17-4 stainless is an age-hardening martensitic stainless combining high strength with the corrosion resistance of stainless steel. Hardening is achieved by a short-time, simple low-temperature treatment. Unlike conventional martensitic stainless steels, such as type 410, 17-4 is quite weldable. Alloy 410 Martensitic Stainless Steel Plate - Sandmeyer SteelAlloy 410 (UNS S41000) is a 12% chromium martensitic stainless steel plate that can be heat treated to obtain a wide range of mechanical properties. The alloy has good corrosion resistance along with high strength and hardness. In the annealed condition, 410 stainless steel plate

The scale on stainless steel consists of oxides of chromium, nickel and/or other alloying elementsin addition to iron, and the ease by which it can be removed depends on base metal composition and the thermal treatment to which it is exposed Resistance to Corrosion - 316 316L - Stainless Steel Tube316 1.4401 / 316L 1.4404 Resistance to Corrosion. Alloys 316, 316L, and 317L are more resistant to atmospheric and other mild types of corrosion than the 18-8 stainless steel.In general, media that do not corrode 18-8 stainless steel tube will not attack these molybdenum-containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum-bearing
General Properties. Alloy 410 (UNS S41000) is a 12% chromium martensitic stainless steel plate that can be heat treated to obtain a wide range of mechanical properties. The alloy has good corrosion resistance along with high strength and hardness. In the annealed condition, 410 stainless steel plate is ductile and may be formed. Selection Stainless Steel For Handling Hydrochloric Acid HClThe common stainless steel types, 304 and 316 should be considered non-resistant to hydrochloric acid at any concentration and temperature. Corrosion resistance of stainless steel The iso-corrosion diagram 0.1mm/year lines are represented for 316 types (red) and a Selection of Stainless Steel for Phosphoric Acid H3PO4At higher concentrations 316 is resistant at higher temperature for any particular concentration i.e. the lines are essentially parallel. The 316 types should be considered if chlorides are likely to be in the acid. Wet process phosphoric acid (WPA) can be aggressive towards stainless steels, depending on the range of impurities that the acid contains.
Depending on acid concentration and the metal involved, sulfuric acid can behave as either a reducing acid or an oxidizing acid. In lower concentrations (up to about 70%) and temperatures on steel or stainless steel, it is reducing. At concentrations over 70%, and into the oleum range, the acid is oxidizing to steel and stainless steel.Design Guidelines for Stainless Steel in Piping SystemsPhosphoric acid Type 304 is satisfactory for storing cold phosphoric acid up to 85% and for handling concentrations up to 5% in some unit processes of manufacture. Type 316 is more resistant and is generally used for storing and manufacture if the fluorine content is not too high. Type 317 is somewhat more resistant than Type 316.
