Maraging steels Age hardening: hard and tough,very low shrinkage


— Maraging = "mar"tensite + "aging" [treatment]

— Low-carbon steels with martensitic structure•e.g. 18 Mar 300 / 1.2709 / X 3 NiCoMoTi 18 9 5 has 0.2% carbon

— In solution-annealed condition has high strength (~1,000 MPa) but can be easilymachined

— Age-hardenable up to approx. 55 HRC hardness and much increased strength•e.g. 6 hours at 490°C

— Originally developed as high-strength steels for aerospace, also conventionallyused for injection moulding tools with particularly complex cavities

Source: Mold-Making Handbook, ed. Menning, 1998

Maraging steels are high performance, hardenablesteels typically used for e.g. aerospace and tooling

Characteristics of standard maraging steels


— "Maraging steel is an iron alloy which is known for possessing superior strengthwithout losing malleability. ... Maraging steel is essentially free of carbon, whichdistinguishes it from most other types of steel. The result is a steel which

•Possesses high strength and toughness•Allows for easy machining with minimal distortion•Has uniform, predictable shrinkage during heat treatment•Can be easily nitrided•Resists corrosion and crack propagation•Can be finely polished"

— Maraging steels "Offer the best available combination of ultra-high yield and tensilestrength, ductility and fracture toughness of any ferrous materials. Can retainstrength at least up to 350°C. ... Readily machinable. .... Possible to finish-machinebefore aging. Very little dimensional change after aging treatment. Parts uniformlyharden throughout the entire section because they have high hardenability. Exhibitgood weldability."

Source: www.wikipedia.org, 2006

Maraging steels are noted for their high strength,high crack resistance and simple hardening

Quotes from www.wikipedia.org


— "Maraging steels work well in electro-mechanical components where ultra-highstrength is required, along with good dimensional stability during heat treatment.Several desirable properties of maraging steels are:

• Ultra-high strength at room temperature• Simple heat treatment, which results in minimum distortion• Superior fracture toughness compared to quenched and tempered steel of similar strength level• Low carbon content, which precludes decarburization problems• Easily fabricated• Good weldability"

— "As compared with martensite-hardenable carbon-containing steels, carbonlessmaraging steels show, for the same strength, a substantially greater resistance tobrittle fracture, which is their most remarkable merit. On tempering to the maximumstrength, the ductility indices and impact toughness, though diminish somewhat, stillremain rather high. The high ductility of the carbonless matrix and the high dispersityof uniformly distributed intermetallic precipitates are responsible for a very highresistance to cracking, which is the most valuable property of modern high-strengthstructural materials."

Maraging steels are noted for their high strength,high crack resistance and simple hardening

Quotes from www.key-to-steel.com


— "Maraging in Tool & Die Making•Maraging has a significant cost advantage over other alloys. Uniform predictableshrinkage during heat treatment means Maraging does not require excessivereworking. It is easily machined. Its hardness and strength allow it to withstandthe repeated pressures of compression molding for longer tool life with a very goodsurface finish."

— "Maraging in Manufacturing•Maraging's ability to expand without cracking make it the material of choice for drillchucks. Its uniform machinability and durability make it ideal for producing gearsin sophisticated robotic arms in assembly lines, and its high strength and wearresistance make it perfect for grippers in automation lines. Other Maraging(Vascomax) benefits for the manufacturing arena include excellent polishability andweldability with pre- or post heating."
