The most popular stainless-steel alloys for marine applications are 316/316L. These austenitic stainless-steel alloys, thanks to the high amount of nickel and molybdenum, have much better corrosion resistant properties than the more popular 304. This is especially the case for pitting and crevice corrosion in seawater environments.(plate) Aspects of testing and selecting stainless steels for sea Revisiting the Selection of Stainless Steel in Water and (steel) Dec 31, 1994Alloy 31--UNS N08031--31Ni-27Cr-6.5Mo-1.2Cu-0.2N-balance iron--is an advanced 6 Mo stainless steel with increased chromium and nickel, contents for seawater service. In hot seawater the pitting potential of alloy 31 remains high up to 90 C (194 F).
Choose the Right Metal for Your Operating Environment. To determine which grade of steel Prioritize Strength, Ductility, and Toughness. Next, consider these three top mechanical Factor in Form and Process. Austenitic stainless steel is widely available in bar, wire, tube, Consider Your Customers' Preferences. Many designers choose stainless steel for its Manage Material Cost and Availability. Although high-performing austenitic stainless steels (plate) DESIGN GUIDELINES FOR THE SELECTION AND USE OF (steel) Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are 1. Metallurgical Structure. 2. The AISI numbering system namely 200, 300, and 400 Series numbers. 3.
SELECTION AND USE OF STAINLESS STEEL Selection and use of stainless steels in water systems Pierre-Jean Cunat, Euro-Inox, Brussels 1.

Selection Stainless Steel for Sodium Hypochlorite NaOCl. Sodium hypochlorite only exists in solutions. The solution can be unstable, giving off chlorine gas. Sodium hypochlorite is not stable as a solid chemical. The hypochlorites, although alkaline, are oxidising. Commercially concentrated Sodium hypochlorite is around 15-wt %.(plate) Selection of Stainless Steel for Handling Chlorine Cl2 and Revisiting the Selection of Stainless Steel in Water and (steel) Selection of Stainless Steel for Handling Chlorine Cl2 and ClO2. Chlorine is a powerful oxidising agent. It normally occurs as a gas but can be liquefied under pressure at ambient temperature. As a dry gas it does not tend to be aggressive towards stainless steel, but as either a damp gas or dissolved in water it can be a corrosion hazard.
Sulphuric acid has a strong affinity for water, extracting water from its surroundings and hence diluting itself. The result can be that acid thought to be safely concentrated for contact with 304 type stainless steels, say above 90%, can actually attack the steel if water has been picked up.(plate) Stainless steel material selection for swimming pools(steel) grade 316 stainless steel should be selected. A drain can also be positioned in areas where it is subject to occasional splash. This too can leave residual water on the grate and channel, which can cause pitting corrosion and brown spots. Pickle passivated and electropolished grade 316 stainless steel is recommended for this application.
Definition and TypesAustenitic SteelsDifferent Types of Corrosion That Affect Stainless SteelsBy convention, stainless steel is an iron-chromium alloy with a chromium content of more than 10.5%. In effect, beyond this content, under oxidising conditions (oxygen in the air or oxygen dissolved in water will suffice), a thin but stable layer forms and strengthens (see below for increasing Cr, Ni, Mo contents). Depending on its crystalline structure, stainless steel falls into one of five categories austenitic, ferritic, duplex, martensitic and precipitation hardened.See more on suezwaterhandbookStainless Steel Grades and Families Explained - Unified Revisiting the Selection of Stainless Steel in Water and (steel) Stainless Steel IdentifiersUnderstanding The Various TypesStainless Steel Families Four Options with Unique PropertiesCharacteristics of Common Stainless Steel Families and GradesFinal ThoughtsTheres two main labels youll find on most stainless steel alloys 1.
