Product Announcement from QuesTek Innovations LLC
Ferrium M54 is a new lower-cost, ultra-high strength (293 ksi or 2,020 MPa UTS) and high fracture toughness (115 ksi-√in or 127 MPa-√m) VIM/VAR steel (typical properties) with excellent fatigue resistance, robust thermal processing, and high resistance to stress corrosion cracking (SCC).
M54 was computationally designed to be a lower-cost, drop-in replacement for AerMet® 100 (AMS 6532), yet offer equivalent-or-better properties; M54 contains approximately 50% less cobalt than AMS 6532.
M54 can also be considered when upgrading from Maraging 250, 4340, 300M (BS S155) or other steels to improve performance, or reduce weight or volume. M54 is covered by SAE AMS 6516. It is anticipated that S-basis design allowables for M54 will be approved for use in MMPDS during 2012, and that A- and B-basis design allowables will be approved in 2013.
M54 can be considered for demanding applications, including where superior fatigue resistance and SCC resistance is advantageous. For example, aerospace and defense applications can include landing gear, rotorshafts, driveshafts, arresting tailhooks and hookshanks, actuators, armor, munitions, gun barrels, and blast-resistant or impact containment devices.
Energy industry applications can for example include lifting shafts, driveshafts, couplings or collars, while racing applications can include driveshafts, crankshafts, and connecting rods.
Want corrosion-resistant ultra high-strength steel? See Ferrium S53.
Want a tough, strong core but greater surface hardness? See carburizing-grades Ferrium C61 or Ferrium C64.
Benefits
Benefits of using M54 vs. AMS 6532, Maraging 250, 4340, 300M or other high-strength steels can include:
- Reduce the cost for parts currently using AMS 6532, while also gaining improved material properties. In adition to containing about 50% less cobalt than AMS 6532, M54 has robust thermal processing windows to reduce manufacturing waste/re-work.
- Improve the durability, or reduce the size and weight, of parts currently using 4340, Maraging 250, 300M or other alloys, by leveraging the superior fracture toughness, fatigue resistance and other properties of M54.
- Reduce the occurrence of difficult-to-predict SCC failures of parts currently using 4340, Maraging 250, 300M or other alloys, and related expenses for part condemnation and equipment failure/downtime. M54 has demonstrated approximately 400% greater resistance to SCC than AMS 6532 at OCP, as measured by ASTM F1624.
About Us - QuesTek Innovations LLC
We computationally design materials to directly meet user-defined material needs by using our proprietary Materials by Design expertise and technology.
We rapidly invent, design and develop, qualify and insert new materials into applications to reduce capital, processing, operating or maintenance costs, or to improve environmental protection, competitive supply or competitive advantage.
We estimate that we reduce development times by as much as 50+% and costs by 70+% as compared to traditional material development methods. We are a global leader in the new field of Integrated Computational Materials Engineering (ICME).
Organization and Material Design Experience
While our Materials by Design® computational approach and technology applies to many material systems (including polymers, ceramics, fibers, etc.), much of our current focus is inventing, designing and developing high-performance or environmentally-friendly "green" alloys.
Non-Confidential Information Only
This illustrates some of our non-confidential material design efforts funded by U.S. agencies such as the National Science Foundation, the Department of Energy, various agencies of the Department of Defense. Much of our work for commercial companies/OEMs and others to design new materials is confidential.

Our rigorous stage gate process reduces project costs and risks for our clients, and leverages our technology to rapidly design, develop, qualify and insert new materials into productive service.
We integrate our physics-based, Materials by Design® computational approach and technology with a comprehensive stage gate process. We believe that QuesTek is the first firm to rigorously apply proven stage gate development steps to system-based, computational materials design and development efforts. This yields truly Integrated Computational Materials Design™ and a logical, deliberate methodology to control our client's risks and costs. We typically divide our efforts into three stage gate phases: Phase I Concept Feasibility; Phase II Design and Development; and Phase III Allowables Testing and Qualification.
