Understanding MIL/AMS-T-9046 Supersession

In the early 1990’s, US Secretary of Defense, William J. Perry, was at the forefront of military specification reform. Perry encouraged the military to use Non-Government Standards and do away with outdated military specifications, asserting that doing so would reduce government oversight and lower costs.

In September 1999, MIL-T-9046J was cancelled, and superseded by SAE AMS-T-9046. AMS-T-9046 was a word-for-word translation of MIL-T-9046J Amendment 2, with minor editorial and format changes. Unfortunately, AMS-T-9046 still covered nearly 20 grades of titanium and multiple conditions, rendering it somewhat complicated for users. In May 2006, AMS-T-9046 was cancelled as well, referring future procurement for each alloy and condition to a separate AMS specification.

If your contract requires use of the superseding specification, refer to the table below pointing to the Superseding Specifications for several material designations within AMS-T-9046.

Understanding Specification MIL-T-9046 – Which Grade Do You Really Need?

Back in 1955, specification MIL-T-9046 was born, covering Titanium Sheet, Strip, and Plate. This specification tends to cause a lot of confusion for clients because it covers nearly 20 different types of titanium, and several conditions within some of the alloys. On top of that, during several revisions of the spec, a new alloy designation code was given to each type. We hope the following table and discussion helps to ensure procurement of the right type of titanium for your requirements.

The above table appears in the back of MIL-T-9046J (available for free download at http://assist.dla.mil), but we like our version better. *If you agree, you are welcome to email us at sales@performancetitanium.com and we will gladly share a copy.

Back to the good stuff. Specification MIL-T-9046 was cancelled in September 1999. Its last active revision was “J”, and the code designations for that revision are featured in the far right column of the above table. In the MIL-T-9046 cancellation notice, future acquisition was directed to SAE AMS-T-9046, which is also now cancelled. If your contract requires use of the superseding specification, refer to this discussion for help.

Since the MIL-T-9046 specification has been used for decades, often times a drawing will call out an old code such as “MIL-T-9046 Type 3 Comp C”. Using the table above, we can determine that “Type 3 Comp C” means the requirement is for 6Al-4V, and the drawing is pulling from an older revision of the specification, either Revision F or H. These days, it is unusual to procure material whose certifications will still use older revisions. Certifications would most likely display this requirement as “MIL-T-9046J AB-1”. Check with your Sales Rep if you have questions.

The code designations for Commercially Pure grades of titanium were established in the most unfortunate fashion. Under MIL-T-9046 Revision J, Commercially Pure Grade 1 titanium would now be referred to as “CP-4”, Commercially Pure Grade 2 titanium became “CP-3”, Commercially Pure Grade 3 titanium became “CP-2” and Commercially Pure Grade 4 titanium became “CP-1”. If you are unsure which grade you require, please contact us for help. Although the names sound similar, the differences between the grades are significant.

Berkshire Hathaway to buy Precision Castparts for…. $37,200,000,000

This week, Berkshire Hathaway revealed plans to acquire Precision Castparts Corp (PCC) for a whopping $37.2 billion, amounting to Warren Buffett’s largest deal in history. PCC is a Portland, Oregon-based aerospace supplier, manufacturing various complex structural airframe components and other parts for the aerospace and oil and gas markets.

PCC’s organization is comprised of companies dealing in Investment Cast Products, Airframe Products, and Forged Products, including Wyman-Gordon, Special Metals Corp, and Titanium Metals Corp (TIMET). PCC famously purchased TIMET, a major domestic source of titanium mill products, in 2013 for $2.9 billion.

This deal comes off the heels of the $1.5 billion consolidation of Alcoa and Pittsburgh-based RTI International Metals, a global manufacturer of titanium specialty metal products.

Berkshire Hathaway Inc. to Acquire Precision Castparts Corp. for $235 Per Share in Cash

PCC will remain headquartered in Portland, Ore. as a wholly owned subsidiary of Berkshire Hathaway


OMAHA, Neb. & PORTLAND, Ore. – Aug. 10, 2015 – The boards of directors of Berkshire Hathaway Inc. (NYSE: BRK.A; BRK.B) and Precision Castparts Corp.

Slight drop in Q2 ATI Surcharge

The second quarter is upon us, and ATI Specialty Materials has published new titanium surcharges. However, nothing to write home about.

ATI’s RMS (raw material surcharge) is published quarterly, and fluctuates based on critical elements used in the melting of products.

ATI 6AL-4V and 6AL-4V ELI Bar and Plate Surcharges dropped to $5.15/lb, down a whopping 3 cents from the prior quarter.

CP Grades 2 and 4 remained stable at $3.70/lb for Bar and Plate.

ATI Surcharge Holds Steady

The first of the year brought a newly published quarterly titanium surcharge from ATI, with no significant changes.
The 6AL-4V titanium bar and flat products surcharges dropped a penny from last quarter, to $5.18/lb. The 6AL-4V ELI surcharge followed suit, listing at $5.18/lb.

Commercially Pure Grades 2 and 4 held firm from fourth quarter 2014, at $3.70/lb for bar and flat products.

Though surcharges remain flat, lead times have greatly extended at various domestic titanium mills. Small diameter products may require 30+ weeks lead time, while larger diameters and plates are running 14-22 weeks.

ATI Raises Titanium Surcharge for 6AL-4V

ATI Allvac has marginally increased its raw material surcharge for 6AL-4V titanium products.

Surcharge changes are currently released on a quarterly basis.  The fourth quarter surcharge on 6AL-4V titanium bar products is $5.19/lb, up from $4.98/lb for the third quarter. The surcharge has been creeping upwards since the second quarter of 2014, when it charted its first increase in two years.

The Commercially Pure Grade 2 surcharge remained flat at $3.70/lb for bar and flat products.
