Feb 25, 2018 · Its the chromium in the 304 and 316 grades that differentiate stainless steel from carbon steel. The chemical composition of stainless steel 316 is almost identical to that of the 304 grade. There are a few distinct differences with the quantities of chromium (18 20% for 304, 16 18% for 316) and nickel (8 10.5% for 304, 10 14
Jan 12, 2021 · Qualities of 316 vs. 316L Stainless Steel. 316 and 316L stainless steel alloys are both marine-grade steels, but they do possess some key differences. 316L has a lower proportion of carbon in its composition. To qualify as 316L stainless steel, the amount of carbon cannot exceed 0.03%. 316/316L/316H Stainless Steel Pipe/TubeGrade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). Grade 316H, with its higher carbon content has application at elevated temperatures, as does stabilised grade 316Ti. The austenitic structure also gives these grades excellent toughness, even down to cryogenic

Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion. Resistance increases with molybdenum alloy content. 317L is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C). At temperatures under 100°F (38°C) this alloy has excellent resistance to solutions of higher ATI 316LNATI 316LN alloy exhibits excellent resistance to oxidation and a low rate of scaling in air atmospheres at temperatures up to 1600-1650°F (870-900°C). The performance of ATI 316LN stainless is slightly inferior to that of ATI 304 stainless steel, which has slightly higher chromium content (18% vs. 16% for ATI 316LN stainless).
AWS A5.9/ASME SFA 5.9 is the specification for welding consumables like wire, electrodes and rods for arc welding of stainless and heat-resisting steels. Duplex class ER2209 gives the balance of Austenite and Ferrite microstructure in the as-welded condition, it contains 22% Cr and 8% Ni so as to offers high strength, excellent ductility and Encore Metals - T-316, T-316L, T-316NT-316L is a low-carbon modification which minimizes carbide precipitation during welding and exposure to elevated temperatures in the 425C/815C range. It can be used in the as-welded condition. T-316N has a higher nitrogen content than T-316 to increase strength with minimum effect on ductility and corrosion resistance.
LDX 2101 - A lean duplex stainless steel offering excellent strength, SCC resistance and economy. 316/316L Stainless Steel - Molybdenum alloyed austenitic stainless. The most popular chemical-process grade. Because welding duplex stainless steel is not fool-proof it is important to perform quality checks. We normally suggest that when How to weld Duplex Stainless Steel.ppt [Read-Only]Duplex Stainless Steel Welding techniques In the flat position there should be no weaving. Vertical up position weaving of up to 20mm is advantageous. For Sub-Arc a 10-15° forehand welding direction increases penetration. This allows the root face edge to be welded up to 8mm.
