Sorry Earl not all Ductile Iron is created equal...

You may lock this thread now....

 

So what seperates them?

 

I would like to know what seperates the manufactures iron as well. There are tons of companies that advertise ductile iron sleeve inserts what makes one better than the other. I understand the cheaper foundry are producing lower quality but overall what is the biggest differences that you guys have noticed?

isnt ductile iron per the chemistry forumla is Fe-C-Si alloy


one of the benefits from my understanding of chemistry expermiments is the lack of heat treating there by makign it into usable forms.


the other issue from my reading is the stds which is given to ductile iron
first number is minimum tensile strenght per square inch, second is minimum yield and the last is elongation during tensile test percetange.
Grade 60-40-18

Grade 65-45-12

Grade 80-55-06

Grade 100-70-03

Grade 120-90-02

 

i'd say Darton or AEBS.

The heat treating of the iron determines a lot of its characteristics. When its cooling, different microstructures can be formed with different properties depending on temperature cooling curves. My guess among the sleeve companies would be that some have much tighter control over the cooling due to more sophisticated equipment and better quality control.

i figured taht much . its not difficult to work with this specific iron

If that were the case there'd be SSAC sleeve kits on eBay already.

 

many companies have the sleeves under 20 bucks a cyl that i have seen so what makes the competition 100 bucks sleeves vs a 20 buck sleeve

would like to know as well.

 

who makes $20 sleeves?

 

look at la sleeves they make 20 bucks sleeves

 

These are oem replacements, not stand alone sleeves

what were jg's sleeves?

 

i like my aebs but will be switching to a darton sleeve on my new motor setup

 

Within a certain spec.ed material there are tolerances on percentages of the elements included in that specific material. If you wanting to create a desired property within that spec. , you can raise or lower the content of each element and still call it "Ductile Iron". The control of the entire process also adds to elimenating impurities or atmosphere(during heat treat) that cause an undesired affect. All of which will cost more.

dartons permission level is unrestricted user, I dont think he is banned.

 

No he banned me.It says this when I try to open a thread:

"Your have been banned from accessing this site."

 

In before the lock

 

I don't know who the guy you talking about is but maybe you can ban him too or make him pay little more.

I'll wait to Earl comments before I say anything.

 

DARTON

LOVING IT

 

So what was the purpose of this thread again? To stir the pot?! Get a hobby.

 

Not sure because I use and love Darton sleeves.

What happen to Darton's post above? It DISAPPEARED completely
