304/304L – DUAL GRADE
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.
316/316/L – DUAL GRADE
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.
304H – UNS S30409
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.
317/L – UNS S31700 / UNS S31703
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.
310/310S – UNS S31000 / UNS S31008
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.
321/321H – UNS S32100 / UNS S32109
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.
