differs from normal steel in composition and properties. It contains low carbon (<0.03%) and high levels of nickel and cobalt, offering exceptional strength and toughness through aging at 480–500°C. Normal steel relies on higher carbon content and quenching/tempering, often resulting in less toughness and corrosion resistance compared to maraging steel.
Q: Is maraging steel expensive?
A: Yes, maraging steel is expensive due to its costly alloying elements (e.g., cobalt, nickel) and the intricate manufacturing process, including specialized heat treatment. This limits its use to high-performance sectors like aerospace and defense.
Q: Is maraging steel the strongest?
A: Maraging steel, especially grade 350 with a yield strength of ~2400 MPa, is among the strongest steels, combining high strength with excellent toughness. However, some experimental alloys or composites may surpass it in specific applications.
Q: Does maraging steel rust?
A:Maraging steel is not inherently rust-proof but resists corrosion better than normal steel due to its low carbon and alloy content. Protective coatings or controlled environments are often used to prevent rust in harsh conditions.
Q: How does Maraging Steel perform in cryogenic applications?
A: Maraging steel performs admirably in cryogenic conditions, retaining toughness and slightly increasing strength at temperatures below -150°C. Its stability makes it ideal for aerospace components and cryogenic storage systems.
