1.4301 is an austenitic stainless steel, usually called 06Cr19Ni10 in China (the old grade is 0Cr18Ni9), with good strength and toughness. Its tensile strength is ≥520MPa, yield strength is ≥205MPa, elongation is ≥40%, and hardness is ≤187HB.

316 stainless steel has good corrosion resistance in normal temperature and low concentration salt water, but pitting corrosion, crevice corrosion or stress corrosion may still occur in high concentration, high temperature or long-term immersion salt water environment.

The performance difference between SUS316L and SUS321 is essentially corrosion resistance and high temperature stability. The former is irreplaceable in medium temperature and high corrosion environments, while the latter is the first choice for high temperature thermal cycle scenarios.

18/10 stainless steel contains 18% chromium and 10% nickel. This high nickel content makes it more corrosion resistant and more resistant to corrosion than 304 stainless steel.

1.4301 stainless steel is one of the most common stainless steel grades, also known as 304 stainless steel.
