Alloy 355 is a chromium-nickel-molybdenum stainless steel . Alloy 355 may have an austenitic structure and formability similar to other austenitic stainless steels or a martensitic structure and high strength comparable to other martensitic stainless steels depending on the heat treatment. High strengths may be also be attained by cold working.
330 is an austenitic nickel-iron-chromium alloy metled as AOD melt type. This grade is comprised of approximately 36% nickel giving it excellent high temperature oxidation resistance up to 2200oF. 330 stainless remains fully austenitic at all temperatures and is not subject to embrittlement from sigma formation. It has a solid solution composition and is not […]
Type 420 stainless steel is a general purpose steel and possesses similar qualities to the 410 grade, but contains more carbon which provides improved hardness and strength when heat treated. 420 stainless has good mechanical and machining properties.
Type 403 stainless is a corrosion and heat resistant 12% Cr martensitic alloy, very similar to stainless type 410, with the exception of a slightly lower maximum silicon content and a slightly lower maximum chromium content. Good levels of strength, toughness and ductility may be obtained with this alloy.
