Hay Sterilization

I've heard that boiling hay knocks out nutrients and that 90C/180F pasteurization is better
Is there truth to that rumor? It is a lot easier to boil rather than to try and control temperatures.
I want to start some oyster buckets.

The easy way is rarely the best way. Sterilizing any substrate is bad news. And use straw, not hay

Thanks for the chart re: pasteurization
I don't plan on reinventing anything - as this has all been worked out.
however, I am curious as the difference of using hay instead of straw as substrate. As I understand it- hay is more nutrient rich. Does that make it easier to contaminate?

No. Hay is a grass that is grown to either cut for silage or bale hay. Examples would be timothy, alfalfa, clover, fescue, bermuda, ect. Straw is the stalks of any harvested grain. Examples would be rye, wheat, oat, ect. Hay is cut with a mower and then either chopped up and put in a silo for winter feeding, or raked and baled for winter feeding. Grains are harvested by a combine, which also cuts the stalks down. Then the stalks are raked and baled and used for animal bedding.

what do you call the straw with grains in it then? or is it chaff/hulls you call it, that sticky stuff that gets into dogs pelts when they sleep on it? we call dried clover "silo" over here.. used it for rabbit feed over the winter.

Straw with grain still on it is still straw. Just unharvested. Some get missed

Yeah, I still find some grains in my straw sometimes. The grains in hay are still young, you can see where they will grow but you can barely feel them. I read that even the stalk of hay has more nutrients in it compared to straw since it is cut when it's still young. I bought a bale of hay my first time, we call everything by a different name here so I didn't know what I was buying. It was yellow on the outside so I thought it was straw but once I started cutting it I saw the green.
I didn't risk using it, straw is said to be a mold magnet as it is, decided I would rather not increase my chances for a fail.

Can wood chips or shavings be used for growing Oysters instead instead of straw? Or is FAE a problem with wood?

Substrate material has nothing to do with FAE. Yes you can use wood with oysters

Some say that wood grown oysters taste better. I don't even have an inkling of where I can get wood in my country so straw will have to suffice .

Straw is the dry plant material left over from wheat and other grains after the grains are removed from the heads. There is also oat straw, barely straw etc. With wheat straw the most common in Midwest US. 
Hay is from legumes, such as alfalfa & clover.
Hay is often referred to as green manure as it is sometimes used as a "cover crop" by farmers and can be used as fertilizer by tilling it under, as it is high in nitrogen as Azur pointed out...

No forests or logging in my country, all the trees we have were planted ages ago.
There are local companies who sell wood for fireplaces and shit but the ones I found online don't say what type of wood it is. Fireplaces are mostly ornamental here, it never falls below 0C.

I'm looking at local arborists / tree removal companies to get chipped wood. Millwork / cabinet shops have lots of hardwood shavings from the planer and jointer machines
Alfalfa rocks for nutrients and typically comes pressure treated in cubes for horsies.
Limewater pasteurization works pretty slick and scales easily for large scale production.
