Flanges made of corrosion-resistant stainless steel are the best option for this type of item.
304/304L – DUAL GRADE
This particular grade of stainless steel is the one that is most widely used. 18% Cr, 8% Ni, nonmagnetic. We offer dual grade material, which not only has the higher rating of straight 304 but also benefits from the improved weldability that low carbon content brings about. Please take note that the suggested material for use in environments with temperatures more than 800 degrees Fahrenheit is 304H.
316/316/L – DUAL GRADE
After 304/L, this is the most prevalent grade of stainless steel, while 316/L may be more easily available due to the demands of particular industries. When compared to 304, the corrosion resistance offered by 316, which contains 18% Cr, a minimum of 10% Ni, and an addition of Molybdenum, is significantly higher. We offer dual grade material, which not only has the better rating of straight 316 but also benefits from the improved weldability that low carbon content brings about. Be aware that 316H is the recommended material for use in environments with temperatures more than 800 degrees Fahrenheit.
304H – UNS S30409
A high-carbon form of the stainless steel that is the industry standard for flanges and is capable of an exceedingly wide range of applications. The austenitic chromium stainless 304H has a carbon content that ranges from.04 to.10 percent, which contributes to its heat resistance and makes it suitable for use in high-temperature applications. In addition to this, it possesses all of the general characteristics as well as the service properties of standard grade 304 stainless steel.
316H - UNS S31609
The 316H grade of stainless steel is a high-carbon variation of the ordinary 316 grade of stainless steel. It also contains a tiny proportion of molybdenum for use in marine grade applications. The 304H grade of stainless steel is approached in a similar manner. This austenitic grade of stainless steel, like its close relative grade 304H, makes use of a larger carbon content so that it can be used in services that involve higher temperatures. Although it is not used as frequently as it once was, it is still available for purchase in the market.
317/L-UNS S31700 / S31703
An austenitic chromium grade that contains molybdenum. This grade is very similar to grade 316, with the exception that it has a higher value of stress resistance, increased tensile strength, greater service in elevated temperature, and general resistance to corrosion from chloride, sulfuric solutions, or other corrosive media. In order to achieve superior results with the welding process, you may choose the low carbon option (L).
310/310S - UNS S31000 / UNS S31008
A stainless grade that possesses great workability and is used in applications involving heat exchangers as well as projects involving extreme temperatures and high salinity. In comparison to other, more popular types of stainless steel, such as 304 and 309, this grade of stainless steel has a higher concentration of chromium and nickel, as well as enhanced resistance to oxidation and corrosion.
321/321H - UNS S32100 / UNS S32109
A type of austenitic stainless steel that has a maximum titanium content of 0.70% and contains four or five times as much titanium as it does carbon. This material has a strong intergranular corrosion resistance and is widely used in high heat applications in the aerospace sector. Some examples of these applications are exhaust components and aircraft jet engine manifolds.
347/347H – UNS S34700 / UNS S34709
A variety of stainless steel that has been stabilized through the addition of a minute quantity of columbium and tantalum. This austenitic alloy retains greater qualities in corrosive conditions compared to related alloys 321 and 317, and as a result, it is frequently employed in settings that involve both high heat and corrosion, such as those found in refineries, power generating, and aircraft operations.
CHROME
A type of materials that are resistant to corrosion and include only a trace amount of nickel and just the right amount of chromium to prevent oxidation. The grades F11, F22, F5, and F9 are all quite popular within the A182 specification.
DUPLEX
Are you having trouble choosing between stainless and alloy? What about getting the advantages of both situations? We have several grades of duplex available, some of which are 2205, F51, F53, and F60. These grades are available in both forged and plate forms.
