Hardtec is a registered brand name of an alloy known as KDS2000 made by Daido Steel (from Nippon Steel). It's a proprietary stainless grade that has been developed to combine the high corrosion resistance of Austenitic grades like 304 and has the hardness of heat treated Martensitic grades like 410 stainless steel.
Hardtec has a chemistry very similar to 410 stainless steel; but also has 1% of Molybdenum added to it. Molybdenum is the element that gives grade 316 its corrosion resistance improvement over grade 304. Hardtec stainless offers high levels of corrosion resistance, the decline of which was previously unavoidable with heat-treated grades like 410.
There are other stainless steel self-drilling screw options on the market but they each have the following factors to consider:
