It’s easy to join and it’s free. Students Click Asstm Join Us! In the astm f899 term I’ve been able to get around this by agreeing the material certified to A is “compliant” to F and is therefore acceptable.
Promoting, selling, recruiting, coursework and thesis posting is forbidden. Astm f899 Item s – asym revisions of this standard. Join your peers on the Internet’s largest technical engineering professional community. It’s possibly my memory, but I haven’t admitted that yet.
The data contained in Tables of this specification, including typical hardness values, common heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, astm f899 provided for reference only.
Now at astm f899 current company we have an internal specification for some materials e. However, F is for surgical instruments non-implantable and do not have such requirements unless it is inherent to the grades.
Resources Digital transformation may be the most astm f899 misunderstood and misused term in business astm f899 today. Large distributors that have many medical-grade buyers or have long term agreements with such customers will have direct certification to F from mills.
Distributors will have steels certified to A most of the times. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. This is sourcing and inventory issue. Mechanical property, heat treatment, hardness, and all other requirements except for astm f899 composition, are governed by the appropriate material standards as specified or as agreed upon between purchaser and supplier.
It includes recommendations and precautions for awtm, cleaning, and passivation of stainless steel parts. Classes of stainless steels covered here are Class astm f899 austenitic stainless steelClass 4 martensitic stainless steelClass 5 precipitation hardening stainless steeland Class 6 ferritic astm f899 steel.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

It includes several alternative tests, with acceptance criteria, for c Mechanical property requirements, heat treating requirements, hardness requirements and all other requirements except chemistry are governed by the appropriate material standards as referenced below or as agreed upon between the purchaser and f8999. Historical Version s – view previous versions of standard.

Can someone enlighten me? Posting Guidelines Promoting, astm f899, recruiting, coursework and thesis posting is forbidden. The data contained in Tables 1- 4 of this specification, including typical hardness values, astm f899 heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, is provided for reference only.
This specification covers the chemical requirements astm f899 wrought stainless steels used astm f899 the manufacture of surgical instruments. Since you are trying to invoke them as contract terms you have better make sure you have copies. A is widely used whereas F is limited to surgical applications. The ‘simple’ solution is to spec A but I’d rather understand where the problem lies.
The F spec is medical grade material. The data contained in Tables of astm f899 specification, including typical hardness values, common heat treating cycles, and astmm astm f899 selecte I don’t asttm if it requires re-melting or vacuum melting but those may be needed to meet the cleanliness. Over the past three decades, 3D printing has developed a reputation as an essential manufacturing process for prototype parts.
Relatively large distributors can re-certify the material if your company allows. Fore example, there is melting requirement for Mo but that is not regulated by F However, now I’m getting notice from vendors that they are not able to source that material unless they buy astm f899 considerable minimum qty which is no good for price or time.
They can either re-test or ff899 verify mill-cert properties against F and issue another certificate under their own name. I believe that Astm f899 is fine and has no discrepancy. Part manufacturers would like flexibility to buy steels from astm f899 distributors- small but astm f899 quantity at a time. The data contained in this specification, such as typical hardness values, common heat treating atm, and examples of selected stainless steels that have been used for surgical instruments, are provided for reference only.
You do own current copies of both specs, and any referenced general spec, right? Mechanical property, heat treatment, hardness, and all other requirements except for chemical composition, are governed by the appropriate material standards as specified aetm as agreed upon between purchaser and supplier.
