Corrosion resistant stainless steel flanges as the superior commodity choice.
This is the most common grade of stainless steel. 18% Cr, 8% Ni, nonmagnetic. We provide dual grade material that has the weldability that low carbon content improves as well as the higher rating of straight 304. Do note that in high temperature applications (over 800degF), 304H would be recommended.
This is the most common grade of stainless steel after 304/L, though due to certain industry demands, 316/L may more readily available. 18% Cr, a minimum of 10% Ni, with Molybdenum added, 316 provides superior corrosion resistance compared to 304. We provide dual grade material that has the weldability that low carbon content improves as well as the higher rating of straight 316. Do note that in high temperature applications (over 800degF), 316H would be recommended.
A high carbon variant of the most commonly used and extremely versatile stainless steel in the flange industry. 304H is an austenitic chromium stainless which contains a carbon content range of .04 – .10 to help with heat resistance for high temperature applications. It also carries all the general attributes and service properties of regular grade 304 stainless steel.
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 utilizes a higher carbon content for use in higher temperature service, much like its cousin grade 304H. Though it is less commonly used, it is still commercially available.
An austenitic chromium grade containing molybdenum, and similar to grade 316, except with a higher value of stress resistance, increased tensile strength, higher service in elevated temperature, and general resistance to corrosion from chloride, sulfuric solutions, or other corrosive media. The low carbon option (L) can be selected for a more optimal weld requirement.
A stainless grade with excellent workability, utilized in heat exchanger applications and projects with elevated temperatures involving high salinity. This grade contains an increased chromium and nickel content and has elevated characteristics of oxidation and corrosion resistance when compared to more common stainless grades such as 304 and 309.
An austenitic grade stainless containing over 4 or 5 times the level of titanium as it does in carbon, with a maximum titanium value of 0.70%. This material has a high intergranular corrosion resistance and is well utilized in high heat applications in the aerospace industry such as aircraft jet engine manifolds and exhaust components.
A stainless grade containing a small percentage of columbium and tantalum for stabilization purposes. Commonly used in the combined high heat and corrosion environments of refineries, power generation, and airline service, this austenitic alloy retains better properties in corrosive environments compared to similar alloys 321 and 317.
A corrosion resistant material category containing a minimal nickel content, and just enough chromium to reduce oxidation. Popular grades under the A182 spec include F11, F22, F5, and F9.
Can’t decide between stainless and alloy? How about the best of both worlds? We offer a variety of duplex in both forged and plate forms including grades 2205, F51, F53, and F60.
