  MaxCore 6Mo

  MaxCore 904L

  MaxCore Alloy 22



Why Special Alloys?

While 316L is adequate for most applications, high chloride media, acidic pH levels, high temperature, time of contact, and equipment design can affect the corrosion of stainless steel.

The MaxCorealloy family, offerd by the NEUMO Ehrenberg Group contains a wide range of special alloys: 904L, 6Mo (Ultra 6XN®, AL-6XN®) ,  Alloy 22 (C22® ,Hastelloy® )

These alloys are commonly used in the biotech, pharmaceutical, personal care, home care, food, dairy, and beverage industries worldwide.


The Value of proper material selection

Increase Production - Decrease downtime and product loss

No Maintenance Cost - Eliminate regular replacement and repair of failed material

No Microbial Contamination - No crevice and pitting corrosion, no product buildup

One-time Material Investment - Proper material compatibility equals to a long running equipment

Stainless Steel and Corrosion

The uniqueness behind the corrosion resistance of stainless steel is the formation of a durable and spontaneous ultra-thin film that covers the surface.

The resistance of this film is dependent on the steel grade chosen and the conditions to which it is exposed. If the conditions become aggressive, the oxide film breaks down resulting in corrosion.

The main types of corrosion affecting hygienic and high purity application in aggressive chloride environments are pitting, crevice, and stress corrosion.

Optimum performance is obtained by the use of alloying elements; chromium, molybdenum, nickel, and nitrogen.


Typical Applications

Some of the common applications for the special alloys; 904L, 6Mo and Alloy C22 in the hygienic, biotech and pharmaceutical industries.

  • Biotech and Pharmaceutical - buffer solutions, chromatography lines, API, ethanol distillation, saline solutions
  • Personal care - shampoo, conditioner, toothpaste, deodorant/antiperspirant, body wash, liquid soap
  • Home care - fabric softener, detergent, cleaners
  • Food, dairy and beverage - ketchup, tomato sauce, mayonnaise, soy sauce, barbecue sauce, chili sauce, breaker eggs/liquid eggs, soup, brine solutions, cheese, isotonic drinks


The superaustenitic also known as high-performance stainless steel share many characteristics with its standard grade counterpart like high tensile strength, good weldability, and formability becoming a better choice than duplex stainless steel. Additionally, it is a cost-effective alternative to more expensive nickel-base alloys.

Our Offering:

MaxCore 904L - UNS N08904

MaxCore 6Mo - UNS N08367 (AL-6XN®; Ultra 6XN)

MaxCore Alloy 22 - UNS N06022


Nickel-based alloy

Alloy 22 is a nickel-chromium-molybdenum alloy with enhanced resistance to corrosion. The alloy provides exceptional resistance to pitting and crevice corrosion attacks in chloride-induced media as well as stress corrosion cracking.
