6mm Stainless Steel Round Bar DIN1.4501 ASME B690 Al-6XN Corrosion-Resistant Superalloys
Al-6XN/ UNS N08367 Round Bar DIN1.4501 ASME B690 Al-6XN Material CORROSION-RESISTANT SUPERALLOYS
AL-6XN® alloy solves many tough corrosion problems facilities face. The experts at Central States Industrial (CSI) take corrosion seriously and understand that waiting months for tubing, fittings, and equipment is never a feasible option. CSI carries an extensive stock of corrosion resistant superalloys, allowing for a quick turnaround.
The high strength and corrosion resistance of the AL-6XN alloy make it a better choice than other superaustenitic stainless steels, such as 254 SMO® or 904L. It outperforms conventional duplex stainless steels—such as 2205 or 2507—and is a cost-effective alternative to more expensive nickel-based alloys in applications where excellent formability, weldability, strength, and corrosion resistance are essential.
AL-6XN alloy has both the strength and the corrosion resistance to maximize life cycles.
ABOUT AL-6XN ALLOY
AL-6XN alloy has exceptional resistance to chloride corrosion, pitting, crevice corrosion, and stress corrosion cracking. It has excellent corrosion resistance to various acids, alkalis, and salt solutions.
AL-6XN alloy is identified by the Unified Numbering System (UNS) designation of N08367. It is an austenitic stainless steel alloy with high nickel (24%), chromium (22%), molybdenum (6%), and nitrogen (0.18%) content and is commonly known as superaustenitic stainless steel (alloys such as 254 SMO and 904L also fall under the superaustenitic designation). AL-6XN alloy has a face-centered cubic crystal structure similar to other austenitic stainless steels such as 304L and 316L. The alloy is non-magnetic, and its magnetic permeability remains low even after severe cold forming.
AL-6XN (UNS designation N08367) is a type of weldable stainless steel that consist of an alloy of nickel (24%), chromium (22%) and molybdenum (6.3%) with other trace elements such as nitrogen.
The high nickel and molybdenum contents of the AL-6XN alloy give it good resistance to chloride stress-corrosion cracking. The molybdenum confers resistance to chloride pitting. The nitrogen content serves to further increase pitting resistance and also gives it higher strength than typical 300 series austenitic stainless steels, and thereby often allows it to be used in thinner sections.[1]
This metal is commonly used in lieu of 300 series stainless steels in high temperature and low pH applications in food processing. For example, tomato juice will corrode 316L stainless steel at pasteurization temperatures of 210 °F (100 °C). AL-6XN will better resist this corrosion while still offering the beneficial properties of stainless steel.
