Now at my current company we have an internal specification for some materials e. Few part suppliers are willing to ashm the material by their own but rather rely on certs from mills or distributors. The Eng-Tips staff will check this out f89 take appropriate action. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. 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 supplier.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Distributors will have steels certified to A most of the times.

Historical Version s – view previous versions of standard. One vendor claimed that F required a vacuum melt vs.

ASTM F – 12 Standard Specification for Wrought Stainless Steels for Surgical Instruments

Are you an Engineering professional? Since I don’t have an internal specification to cite I’ve gone back to referencing F Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.

You do own current copies of both specs, and any referenced general spec, right? Close this window and log in. Fore example, there is melting requirement for Mo but that is not regulated by F I don’t know if it requires re-melting or vacuum melting but those may be needed to meet the cleanliness.

The data contained in Tables 1- 4 of this specification, including typical hardness values, common heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, is provided for reference only. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Since you are trying to invoke them as contract terms you have better make sure you have copies.

Such issues are the result asrm project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. Classes of stainless steels covered here are Class 3 austenitic stainless steelClass 4 martensitic stainless steelClass 5 precipitation hardening stainless steeland Class 6 ferritic stainless steel.

It’s possibly my memory, but I haven’t admitted that yet. Join your peers on the Internet’s largest technical engineering professional community.

Mechanical property, heat treatment, hardness, and all other requirements except for chemical composition, are governed by the appropriate material standards as specified or as agreed upon between asym and supplier.

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. Register now while it’s still free! Can someone enlighten me?

Part manufacturers would like flexibility to buy steels from any distributors- small but sufficient quantity at a time. In the short term I’ve been able to get around this by agreeing the material certified to A is “compliant” to F and is therefore acceptable. I do not know why and do not see benefit.
