AL6XN Bars

Manufacturing Process Of AL6XN Bars


The first step in the process is melting raw materials in an electric furnace. These raw materials are typically iron ore, chromium, nickel, and other elements in exact amounts.


After melting, the metal is put into molds to form slabs or billets. The processing of these first forms is then continued.

Hot Rolling

After being heated, the billets are shaped into long, thin rods by going through a series of rolling mills. Because the metal is heated above its recrystallization temperature during this operation, it is known as hot rolling.


After that, the rods are annealed to reduce stress and enhance machinability. In order to do this, the rods must first be heated to a certain temperature and then gradually cooled.


Lastly, shearing machines or other cutting techniques are used to cut the rods to the required length.

What Are AL6XN Bars?

AL6XN bars refer to solid bars made from AL6XN alloy, a high-performance austenitic stainless steel primarily composed of nickel, chromium, molybdenum, and nitrogen. AL6XN offers exceptional corrosion resistance in aggressive environments such as chloride-containing solutions, making it suitable for applications in chemical processing, marine engineering, and pharmaceutical industries. AL6XN bars are known for their excellent strength, durability, and resistance to pitting and crevice corrosion, making them ideal for demanding industrial applications.

AL6XN Bars of Specifications and Sizes

AL6XN stainless steel bars have long been recognized for their exceptional corrosion resistance when exposed to aggressive environments like acidic chloride solutions, where corrosion protection can often prove essential. AL6XN bars typically conform to ASTM standards such as ASTM A276 for general requirements and ASTM A479 for stainless steel bars and shapes, including common sizes ranging from 1/4" diameter up to 12", depending on customer specifications or industry regulations. AL6XN bars exhibit exceptional tensile strength and excellent weldability, making them suitable for chemical processing applications in marine environments and other demanding conditions where corrosion resistance is essential. AL6XN bars may undergo heat treatment processes in order to enhance mechanical properties further enhance corrosion resistance.
