Manufacturing Process Of AL6XN Coils

Reheating Furnace

Reheating furnaces are used in hot rolling mills to heat the steel stock to the rolling temperatures.

Scale Breaker

Slab moves first through a scale breaker, which is a two-high rolling mill with vertical rolls that loosens the furnace scale and removes it with high-pressure water jets.

Finish Rolling

The last stage of the rolling process is cold rolling,


Cooling or Quenching is a process of cooling a metal at a rapid rate.

Skin Pass Mill

This produces high-gloss surfaces and achieves the desired mechanical strip properties such as deep-drawing strength.

Marking & Packing

Proper packaging and labeling not only makes the final product look attractive but also save a huge amount of money by saving the product from wrong handling.

What are AL6XN Coils?

AL6XN is a high-performance austenitic stainless steel alloy known for its exceptional corrosion resistance in aggressive environments. AL6XN coils are typically used in applications requiring resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. They offer superior strength and durability, making them suitable for applications in industries such as chemical processing, marine, and offshore oil and gas. AL6XN coils are often utilized in heat exchangers, tubing, and piping systems where corrosion resistance is paramount.

Equivalent Grade for AL6XN Coils

AL6XN coils are high-performance austenitic stainless steel alloys designed with exceptional corrosion-resistance in harsh environments like seawater and acidic solutions, featuring excellent resistance properties against corrosion. AL6XN stands up well against chloride pitting, crevice corrosion and stress corrosion cracking when compared with conventional stainless steels. When considering equivalent grades for comparison purposes, AL6XN compares favorably with Alloy 904L or duplex stainless steel 2205 alloys. AL6XN often outshines its counterparts under extreme conditions due to its special composition - an amalgamation of high levels of chromium, molybdenum and nitrogen. With strength, corrosion resistance and weldability properties to match, AL6XN makes an excellent choice for use across many industrial fields from chemical processing, paper production and marine engineering to chemical processing plants and chemical refineries.

Chemical Composition of AL6XN Coils

AL-6XN is a super austenitic stainless steel known for its exceptional corrosion resistance in aggressive environments. Its chemical composition typically includes nickel (24-26%), chromium (20-22%), molybdenum (6-7%), nitrogen (0.18-0.25%), and iron (balance). Additionally, it contains small amounts of copper (0.75-1.50%) and nitrogen (0.15-0.25%). This composition provides AL-6XN with high strength and resistance to pitting, crevice corrosion, and chloride stress corrosion cracking.
