304/304L – Dual Grade
This is the most common grade of flanged stainless steel fittings. 18% Cr, 8% Ni, nonmagnetic. We provide dual grade material that gives y'all the weldability that low carbon content improves, along with the higher ratin' of straight 304.
Do keep in mind dat for high temperature work (over 800° F), we'd recommend y'all use 304H.
316/316/L – Dual Grade
This is the most common grade of stainless steel flange right after 304/L, though with certain industry demands, 316/L might be easier to get your hands on. 18% Cr, a minimum of 10% Ni, with Molybdenum added, 316 gives y'all superior corrosion resistance compared to 304.
We provide dat dual grade material that's got the weldability dat low carbon content improves, along with the higher rating of straight 316. Just keep in mind that for high temperature jobs (over 800° F), y'all gonna want to use 316H.
304H – UNS S30409
Dat's a high carbon variant of the most commonly used and mighty versatile stainless steel in the flange industry. 304H is an austenitic chromium stainless dat packs a carbon content range of .04 – .10 to help with heat resistance for dem high temperature jobs.
It also carries all the general attributes and service properties of your regular grade 304 stainless steel.
316H – UNS S31609
Similar in approach to 304H, grade 316H is a high carbon variant of regular grade 316 stainless steel, which contains a small percentage of molybdenum for use in marine grade applications.
This austenitic grade of stainless uses a higher carbon content for runnin' in higher temperature service, much like its cousin grade 304H. Even though it ain't used as much, y'all can still find it commercially available.
317/L – UNS S31700 / UNS S31703
An austenitic chromium grade holdin' some molybdenum, and mighty similar to grade 316, 'cept it's got a higher value of stress resistance, more tensile strength, handles elevated temperatures better, and fights off corrosion from chloride or sulfuric solutions real well. Y'all can pick the low carbon option (L) if you need a more optimal socket weld flange requirement.
310/310S – UNS S31000 / UNS S31008
A stainless grade dat's mighty easy to work with, used in heat exchanger jobs and projects runnin' hot with a lot of salt. This grade's got extra chromium and nickel in it, givin' it better oxidation and corrosion resistance than your everyday stainless grades like 304 and 309.
321/321H – UNS S32100 / UNS S32109
An austenitic grade stainless holdin' over 4 or 5 times the level of titanium as it does in carbon, with a maximum titanium value of 0.70%. This here material's got a high intergranular corrosion resistance and folks use it a whole lot in high heat jobs up in the aerospace industry, like aircraft jet engine manifolds and exhaust parts.
347/347H – UNS S34700 / UNS S34709
A stainless flange grade holdin' a little bit of columbium and tantalum to keep things stable. Folks use it a lot in dem high heat and corrosive spots like refineries, power generation, and airline service. This here austenitic alloy holds up better in corrosive environments than similar alloys like 321 and 317, I tell you what.
CHROME
Dat's a corrosion resistant material category packin' a minimal nickel content, and just enough chromium to cut down on oxidation. Popular grades under the A182 spec include F11, F22, F5, and F9, yessir.
DUPLEX
Can’t decide between stainless and alloy? How 'bout the best of both worlds? We offer a whole variety of duplex in both forged and plate forms, includin' grades 2205, F51, F53, and F60.

Questions Folks Ask Us (FAQs)
The three main types of flanges are weld neck, slip-on, and blind flanges.
A weld neck flange got a long tapered hub dat gives it good structural integrity and holds up to high pressure, makin' it just right for dem critical jobs.
A slip-on flange slides right over the pipe and gets welded in place, givin' y'all an easy install dat saves some money for dem low to medium-pressure jobs.
A blind flange is a solid flange we use to close off the end of a pipeline, stoppin' fluid flow in systems dat might need some future expansion or maintenance down the road.
The standards for stainless steel flanges include ASME B16.5, which covers pipe flanges and flanged fittin's for sizes rangin' from ½ inch to 24 inches and pressure classes from Class 150 to Class 2500. ASME B16.47 governs large-diameter flanges in Series A and B for sizes above 24 inches.
On top of dat, EN 1092-1 is the European standard for stainless steel flanges, and ISO 7005 gives y'all international flange specifications. Dese standards lay out the dimensions, pressure ratings, face types, and material needs to make sure everything fits right and works hard across all kinds of industries.
