The molybdenum gives SS 316 better overall corrosion resistant properties than Stainless Steel 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
Stainless Steel 316 has excellent forming and welding characteristics.
It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. SS 316 also has outstanding welding characteristics.
SS 316L, the low carbon version of SS 316 and is immune from sensitisation (grain boundary carbide precipitation).
The difference between 304 and 304L stainless steel is that 304L has a .03 max carbon and is good for welding whereas 304 has a mid range level of carbon.
304 and 304L are austenitic alloys, which means that a nonmagnetic solid solution of ferric carbide or carbon in iron is used in giving this stainless steel its corrosion-resistant properties.

Both AISI 04 stainless steel and 304L stainless steel provide a general purpose stainless steel with good resistance to atmospheric corrosion, to many organic and inorganic chemicals and to food and beverages.
This nickel steel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic.
This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi- purpose plants where such ¡°upset¡± conditions occur frequently.
This nickel alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
Alloy C-22 should not be used in service temperatures above 1250¡ã F due to the formation of detrimental phases which form above this temperature.
Alloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt.
It is commonly referred to by the tradename Hastelloy C22 and the universal designation UNS N06022. C22 has excellent corrosion and oxidation resistance, great mechanical properties over a wide range of temperatures, and good fabrication properties.
Alloy C22 is one of the most corrosion-resistant alloys available, even outperforming C276 and 625. It is resistant to almost all reducing and oxidizing environments, including strong oxidizers, seawater, and organic acids.
C22 has excellent resistance to chloride-induced localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
Hastelloy C-22 (UNS N06022) pipe bends and fittings in stock, allowing for a quick turnaround. Hastelloy C-22 has excellent resistance to aggressive oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
C22 has excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. However, C22 should not be used at temperatures above 1250¡ãF due to the possible formation of embrittling phases.
Hastelloy C-22 is identified by the Unified Numbering System (UNS) designation of?N06022. It is a nickel based alloy with high nickel (56%), chromium (22%), and molyddenum (13%).
C22 is typically provided in the annealed condition with a minimum yield strength of 45 ksi. However, C22 can be cold worked to higher strength levels.
Werkstoff’s number 2.4602, Inconel Alloy 22, VDM Alloy 22 and ATI 22 alloy fall under same UNS number.
C22 can be hot worked or cold worked. However, C22 work-hardens rapidly. Therefore, cold working must often be performed in stages with intervening anneals. Parts should be annealed after cold working.
C-22 is used in severely corrosive media with high chloride and temperature applications such as buffer solutions, active pharmaceutical ingredients (API), fabric softeners, cleaning supplies, and fish, soy and chili sauce.
