Gerber e-zout 450 steel question

[Werner Merk]

Hi!
I'm from germany: some months ago i've bought an e-z-out from Gerber.
What kind of steel is 450?
On one side of the blade is engraved: E-Z-OUT U.S.A
On the other side: GERBER 450

I've read some steel-faqs (URL's posted here). But i didnt find 450 steel.
Suppose its some kind of 400 Steel-series.

I've learned from the postings here, that this ATS_34 is better,
and it seems Gerber sells the ez-out with ats-34 blades too.

But how's is this 450 steel compared to other steels?

TIA for your answer!

Werner

P.S I am quite satisfied with the quality of this knive.
It is IMHO really easy to carry with and the blade is sharp
enough for me. I dont use it everyday, but carry it with me everyday.

The 450 is the model number, the smaller version is Model 425. My
Cutlery Shoppe catalog lists the Gerber blade as being 440.

It's 425m (modified) steel - (approx. the same as AISI 440A or DIN
X50CrMoV15)

Have a look on Joe Talmadge monthly steel FAQ for futher description.

The EZ Out is a good blade (with 440 stainless). I've had two and recommend
them. The ATS_34 steel is the better model though (I can't really fault it
in a knife of this size). Unfortunately, they don't appear to sell the
smaller model with the same steel...

do they make an AST-34 model i could have sworn that they make one but i
could have made one?

BTW i will be at camp for the next two weeks so this is my address while i
am there.

P.s. sorry about the col. i may have to get the applegate folder

Hmm... I tink that 450 maybe might just be the model number. Duh?

Sorry, I don't know about that sort of steel. I am usually impressed with
Gerber quality. Does it seem to be stainless or carbon steel?

If stainless, you may be right it is in the "400" series, martensitic
age-hardenable stainless, harder than some and mopre corrosion resistant
than others.

These may be relevant:

steelforge.com says that "Custom 450" 'splits the differecne between'
austenitics and martensitics, balancing "strength" and corrosion resistance.
Global Spec and allforge seem to use exactly the same laguage - maybe it is
a proprietary mix?

http://crswnew.cartech.com/wnew/TechArticles/TA00009.html
says:
"Another stainless steel category covers the age-hardening or
precipitation-hardening alloys such as Carpenter Custom 450� stainless,
Custom 455� stainless and Custom 630� (17Cr-4Ni) stainless. They provide
corrosion resistance at a strength level unavailable in the 300 or 400
series stainless steels."

MatWeb quotes Carpenter:

Material Notes: Data provided by Carpenter Technology Corporation.

Custom 450� stainless is a martensitic age-hardenable stainless steel
which exhibits very good corrosion resistance (similar to that of Stainless
Type 304) with moderate strength (similar to that of Stainless Type 410).
the alloy has a yield strength somewhat greater than 100 ksi (689 MPa) in
the annealed condition, but is easily fabricated. A single-step aging
treatment develops higher strength with good ductility and toughness. This
stainless can be machined, hot-worked, and cold-formed in the same manner as
other martensitic age-hardenable stainless steels. A particular advantage is
ease of welding and brazing. Custom 450 stainless is generally supplied in
the annealed condition, requiring no heat treatment by the user for many
applications. Because it has corrosion resistance like Type 304 stainless
but three times the yield strength, it has been used in applications where
Type 304 was not strong enough. On the other hand, it has also replaced Type
410 stainless directly on a strength basis where Type 410 had insufficient
corrosion resistance. Mechanical properties will depend on the aging
temperature selected.

Custom 450� is a registered trademark of Carpenter Technology
Corporation.

By the way, what shape is the blade? Does it seem to be welded or brazed?

Does "ez-out" seem to refer to how easy it is to open, or perhaps to how
easy it is to pull it out of something you have just stuck it into?

The group is not actually "dead" per se, just greatly reduced in numbers and
activity after some virulent trolls infested it for what seemed like years.

I hope one of the few remaining members of the community will chime in.

In honor of past members, I feel I should suggest:

"Ahh, it ain't as sharp as something handmade from power hacksaw blades
would be!
And they're easy to make!"

and

"Who needs corrosion resistence? Keep it from rusting by smearing it with
lard."

and

"Stainless? Pfui! Might as well be serrated. Now, M2, that's a real MAN's
steel!"

I just had to say that.
