This alloy is a nitrogen strengthened austenitic stainless steel that has excellent resistance to corrosion at high temperatures and provides remarkably good properties at elevated temperatures. Nitronic® 40 is about twice the yield strength at room temperature as that of 304, 321, and 347.
Type 316, also known as marine grade or surgical stainless steel, is particularly suitable for applications involving severe corrosive conditions, particularly pitting. Stainless 316/316L maintains strength, durability and workability and is ideal for lasting structural support in corrosive environments with harsh chemicals like salt water, acidic chemicals.
Type 403 stainless is a corrosion and heat resistant 12% Cr martensitic alloy, very similar to stainless type 410, with the exception of a slightly lower maximum silicon content and a slightly lower maximum chromium content. Good levels of strength, toughness and ductility may be obtained with this alloy.
Stainless 317 is an austenitic chromium-nickel stainless steel with excellent corrosion resistance. (317 is a modified version of 316). Its high Molybdenum content enhances the grade’s superior pitting resistance. It is the most corrosion resistant of the 300 Series alloys and possesses the highest tensile and creep strength properties at elevated temperatures.
