Q-carbon is harder than diamond by 4870% because carbon is metallic in the molten state and gets closely packed, with a bond length smaller than that in diamond. Unlike all other known forms of carbon, Q-carbon is ferromagnetic, with a saturation magnetization of 20 emu/g and an estimated Curie temperature of approximately 500 K.

Q195, Q215, Q235, Q255 and Q275 in the material What is the difference? Carbon steel structural steel is the most widely used, the maximum number of, often rolled into steel, shapes and sections, generally does not require the use of direct heat treated, mainly for construction and general engineering.
Now, this new Q-carbon material is not a super-magnet or something similar, but the mere fact that the material reacts in such a way is fascinating. Even more fascinating, once exposed to small amount of energy, Q-carbon glows. Depending on how the material is made, Q-carbon can end up with diamond nano-needles, or embedded nano-diamonds.

EN 10083 C40 is one mainly of high carbon steel, EN 10083 C40 steel plate is meduim Carbon Steels are similar to low carbon steel except that the carbon ranges from 0.30 to 0.60% & the manganese from 0.50 to 1.65%best q690d carbon content.
Type 304 and 304L Stainless Steel Explained - The BalanceType 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments and it eliminates the need for annealing.
