is this material strong enough for bars forks etc.?

is this strong enough for bars as it is the strongest material my school uses, btw it is a swedish/eu standard not american to clarify. in the school there is equipment to heat up the material to strengthen the welds, a bit like heat treat with this blow torch thing.

Stainless steel = big no-no

 

[mikascooters]

I think 81 and mutts have made, or still are making steel bars, so it could work. If that is the same steel?

 

[Broccoli1]

I don't think that is Stainless- it is listed under Tool Steel.

unfortunately I have no idea what exactly it is.

You should send a PM to Mr. H- he might be more knowledgeable on the EU standards.

You need foam, strongest material out

I'll see your sarcasm and raise you Physics...

"The loss of Columbia was a result of damage sustained during launch when a piece of foam insulation the size of a small briefcase broke off from the Space Shuttle external tank (the 'ET' main propellant tank) under the aerodynamic forces of launch. The debris struck the leading edge of the left wing, damaging the Shuttle's thermal protection system (TPS), which shields the vehicle from the intense heat generated from atmospheric compression during re-entry"

i see your logic and physics and raise you cat

nope, just plain old cat

its not stainless, stainless starts around 2300.

SS 2260 is high alloyed steel according to the second link and it's called A2 steel in the US which is steel for making tool when I googled it.

Maybe that's abit too hard and stiff for bars?

too stiff? you mean it will snap not bend and stuff, i dont want any tomk style falls.

Don't do big sets then

Not sure if i am thinking of the right metal, but I remember my dad saying something about metals used for tools are extremely hard to drill and cut, so they need to be die cast or forged er sumtin...

ill ask my dad when he gets home

That's because they're designed to do the cutting and drilling.

Simple example is a Drill Bit, File or Knife

The metallurgy behind Tool Steels is that they are structured in such a way that when you heat the metal to a certain point it becomes soft.

Now that it is soft you can shape it, cut it, mill it, stamp it etc etc to to whatever Tool you want.

Once this tool shape is created then you can now begin to make the steel hard again. Once this process has been done the Tool steel is extremely hard but also extremely brittle-too brittle for doing any drilling or cutting since it will most likely just snap.

Next step is to take out some of the hardness/brittleness to a point where it still is Hard/Tough but not too brittle.

The Drill bit is another good example of how Tool steel can be affected by heat- you spin a drill bit in a piece of steel too fast and it may create enough heat to take the hardness out of it = worthless Drill bit after that. It is common for people to smoke a drill bit using Home drills because they spin so fast.
