MAXCORE / SPECIAL ALLOYS
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 NEUMO Ehrenberg Group offers MaxCore alloy tube and fittings manufactured in strict compliance with the ASME-BPE Standard and is offers benefitting in improved corrosion resistance for the most aggressive environments 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 passive 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.
Some of the common applications for the MaxCore special alloy 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
SUPERAUSTENITIC MaxCore 6MO (UNS N08367)
This superaustenitic 6% Molybdenum containing material 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.
SUPERAUSTENITIC MaxCore 904L (UNS N08904)
This superaustenitic 4% Molybdenum containing material is more commonplace for usage in Europe and is designed for moderate corrosion resistant applications. 904L is a good alternative for usage where Duplex steels have been determined as a successful material of construction. Higher molybdenum helps resistance to pitting for applications just above the 316L austenitic threshold and below the 6'' molybdenum application.
Nickel alloy MaxCore Alloy 22 (UNS N06022)
Alloy 22 is a high nickel-chromium-molybdenum alloy with good resistance to both uniform and localized corrosion. With resistance to a wide variety of chemicals, Alloy 22 is an excellent choice where upset conditions may occur. With a strong resistance to chlorides, Alloy 22 is an excellent choice for both brine and buffer solutions. Alloy 22 also resis the formation of grain boundary precipitation in the heat affected zones and thusly can be used in the as-welded conditions without concern of over-alloying weld joins.
