This abstract is a brief summary of the referenced standard. Since I don’t have an internal specification to cite I’ve gone back to referencing F They can either re-test or simply verify mill-cert properties against F and issue another certificate under their own name.

ASTM F – 95 Standard Specification for Stainless Steel for Surgical Instruments

I do not know why and do not see benefit. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

A is widely used whereas F is limited to surgical applications. Distributors will have steels certified to A most of the times. Can someone enlighten me?

It will have a cleanliness requirement. Are you an Engineering professional? The ast, contained in this specification, such as typical hardness values, common heat treating cycles, and examples ff899 selected stainless steels that have been used for surgical instruments, are provided for reference only.

Relatively large distributors can re-certify the material if your company allows. Some implantable grade alloys may have cleanliness requirements. Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.

Now at my current company we have an internal specification for some materials e. Part manufacturers would like flexibility to buy steels from any distributors- small but sufficient quantity at a time.

This is sourcing and inventory issue. The ‘simple’ solution is to spec A but I’d rather understand where the problem lies. The data contained in Tables 1- 4 of this specification, including typical hardness values, g899 heat treating cycles, and examples of selected stainless steels that have been used for surgical instruments, is provided for reference only.

One vendor claimed that F required a vacuum melt vs. Download Now The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays f89 costs.

I believe that A is fine and has no discrepancy. 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 admit there is probably an additional burden to certifying to F but I’m not sure what it is; and that doesn’t necessarily explain the discrepancies in my experience. 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.

I don’t know if it requires re-melting or vacuum melting but those may be needed to meet the cleanliness. The F spec is medical grade material.
