What is the most non-porous (most dense) type of steel.
What is the most non-porous (most dense) type of steel.
(OP)
We are currently using surgical stainless that must be polished to a mirror finish. Is there a metal that is less porous or more dense than this? The customer is having problems with chemicals eating into the surface. It must be reflective or be able to be polished to mirror finish. Price is no object.
Thanks in advance.

There are plenty of high strength, high alloy stainless grades that might work.

Some SS that I've seen for medical applications include electropolished 316L and Custom 465®. The former has better corrosion resistance & polishes well; the latter is stronger and harder. Also, lots of 'surgical grade' 304 is polished & buffed for automotive aftermarket exhaust systems.
The closest thing to an 'official' surgical stainless is ASTM F138, 'Standard Specification for Wrought 18 Chromium-14 Nickel-2.5 Molybdenum Stainless Steel Bar and Wire for Surgical Implants (UNS S31673).' I don't have the spec., but it seems to be a high purity, vacuum remelted (VM) version of 316L.
So, like earlier responders, I'd say more application information is necessary.
