AISI Standard Sea Water Use 316 Stainless Steel Pipe Anti Corrosion

Corrosionpedia - An Intro to Pipeline Corrosion in Seawater
For example, stainless steel type 304, which is a commonly used stainless steel, is not safe against the pitting corrosion in seawater. The pitting resistance of stainless steel increases to an acceptable value when 2% molybdenum is added to the chemical composition of stainless steel, which results in stainless steel type 316.
Stainless Steel - Grade 316 (UNS S31600)
316 is usually regarded as the standard “marine grade stainless steel”, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish. Heat Resistance
Corrosionpedia - What is 316 Grade Stainless Steel
316 grade stainless steel is an austenitic form of stainless steel known for its 2-3% molybdenum content. The added molybdenum makes the metal more resistant to pitting and corrosion, as well as improving resistance when exposed to elevated temperatures.

Stainless Steel 316 Tecnical Data
SUS 316 grade has excellent corrosion resistance when exposed to a range of corrosive environments and media. It is usually regarded as “marine grade” stainless steel but is not resistant to warm sea water. Warm chloride environments can cause pitting and crevice corrosion. Grade 316 is also subject to stress corrosion cracking above around

1.4401 and 1.4404 Checker plate- Stainless Steel - TIASCO
TIASCO is one of the few service centres that stocks 316/316L EN1.4404 stainless diamond and tear-drop plate along with the more common 304/304L stainless steel floor plate. We offer a full range of pattern sizes that can ship for immediate delivery. Alternatively, we can custom level stainless checker and floor plate coil to your exact length, reducing yield loss, handling and delivery costs.
Corrosion Behavior of Welded Stainless Steel
Corrosion Behavior of Welded Stainless Steel Corrosion resistance of stainless steel weld metal depends on an understanding of the nature of the protective passive film that gives the steel its "stainless" characteristic BY T. G. GOOCH ABSTRACT. The corrosion resistance of stainless steels depends on a protective,
Pitting and crevice corrosion of offshore stainless steel
Oil and gas platforms regularly use stainless steel tubing in process instrumentation and sensing, as well as in chemical inhibition, hydraulic lines, impulse lines, and utility applications, over a wide range of temperatures, flows, and pressures. Corrosion of 316 stainless steel tubing has been observed in offshore applications around the world.

Sour Service Limits of Dual-Certified 316/316L Steel - TWI
Four-point bend testing on parent and welded dual-certified 316/316L stainless steel, to ISO 15156-3:2003 has shown that these materials are resistant to cracking in sour environments, under a range of chloride concentrations (1 000 and 50 000mg/l) and temperature (60-120°C) significantly beyond the current limits set in ISO 15156-3.
