310S Stainless Steel
Stainless steel 310S is a heat-resistant alloy. It can resist oxidation well in mild cyclic conditions up to 2000°F. Its high levels of chromium and nickel give it good corrosion resistance. It also resists oxidation well.
This material keeps more of its strength at room temperature than common austenitic alloys, like Type 304. Stainless 310S is often used at cryogenic temperatures, with excellent toughness to -450°F and low magnetic permeability.
310S stainless steel is part of the austenitic family of stainless steels. It is known for its high chromium and nickel content. This gives it excellent resistance to oxidation and corrosion. It also has great strength in high-temperature environments.
This variant keeps its structure up to 1150°C. This makes it great for high-temperature uses, like electric heating tubes. Known for its strong performance in tough environments, it offers durability and great resistance to acid and alkali. This makes it valuable in industries that need reliable operation at high temperatures.
Stainless steel 310s contain 25% chromium and 20% nickel, making them highly resistant to oxidation and corrosion. Grade 310S is a lower carbon version, less prone to embrittlement and sensitization in service.
The steels have a lot of chromium and some nickel. This makes them good for use in environments with sulfur and hydrogen sulfide (H₂S). They are widely used in moderately carburizing atmospheres, as encountered in petrochemical environments. For more severe carburizing atmospheres, other heat-resisting alloys should be selected.
In common with other austenitic stainless steels, stainless steel 310S cannot be hardened by heat treatment. They can be hardened by cold work, but this is rarely practiced.
310S stainless steel provides superior corrosion resistance properties against carburization, oxidation and other conditions. It is designed to perform well in high temperatures.
This is important for industries that need strong resistance to carburization and thermal cycling corrosion. It has an austenitic nature at all temperatures and does not become brittle. Its strong resistance to high-temperature oxidation is useful in commercial incinerators, kilns, and food processing equipment.
310S stainless steel can resist high temperatures well. When the temperature goes over 800℃, it starts to soften. The allowable stress also decreases at this point. The highest temperature it can be used at is 1200℃.
The steel pipe has a high amount of nickel (Ni) and chromium (Cr). This gives it good resistance to oxidation and corrosion. It can also resist acids and alkalis, as well as high temperatures.
This type of steel pipe is used to make electric furnace tubes and other products. When the carbon content in austenitic stainless steel is increased, its strength improves. This is due to the solid solution strengthening effect.
The chemical makeup of austenitic stainless steel includes chromium and nickel. It also has molybdenum, tungsten, niobium, and titanium. Its face-centered cubic structure gives it high strength and good creep resistance at high temperatures.
The type 310S has 24-26% chromium, 19-22% nickel, 2.00% manganese, and 1.50% silicon. It also contains 0.045% phosphorus, 0.030% sulfur, and 0.25% carbon. The high chromium enables reduced sulfur atmospheres containing hydrogen sulfide.
The combined effect of chromium and nickel enables high resistance to oxidation. Combined with its low carbon content, the metal is also effective at resisting embrittlement. Manufacturers commonly utilize the metal in extreme conditions, such as furnace manufacturing and heat treating equipment.
Welding Grade 310S is welded with matching electrodes and filler metals. The alloys are readily welded by SMAW (manual), GMAW (MIG), GTAW (TIG) and SAW. Electrodes to AWS A5.4 E310-XX and A5.22 E310T-X and filler metal AWS A5.9 ER310 are used.
Argon is a shielding gas. Preheating and post-heating are generally unnecessary. However, for components exposed to liquid corrosive service, full post-weld solution annealing is essential. Surface pickling and passivation must follow welding to remove high-temperature oxides and restore full aqueous corrosion resistance.
While preheat/post-heat are typically unnecessary, full post-weld solution annealing is critical for liquid corrosion service. Post-weld pickling and passivation are essential to eliminate high-temperature oxides and restore complete aqueous corrosion resistance. This treatment is not required for high-temperature service, but welding slag should be thoroughly removed.
Grades 310S is forged in the temperature range 975 - 1175°C. Heavy work is carried out down to 1050°Cand a light finish is applied to the bottom of the range. After forging annealing is recommended to relieve all stresses from the forging process. 310S Stainless Steel can be readily cold formed by standard methods and equipment.
310S stainless steel, renowned for its superior resistance to high temperatures and oxidation, is extensively utilized across various industries. Its versatility is showcased in a range of applications, including:
Components like conveyor belts, drums, burners, refractory supports, and pipe supports.
