Grade 316 and its variants are known as marine-grade steel. The 316l stainless steel pipe seamless variety is useful in high-pressure applications simply because the load-carrying capacity of this type is almost 20% higher. There is no seam line on the longitudinal section of the 316l stainless steel seamless round tube, which greatly eliminates the occurrence of intergranular corrosion. Since this alloy is a lower carbon version, 316L stainless steel seamless tubing is less likely to suffer from intergranular corrosion. Typically, in the high carbon version of any austenitic stainless steel, when the grain boundaries are sensitized, the excess carbon atoms can form precipitates on the grain boundaries and cause intergranular decay. As with several low-carbon austenitic 300 series stainless sheets of steel, the addition of nitrogen alters the mechanical properties of ASTM A213 TP 316L instrumentation tubing. Nitrogen, for example, increases the yield strength of the material. When the carbon content of SS 316L cold-rolled coiled tubing is reduced, its tensile properties, including yield strength, tend to decrease. The nitrogen present in this alloy compensates for the lack of yield strength in WERKSTOFF NR. 1.4404 heat exchange tubes. It has austenite stabilizing properties while also increasing the alloy's resistance to pitting corrosion. Pitting corrosion is a common problem with 304 stainless steel, especially in marine environments. Therefore, ASTM A249 TP 316L welded pipes are recommended for marine engineering purposes. Especially, the outstanding characteristic of SS 316L ERW pipe is its resistance to pitting corrosion against highly aggressive solutions like phosphoric acid and acetic acid. In addition to its ability to withstand 20% phosphoric acid solutions, UNS S31603 U-tube has proven itself to be a valuable resource in sulfur-containing applications. Grade 304 is standard "18/8" stainless steel. It is the most versatile and widely used stainless steel available, although several alternatives are available; and has excellent forming and welding characteristics. The balanced austenitic structure of Type 304 stainless steel allows it to be severely deep drawn without intermediate annealing. This means that this grade of steel dominates in the manufacture of drawn stainless steel parts such as sinks, hollowware, and pans. For these applications, a special "304DDQ" (Deep Drawing Quality) variant is usually used. Grade 304 can be easily braked or rolled into a variety of components for use in industrial, construction, and transportation applications. It also has excellent welding characteristics. Post-weld annealing is not required when welding thin sections. Grade 304L is a lower carbon version of 304 that does not require post-weld annealing and is therefore widely used for large-gauge components (over about 6mm). Grade 304H with a higher carbon content is used for high-temperature applications. The austenitic structure also gives these grades excellent toughness, even at low temperatures.
