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.

Added and corrected all AISI 10xx series steels in the database. To be precise, all of the steels starting from 1044 and ending with 1095 steel are now in the database and now have exact specifications as per SAE standard. Corrected 1018 steel composition and added 1020 steel composition. Neither of those two is a good knife steel, but both areused in pattern weld damascus.

Special thanks to Fellow foodie - khman, for finding the problem. It was missing Cobalt in the composition, whooping 8.50% of it ;) One of the elements that makes this steel go up to 70HRC working hardness.

THere was a problem in JavaScript, for the case when single alloy was loaded in comparison mode. Exception was preventing proper data initialization, even though user interface looked ok. The correct record index was not added to the internal query string builder data, so adding a new alloy to comparison list was resulting in missing data on some occasions. Fix was successfully tested, and you might need to force page refresh to get a new version of the script.

Fixed existing compositions and added missing ones for the Japanese, JIS standard SK series tool steels. Straight from the JIS G4401 standard, 2006 edition. So the data is precise. Also, added corresponding W-Nr and some of the GOST names I cold find.
