High-temperature resistance of 800℃, with good processing performance, and high toughness, widely used in industry and furniture decoration industry and food and medical industry. Standard marking methods in the market include 0Cr18Ni9 and SUS304, in which 0Cr18Ni9 generally means national standard production, 304 generally means ASTM standard production, and SUS304 means standard daily production.

Hardness is the physical term for the ability of a material to resist local hard material pressing into its surface. The local resistance of solid to external objects is an index to compare the hardness and softness of various materials. There are different hardness standards as different testing methods are prescribed. The mechanical meanings of various hardness standards are different and cannot be directly converted to each other, but they can be compared through tests.
