Debido al peso ligero de la tuberia soldada ASME SA790 de acero duplex UNS S32205, se utiliza en procesos de ingenieria aeroespacial y nuclear. Tambien se utiliza en la industria automotriz y de la construccion debido a su alta resistencia al desgaste y capacidad para trabajar en ambientes de alta tension.

El uso de tuberias sin costura ASTM A790 UNS S32205 (sin costura y soldadas) es adecuado para aplicaciones generales, pero la solucion principal que brindan es el agrietamiento por corrosion relacionado con la tension.

Los tubos super duplex producidos segun la especificacion ASTM A790 se suministran en construccion sin soldadura o soldada. El proceso automatizado para fabricar tubos super duplex no utiliza metales de aporte. Los proveedores de tuberias super duplex recomiendan estas tuberias para aplicaciones propensas a la resistencia general a la corrosion.

No es magnetico, tiene excelentes propiedades mecanicas y exhibe la combinacion ideal de alta resistencia y buena soldabilidad en un amplio rango de temperatura.

La tuberia sin costura ASTM B167 inconel 600 es menos resistente a las soluciones oxidantes fuertes, como el acido nitrico concentrado calentado.

Debido a que la tuberia soldada ASTM B517 UNS N06600 es relativamente inmune a la mayoria de las soluciones salinas alcalinas y neutras, los fabricantes de tuberias Inconel 600 recomiendan estas tuberias para aplicaciones que involucran algunos ambientes corrosivos.

La tuberia Incoloy 800 es una de esas tuberias de alta resistencia que tambien es resistente a la oxidacion y la carburacion. Por lo tanto, estas tuberias se utilizan en aplicaciones donde se requiere resistencia a la corrosion y la carburacion.

Se dice que la tuberia sin costura de aleacion 800 que ha sido estirada en frio tiene buena resistencia a la fluencia y la ruptura. La adicion de cromo hace que las tuberias sean resistentes a la corrosion, mientras que el contenido de niquel las hace ductiles.

ASTM A790 UNS S32205 es un tipo de acero duplex que es una mezcla de diferentes elementos. La composicion del acero SA 790 UNS S32205 es cromo, molibdeno y nitrogeno.

La tuberia soldada ASTM A790 UNS S32205 se fabrica para obtener una resistencia adicional. Los tubos soldados se laminan en caliente, mientras que los tubos sin costura se estiran en frio.Ambos pueden reforzarse aun mas mediante el trabajo en frio, pero hasta cierto punto.

La tuberia SA 790 UNS S32205 se utiliza para aplicaciones que funcionan en ambientes ligeramente corrosivos, de presion y temperatura ligeramente alta. Aplicacion de tuberia sin costura Duplex S32205 UNS en sistemas de purificacion de agua y manejo de aguas residuales y alta precision.

Hastelloy B-3 is a nickel-molybdenum alloy with excellent resistance to pitting, corrosion and stress corrosion cracking and better thermal stability than alloy B-2. In addition, this nickel-steel alloy is highly resistant to knife-line and heat-affected zone attacks.

Incoloy Alloy 800 is widely used in equipment that must have high strength and resistance to oxidation, carburization and other harmful effects of high temperature exposure. For services requiring optimum creep and rupture properties, use Incoloy 800H or 800 HT. The high content of nickel and chromium in the alloy also provides good corrosion resistance.

AS1210 Prequalified Incoloy 800 can be used at 800¡ãC. ASME codes allow Incoloy 800 to 815¡ãC, and Incoloy 800H and 800HT to 982¡ãC.

ASTM B163 B407 ASME SB163 SB407 N08800 Incoloy 800 Seamless Pipe is especially suitable for high temperature equipment in the petrochemical industry because the alloy does not form an embrittled sigma phase after prolonged exposure to 1200¡ãF (649¡ãC).

The chromium and nickel contents of this alloy provide excellent oxidation resistance at low concentrations of oxidizing and reducing sulfur, good resistance to carburization and sulfidation. The alloy also has reasonable resistance to nitriding in cracked ammonia, but not as much as Inconel 600.

Incoloy is a group of superalloys with good electrical resistance and tolerances. Incoloy 800 is an alloy of iron, nickel and chromium. These alloys are extremely resistant to corrosion and oxidation. They are not easily deformed or broken down under extreme pressure and heat. The alloy has medium strength and Incoloy 800 material has excellent mechanical properties.

Incoloy 800H and 800HT are typically used in parts above 1100¡ãF where creep and fracture resistance is required. The chemical balance allows nickel steel alloys to exhibit excellent resistance to carburizing, oxidizing and nitriding atmospheres. Incoloy 800HT will not become brittle even after prolonged use in the 1200-1600¡ã F range where many stainless steels become brittle. 800HT exhibits the excellent cold forming qualities normally associated with Nichrome.

Incoloy 800H is a high carbon grade of these 800 alloys. These alloys exhibit excellent resistance to post-weld carburization and graining. They remain ductile for extended periods of time at temperatures below 700 degrees Celsius.

Alloys 800, 800H and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization at high temperature exposure.

Manufactured from 304/304L or 316/316L stainless steel with milled inside and outside diameters (ID/OD). These stainless steel welded joints meet ASTM A403, ASTM A960, MSS SP-4, ASTM B16.9 (except for walls), and MSS SP-43.

INCOLOY Alloy 800 (UNS N08800/W. Nr. 1.4876) is a widely used material for the manufacture of equipment requiring corrosion resistance, heat resistance, strength and stability, operating temperatures up to 1500¡ãF (816¡ãC) ).

Type 304 stainless steel is an austenitic grade that can be drawn very deep. This characteristic has resulted in 304 being the primary grade used in applications such as sinks and pans.

For applications requiring higher resistance to stress rupture and creep, especially above 1500¡ãF (816¡ãC), use INCOLOY Alloys 800H and 800HT.

304 has good oxidation resistance in intermittent duty up to 870¡ãC and continuous duty up to 925¡ãC. However, continuous use at 425-860¡ãC is not recommended. In this case, 304L is recommended because of its resistance to carbide precipitation.

UNS N10665 or W.Nr. 2.4617, Hastelloy B2 (also known as “Alloy B2”), is a solid solution reinforced Ni Mori with low additions of carbon, silicon and iron. It can be used to reduce chemical environment and chemical processing industry. However, Hastelloy B2 should not be used in temperatures from 1000¡ãF to 1600¡ãF and should not be used in oxidizing media.

All stainless steel fabrication can only be done using tools designed for stainless steel materials. Tools and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross-contamination of stainless steel with easily corroded metals that may discolor the surface of processed products.
