I hear new alloy of hitachi is called “Samurai Steel”.
One of revolutional property of this steel is keeping high-accuaracy of dimension at the heat treatment. Very wonderful.

I know this steel.Galling resistance without any surface treatment is very beautiful in my works.But I cant get raw material of this steel in United States.

　Is it one of YSS brand steels?
They are famous specialty steels in Japan.

It is called Kunichika steel in Japan.
Kunichika is a inventers name.So because name of a human lived now in the world very few. it is used now.

In the viewpoint of metallurgy,this steel was also the revolutionary next generation one.

Oh I hear that SLD-MAGIC is the first high carbon alloy with applying both of preciptation of intermetallic conpound and self-lubrication mechanian in the world Metallurgy.
This steel becomes popular in the field of cold press stamping die of high tensile strength steel plate in Asia.

In Japan,Hitachi Metals die steel”SLD MAGIC” becomes popular now.Hitachi won the BEST 10 New Prodacts Japan Brand. Prize of The Nikkan sinbunn in 2006 because of developed steel.Winning simultaneously was toyota Lexus LS460.
The toughness ,wear-resistance,anti-distortion at heat treatment,machinability,weldabily of this steel is superior to other conventional die steel like a AISI D2.Hitachi developed this steel by using ultra mlti system alloy design.

Just a note: it’s misleading to say the company caters to “all nuclear reactor makers”, as plenty of reactor types – such as CANDU reactors – don’t even use that sort of high-pressure containment vessel.

Are there any liquid-fluoride thorium reactors currently in operation?

No, today’s nuclear reactors are the descendants of naval reactors that were not built for safety or efficiency, but for expediency. The present nuclear industry grew out of the naval reactor suppliers, who were convinced/bullied into building “civilian” versions of the same thing.

The inventor of the light-water reactor, Alvin Weinberg, tried to convince the Navy not to push the light-water reactor for civilian deployment, but they ignored him. Instead, Weinberg was developing the fluoride reactor, which was an improvement on all counts except the one that really mattered to the Atomic Energy Commission: the ability to produce weapons-grade plutonium.

This the fluoride reactor couldn’t do, so the AEC undermined its development at every step and finally killed it in favor of a reactor that could do what they really wanted, while ostensibly fulfilling a civilian power mission: the liquid-metal fast breeder reactor.

Charles Barton has an excellent series of posts on the historical background of this sorry era of nuclear development here:
