1.4401 Austenitic stainless steel seamless pipe

EN 1.4401 Grade 316 stainless steel (16% chromium, 10% nickel and 2% molybdenum) is the second most important austenitic stainless steel compared to 304.

Compared to 304, 316 has added molybdenum and a higher nickel content, giving it greater corrosion resistance in many corrosive environments.

EN 1.4401 offers higher strength and better creep resistance at higher temperatures than 304, and maintains excellent mechanical and corrosion properties at temperatures below 0°C (32°F)

Corrosion resistance and oxidation resistance of 1.4401
316 stainless steel exhibits excellent corrosion resistance and oxidation resistance in a range of atmospheric environments and many corrosive substances, and generally has greater corrosion resistance than 304 stainless steel.

316 is susceptible to stress corrosion cracking at temperatures above about 60°C (140°F) and to pitting and crevice corrosion in warm chloride environments.

It tolerates drinking water with chloride levels up to approximately 1000mg/L at room temperature of 20°C (68°F) to 25°C (77°F) and chlorine at around 60°C (140°F). The chemical content can be reduced to about 500mg/L F).
