This Supplementary Requirement foot note states that the quality and cleanliness may be specified by the purchaser as equal to or better than that indicated by a designated letter and plate number of Military Standard—430 (latest revision).
I've conducted a google/bing search and cannot locate...
Looking for a source of 1" x 4" x .063" Thick alloy steel test panels with a Nickel of 1.5 - 2.2 or close to that. Any sources? These will be used to verify plating thickness and adhesion of electroless nickel on E4340 material.
Thanks in advance.
Good Day.
Looking for some data on heat treated 17-4Ph stainless steel.
Does anybody have data on A-564 Ty. 630 that has been heat treated at 1400 F for 2-hrs and air cooled and then age hardened at 1100 F (not 1150 F but 1100 F) for 4-hrs and air cooled? We know this is not exactly the...
A material specification table that indicates the Yield to be reported in 2:, and the production part is too small to yield a standard sized specimen, are sub-sized tensile specimens as defined in SA-370 prohibited?
If yes please site the paragraph reference chain.
If no please site the...
ASTM A-540 requires the mechanical tests to be conducted in accordance with the Methods and Definitions in A-370. Para 11.2 of A-370 allows the use of proportional small sized specimens as shown in the noted figure.
When A-540 production pieces are too small to yield a standard sized specimen...
Where does the requirement to have a double barrier for mercury and/or fluorescent light come from?
Is there a MIL Spec or FED Spec with this requirement?
We make fasteners and related hardware to ASTM material Specs. and ANSI and Customer provided drawings. If the item is a repeat then we make enough to stock and ship as needed. Occasionally there are a few issues that arise and I'm looking for comments and/or suggestions. Keep in mind that many...
ASME Section III is very prescriptive when it comes to the use of the yield strength in design calculations, citing a fraction that shall be used (i.e., 1/3rd of the yield strength for design calcs).
.
Is there a similar document establishing the use of the yeild strength for non-Section III design?
Good Day,
. We buy, make and sell fasteners of all types and sizes. What I am looking for is a spot check kit that will allow me to check and verify that we do in fact have zinc plating, or cadmium plating, or chrome plating. I know that in most instances the blue hue or yellow hue will give an...
I will be posting this in the NUCLEAR ENGINEERING OTHER TOPICS forum also.
Colleagues, two questions regarding material certification.
REFERENCE: ASME Section III, NCA-3800(2010) requires a certification for material (para. NCA-3860/3961/3962.1)). Paragraph NCA-3855.5 establishes the...
Is there a 2009b Addenda to the ASME Section II 2007 Edition?
What I've seen in the past follows the 2007 Edition, 2008 Addenda, then a 2009 Addenda. I've not seen a 2009b Addenda.
.
Thanks in advance.
Once an ISO compliant Program has been developed and implemented, can a company self-certify as being ISO compliant and put that on any material related certification?
Stated another way, I am a machine shop owner and the products I supply require a certification indicating the items meet the...
I believe Table 10 of the 1984 version has a typo for the Internal Thread Pitch Diameter for a M20x2.5 (page 45 of the ANSI Standard). Before I purchase the new Standard, can anybody tell me if this has been corrected? The 1984 Table entry is 16.376 / 16.384, and these should be 18.376 and...
What is the difference between a mill that produced bars as COLD-FINISHED, and a specification requirement of COLD-DRAWN?
ASTM A-194 Gr. 1 notes COLD-DRAWN and the mill test report indicates CF (COLD FINISHED) which could be ground to size.
Any comments?
This Spec. calls out two different heat treatments, one for Grade A and one for Grade B. What heat treat process would need to be followed if I wanted to go from one to the other?
Both scenarios have shown up: we have inventoried Grade A and a customer wants Grade B, and, we have inventoried...
What ASME Standard(s) call out the length of a stud? I recollect that somewhere a non-pressure retaining stud is measured end-to-end while a stud used in a pressure retaining application is measured first thread-to-first thread.
What paragraph in what Standard do I find this bit of wisdom...
Please...
ASTM A-574, Alloy Steel Socket-Head Cap Screws, is not specific in the sequential time for the heat treatment: the pieces could be heat treated either with threads or without threads.
Example: Long socket head blanks are heat treated, then when the specific length is needed for an...
A small needle type valve has a pressure rating of 3500 psi and a temperature rating of 900 F but the manufacturer (who is no longer around) doesn't indicate if this is a continuous service rating. What testing must I do to assure myself the stated psi/temp will work in a continuous 3500-psi...
