FITTINGS AND FABRICATIONS OF 316/316L STAINLESS STEEL Superior Resistance Against Pitting & Crevice Corrosion Acidic & Corrosive Environments Chemical Line Content
Why All 316 Stainless Steel? For the underground piping industry, fi eld replacement of corroded cast iron or mild steel fi ttings installed years before has provided the water and wastewater industry a glimpse into the future of the life expectancy of underground fi ttings in a variety of soil types and surrounding environments. Replacement of fi ttings due to corrsive attack caused by levels of oxygen, carbon dioxide, slightly acidic water, stagnant slow moving waters, and unusual levels of other elements reveal that a more resistant material is often needed to ful fi ll or extend the systems life expectancy. There are many solutions to battle these environmental attacks including fusion applied epoxy coatings and encasement in polywrap & concrete. Another simple solution is to install 316(L) stainless steel fi ttings that will resist the destructive elements naturally. For industrial, plant and process piping, 316(L) stainless steel fi ttings provide the additional resistance to corrosive environments and are compatible with the stainless piping providing the performance and life expectancy for the enrire system. What distinguishes Type 316(L) from Type 304(L) is the addition of 2 to 3% molybdenum. The molybdenum increases the corrosion resistance of the chromium-nickel alloy to withstand attack by many industrial chemicals, solvents and even in the presence of chlorides (such sea water and de-icing salts). Strong, yet lightweight, 316(L) Stainless Steel has an industry wide proven track record in underground, industrial and process piping applications, environmental conditions including extreme temperatures. Selection of Stainless Steel Stainless steel, especially the austenitic 300 series grades, has become a waterworks industry standard with decades of proven corrosion resistant performance in underground, underwater, above ground applications and in treatment and process piping systems. Ranking well above both ductile iron and carbon steel on the galvanic chart for corrosion resistance, stainless steel provides the strength, weldability and heat resistance for pipe fi tting fabrication and applications. Commonly, water and wastewater fi ttings incorporate the 304/304(L) material in various sheet, plate, pipe and cast components. The 304/304(L) grade stainless steel provides corrosion resistance, weldability, machinability and strength at an economical cost. It is the stainless steel most popular for industrial and consumer applications. The same design of fi ttings are frequently o ff ered in the higher grade 316/316(L) stainless steel. While these two grades of stainless, 304(L) & 316(L), have an identical appearance, the 316(L) stainless steel has an addition of molybdenum for improved resistance to chlorides. Nickel and chromium contents are adjusted appropriately to maintain the austenitic characteristics.

What is Passivation and Why Do It? Passivation is a post fabrication (grinding, welding, cutting) metal fi nishing process used to remove any free iron which has deposited on the surface of the stainless steel. The free iron interfers with the chromium oxide layer that covers the stainless surface and protects the underlying alloy from corrosion. Removing the manufacturing free iron debris in the “passivation” process allows the passive layer to reform and returns the stainless steel to its original corrosion resistant state. JCM employs an environmentally safe 2 step process of both a manual removal and a citric acid bath method.

Does JCM Use 316 or 316L? JCM’s design and fabrication process, along with the performance expectations of the fi tting, determines the types and grades of material and components that are incorporated according to their fabrication suitability. • 316(L) stainless steel is commonly made up of 16% chromium, 10% nickel and 2% molybdenum. It is the added molybdenum content that increases corrosion resistance and enhances resistance to pitting (over 304(L) stainless steel). • 316 “L” Stainless Steel is the designation for “Low Carbon” meaning it has less carbon content than 316. Lower carbon content in 316L reduces adverse carbide formation (a result of heating during welding). The 316 and 316(L) Stainless Steel are similar in corrosion resistance when installed in harsh applications (both environment and line content). The 316(L) stainless steel is often used in heavy-gauge welded products because of the lower carbon content which improves wedability. The 316(L) materials reduces the threat of corrosion in the heat- a ff ected zone in oxidizing environments. Another form of 316(L) stainless steel used by JCM is the CF8M (equal to 316 stainless). Cast stainless steel lugs are incorporated into the all 316 stainlesss steel Universal Clamp Couplings (6130 Series). These castings will provide the expected service life of other wrought 316(L) material. For cost and availability purposes, JCM incorporates the 316 material in the fl ange and bolt components. These components can be furnished in 316(L) in specialty ordered products, and the price and delivery time will re fl ect that change. The 316 stainless steel bolting hardware, which is not (L) grade, is a minute factor as the fi nished bolts, nuts and washers are not exposed to welding processes or other manufacturing practices. This process and combination of material grades allows the fi nished pipe fi tting component to provide overall corrosion resistance, remain economic and readily available. 316(L) stainless steel is highly corrosion resistant, and is a preferred material for heat exchangers, chem- ical processing equipement, pipe fi ttings & valves and pump parts, in a variety of process industries. It is preferred in coastal/marine applications where 304(L) would su ff er from chloride attack.
