Can you please elaborate a little more regarding this statement?
It seems to be making too broad a claim... what kind of material are you comparing "16g HHS" to?
When you write "16g HHS", do you mean 16 gauge high speed steel? I Googled HHS on the internet, and the only information I found that makes sense - other than the search switching to HSS - is a link to a type of armor plating.
If you are indeed meaning HHS I have the following problems...
1) Very hard to find.
2) Even if this material is available it would be prohibitively expensive.
3) It would be subject to corrosion due to its carbon content.
4) Probably hard to form by stamping.
Sorry fat fingers,it was supposed to be HSS.
It's not cost prohibitive,most of the KJ(along with every other vehicle) has a lot of it already in the vehicle.All your rear diff mounts and cradle are HSS.Any metal,and I mean any metal, will corrode. Proper care is what keeps from setting in quickly.
The ARB bumpers for KJ's is 100% HSS and I bought one for $600 brand new from 4 wheel parts.It's like 1/8" think and designed to take kangaroo hits at speed.
I suspect that people are getting High Speed Steel mixed up with High Strength Steel.
High strength Steel is a generic term for a range of steel alloys used in many applications.
316 stainless steel is different again. It has many applications including marine, food & chemical industries.
Many appear confused about the term "gauge". 16 gauge is 1/16" thick, 12 gauge is 1/12" thick & so thicker.
There are several newer High Strength Steel alloys available. Most car bodies (fenders etc) are now made of "High Strength Steel". this allows them to be much thinner & so lighter.
If one wants a corrosion resistant alloy steel, it is common to use a NiResist alloy.
316 stainless is widely used. Its biggest limitation is stress corrosion cracking. Weaker, softer alloys are often used to avoid this.
For choosing a suitable steel for use in this application in the rust belt, one should first have a good read of the relevant sections of
'Chemical Engineers Handbook' by Perry et al. Google searches do not provide the necessary technical depth on this.
