AISI 420HC stainless steel sheets and plates

AISI 420HC stainless steel sheets and plates

420HC stainless steel holds a higher carbon intake than the 420.

The “HC” in 420HC stands for “high carbon,” and can be brought to a greater hardness than the 420.

Because it can be sharpened to very precise cutting edge and doesn’t rust easily, 420HC stainless steel is the preferred

grade in the commercial knife making industry for cutlery, scissors, surgical tools, and knife blades.

Unlike other grades in the 400 series, the 420HC stainless steel knife blades provide extra strength, hardness,

and wear resistance than other stainless steel grades. It makes a great knife blade for a general purpose knife due to

its ability to resist corrosion and its edge holding capabilities.
