In the 800°F to 1,562°F temperature range, 321 Stainless is not susceptible to the same level of corrosion as 304 Stainless and is the material grade of choice for applications with temperature ranges up to 1,652°F (intermittent service) and 1,697°F (continuous service).\u003c\/p\u003e\n\u003cp\u003eOur 321 Stainless Mandrel Bends are now available in both 45° and 90° bend options with outside diameters ranging from 1.500\" to 3.500\". Our Mandrel Bends are precision bent using a CNC mandrel bender in an ISO 9001 certified facility to ensure that the degree and centerline radius of each bend is consistent and free of defects. After the bending process is completed each mandrel bend is then de-burred and polished to a 600 grit finish to ensure a clean finish on the ends and surface.\u003c\/p\u003e\n\u003cp\u003eOur mandrel bends are a perfect match for our \u003ca href=\"https:\/\/www.aceraceparts.com\/collections\/tube-stainless-steel\" target=\"_blank\" title=\"Ace Race Parts Stainless Steel Tube for Exhaust and Header Fabrication\" rel=\"noopener noreferrer\"\u003estainless steel Tube\u003c\/a\u003e, stainless steel \u003ca href=\"https:\/\/www.aceraceparts.com\/collections\/v-bands\/stainless-steel\" target=\"_blank\" title=\"Ace Race Parts Stainless Steel V-Band Clamps and Flanges for Exhaust and Header Fabrication\" rel=\"noopener noreferrer\"\u003eV-Band Clamps and Flanges\u003c\/a\u003e, \u003ca href=\"https:\/\/www.aceraceparts.com\/collections\/tube-fittings\/concentric-reducers\" target=\"_blank\" title=\"Ace Race Parts Stainless Steel Reducers and Transitions for Exhaust and Header Fabrication\" rel=\"noopener noreferrer\"\u003eTube Size Fittings\u003c\/a\u003e, \u003ca href=\"https:\/\/www.aceraceparts.com\/collections\/exhaust-turbo-inlet-turbo-outlet-header-exhaust-flanges\/exhaust-flanges-gaskets\" target=\"_blank\" title=\"Ace Race Parts Exhaust Flanges and Gaskets for Exhaust Fabrication\" rel=\"noopener noreferrer\"\u003eExhaust Flanges\u003c\/a\u003e, and \u003ca href=\"https:\/\/www.aceraceparts.com\/collections\/flex-couplings\" target=\"_blank\" title=\"Ace Race Parts Exhaust Flex Couplings and Flex Bellows for Exhaust Fabrication\" rel=\"noopener noreferrer\"\u003eFlex Couplings and Flex Bellows\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong style=\"line-height: 1.4;\"\u003e\u003cb\u003eDETAILED SPECIFICATIONS:\u003c\/b\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutside Diameter\u003c\/td\u003e\n\u003ctd\u003e3.500\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWall Thickness\u003c\/td\u003e\n\u003ctd\u003e16ga (0.065\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInside Diameter\u003c\/td\u003e\n\u003ctd\u003e3.370\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCenterline Radius\u003c\/td\u003e\n\u003ctd\u003e4.000\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLeg Length\u003c\/td\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003eTube OD Butt-Weld\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003ePolished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003e\u003cem\u003e\u003ca href=\"https:\/\/www.aceraceparts.com\/pages\/product-dimensions-mandrel-bends-tube-fittings\" target=\"_blank\" title=\"Ace Race Parts Mandrel Bend and Tube Fitting Dimensional Data\" rel=\"noopener noreferrer\"\u003eCLICK HERE\u003c\/a\u003e FOR MORE DETAILED MANDREL BEND DIMENSIONAL DATA.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003e\u003cspan\u003eWHAT IS 321 STAINLESS STEEL?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e321 Stainless Steel, like 304 Stainless Steel, is a low carbon, chromium nickel alloy with good intergranular corrosion resistance. 304 Stainless has good corrosion resistance up to 1,562°F (850°C); whereas, 321 Stainless allows for a higher temperature limit, including long term exposure to high temperatures, up to 1,652°F (900°C) due to the addition of Titanium, which acts as a stabilizer. 321 Stainless Steel's main advantage over 304 Stainless Steel in high temperature environments is that 321 Stainless offers better resistance to stress fractures. This higher resistance to stress fractures has advantages in automotive applications where differences in the Coefficient of Thermal Expansion (heat-related expansion and contraction which occurs at different rates) are greatest — typically between the engine and the manifold(s). 321 Stainless is better suited to handle this type of heat-related stress, as compared to 304 Stainless. While 304 Stainless is suitable for a wide variety of automotive applications, 321 Stainless is the superior choice for high temperature applications, and especially applications that see long term exposure to high temperatures like race cars, and offers a higher resistance to stress fractures and heat-related corrosion. For welding 321 Stainless Steel (including welding 321 Stainless to 304 Stainless) we recommend ER347 Filler Rod.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"line-height: 1.4;\"\u003e\u003cb\u003eWhat is Tube and How is it Different from Pipe?\u003cbr\u003e\u003c\/b\u003e\u003cbr\u003eTube size material is measured by the actual outside diameter (OD) and wall thickness.
