En determinadas circunstancias, puede actuar como ACERO caracter sticas que el AISI-321, pero estabilizado con mejor resistencia a la corrosi n que el 304 debido a sus mayores porcentajes en Cro-mo y N quel. Esta aleaci n es usada para piezas de hornos, contenedores de alta tempera-tura, cordones de soldadura.. Cromo-N quel ACERO con una excelente resistencia a la oxidaci n en ambientes car- carburados y reducidos. El inoxidable 310 tiene una excelente resistencia a las sales templadas, neutrales , cianh dricas y sales de alta velocidad. Los grados 304H, 316H, 321H y 347H son, en cuanto a su composicion quimica, identicos a los 304, 316, 321 y 347, con la excepcion de que el contenido de carbono esta entre 0,04 y 0,10%.

Good strength and excellent resistance to oxidation and carburization. The alloy maintains stable structure during exposure to high temperature. It has high strength and toughness in the temperature range cryogenic to 2000 F (1093 C) which is derived largely from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix.

7 Great resistance to many corrosive environments, such as pitting, crevice corrosion, intergranular corrosion, and stress- corrosion cracking. Has good mechanical properties from moderately to high temperatures. This material is noted for its toughness over a considerable range of temperatures, and has excellent resistance to many corrosive environments. Monel 400 can be hardened only by cold-working. 35 217 MECHANICS PROPIERTIES20520520551535 21720535 18335 201 17035 18320535 21717035 21751520535 21751551551551548551548520535 18340 270240586 Satisfactory resistance in fresh waters and Atmosphere.

8 Very good mecanical work in too very low temperatures Excellent resistance to corrosion of nitrics acids 36 B and sulfonitrics mixtures up to 70 C. His low Carbon content avoid heat treatments after welding. Resists 36 B nitrics acids and phosphorics acids below 70 Resists too enough the oxidation and corrosion. In certain circumstances it could work like refractory steel.. Same properties than AISI - 321 but stabilzed with Niobio. Stainless 309 offers a better corrosion resistance than the type 304 because of higher percentages of nickel and chromium. This alloy has been used for furnace parts, high temperature containers, weld wire, and fire box sheets. Chromium-nickel steel with excellent oxidation resistance to carburizing and reducing environments. Stainless 310 has excellent resistance to drawing and tempering salts, neutral salts, cyaniding salts, and high-speed salts.

9 Resistance to corrosion it s higher than AISI - 316. His low Carbon content avoid heat treatments after welding. Resists 36 B nitrics acids and phosphorics acids below 70 C. Stabilized with Titanium wich avoids heat treatments after welding. High resistance to pitting, stress=corrosion cracking and intercrystalline corrosion. Excellent resistance to moderately aggressive reducing acids. 304H, 316H, 321H and 347H grades,are about their chemist composition equals to 304, 316, 321 y 347, with the exception that the Carbon content it s around 0,04 and 0,10 %.
