Catalog number: HH-4819P Features: ● Corrosion resistance equal to or greater than that of SUS304 stainless steel. ● Approximately twice as strong as SUS304 stainless steel and stronger than SUS410. ● The KDS coating significantly reduces the seizure and galling seen in conventional stainless steel. ● The weakness of stainless steel is that its corrosion resistance decreases when it is heat treated, but Hardtech's corrosion resistance does not decrease even when it is heat treated. ● By using KDS2000, a stainless steel with special alloying elements added, we have succeeded in significantly improving strength compared to conventional stainless steel without losing tenacity and toughness.
