Steels like YHB-2, MVS-8, and SK-5. Also if you know anything about these steels that would be helpful.
White steel is a common shorthand name for white paper steel (shirogami hagane) which can be any of several fairly simple high carbon, water hardening steel grades. The carbon content varies by grade, and runs from 0.8 to 1.4%. The range of carbon content within a grade is a tight 0.1%. For example, the carbon content of Shirogami Hagani No1A is specified to be between 1.3 and 1.4%. Each grade also contains 0.1-0.2% silicon and 0.2-0.3% manganese, and only trace amounts of the impurities sulfur and phosphorus. Blue paper steel (aogami hagane) is also offered in several grades, with carbon content ranging similarly to the white grades. However, blue steel contains the additional alloying elements chromium and tungsten, and one grade (aogami super) also contains molybdenum and vanadium. The blue steels can be quenched in water or oil, whereas most of the white grades need a faster quench and require water.
