W4Mo3Cr4VSi steel - high speed Tungsten/Molybdenum tool steel. Somewhat close to AISI M2, but has higher Mo and W content, with a little less Carbon. Some dealers claims it performs better than D2 steel, but composition is way different.

Continued adding/adjusting high speed and other tool steel compositions from GB/T standard specification. And working on Steel Chart for android 2.0...

Updated existing and added compositions for Chinese GBT 9943 High speed steel standard code. Most of the GB high speed tool steels now have exact compositions as per the standard. Working on further enhancements.

Custom made, small paring knife. I asked Shinichi to make it for me, according to my specs, for quite specific tasks, basically for veggie prep. Specific tasks, but there's several of them, so it demands rather versatile knife, and so far, this small knife is holding up just about perfect. Chilsel grind edge, to maximize cutting ability and reduce drag, wider than standard paring knife, but about the same length. Can't say it outperforms dedicated knives for harsher cuts, but its holding its own, and I only have to use one knife for preparation of about 20 different vegetables.

I think that one has been around for few months, if not more than that. Value table for elements starting with 0 were not displayed on the graph, although correct value was properly displayed in the table or legend. All displayed properly now.

Kitchen knife superstar in western knives, X55CrMoV15 steel, just got exact specs from the DIN standard. Also, form the same standard, exact specs for the X55CrMo14 steel. I had X55CrMoV15 very close to standard specs, but X55CrMo14 was missing Vanadium, P and S contents. Well, we have exact info now.

Chromium ball bearing steels, from SUJ 1 to SUJ 5 added. Two of them were already in the database, fixed their composiiton according to JIS standard spec. In case you are wondering, thay're closer to very popular AISI 52100 bearing steel, and some closer to 51100 steel.

For the alloys starting with the same character sequence, corresponding mare record ids were not correctly calculated. Fixed and tested.

Added extra element display support in the steel display mode. This was important for non ferrous alloys, since Titanium isn't in the common elements list. Also, some steels contain no so common additives like Titanium, Lead, etc. Data was in the database, but not displayed. All works properly now, so alloys like 60 Nitinol PM, GNiCr40Al4 show properly, and Thyrodur 2762 steel shows full composition including Al and Ti additives.

Technically it is not a steel, but a non ferrous, Nickel Chromium alloy. Invented in US, then copied/modded by Soviets and now produced in China as GNiCr40Al4 steel. I don't know neither American nor Russian names for it, so if you have extra info please let me know.
