Specialty Stainless Solutions

Solutions

Today, Crompion International offers multiple grades of Cromgard Stainless Steel that deliver solutions to a range of challenges. Below is a list of special features each member of the Cromgard family of stainless steels provides. However, for more specific, technical information about our new Cromgard grades visit the Product section of our site, or call one of our technical team members.

By using Cromgard we have been able to tremendously cut down our long-term costs and maintenance. It’s also much more economical than traditional stainless steel. Plus, it doesn’t fluctuate in price, so this allows us to budget each year and slowly switch to Cromgard where it is most needed. We’re using it throughout the plant.

Cromgard C12

At 12-percent Chromium, it offers high strength and long-term durability. It is 85% stronger than 304L SS*, and stronger and more corrosion resistant than aluminum. It is up to 250 times more corrosion resistant than uncoated mild steel and is an economical substitute for conventional stainless steel where mild corrosive conditions do not justify use of expensive 18/8 grades. Cromgard C12’s excellent strength properties also provide the opportunity to reduce weight in structural applications.  *(for thicknesses <8mm)

Cromgard C18-1

At 18-percent chromium, it provides excellent corrosion resistance in moderately corrosive environments and good oxidation resistance at elevated temperatures. This steel is targeted to replace early-grade 400-series where higher temperatures and corrosion resistance is required. It is very suitable for automotive exhaust systems.

Cromgard C18-4

At 18-percent chromium, it shows good pitting  and crevice corrosion resistance, similar to grades 309, 310, 316 and 316L stainless steels , and better than grades 201, 201L, 304, 304L and 321 stainless steels. Suitable  for roofing and cladding in marine environments, as well as hot water tanks, heat exchanger tubing and food processing equipment. 

Cromgard C20-1

At 20-percent chromium, it has similar general, pitting and crevice corrosion resistance to 201, 201L, 304 and 304L stainless steels.   However , this  is dependent on the corrosion media. For example, Cromgard C20-1 has significantly better corrosion resistance than 316L in sulphuric acid (H2SO4) solutions. The atmospheric corrosion resistance of Cromgard C20-1 is unequalled by virtually all other uncoated engineering materials and it is normally sufficient in urban and industrial environments. The  excellent strength, toughness, corrosion resistance and resistance to stress corrosion cracking (SCC) make Cromgard C20-1 suitable for applications such as process and storage tanks, some food and beverage applications as well as several structural applications.

Cromgard C20-3

Cromgard C20-3: At 19.5-21.5-percent chromium, its yield strength is more than double that of austenitic stainless steels such as grades 304L and 316L. This often allows down gauging in the design, depending on Young’s Modulus and buckling limitations. Cromgard C20-3 has similar general and pitting corrosion resistance that fills the gap between Type 316L austenitic stainless steel and DSS grade 2205. Its excellent strength, toughness, corrosion resistance and resistance to stress corrosion cracking (SCC) make Cromgard C20-3 suitable for a wide range of applications such as: subsea flow lines, bridge decking, desalinization, water heaters, pipes & tubes, water treatment, potable water systems, power generation, chemical processing, transport tanks, home appliances. heat exchangers, pressure vessels, architectural structures and pulp & paper production.

Cromgard C21

At 20.5-23.5-percent chromium, it has better corrosion resistance than Type 304L in most applications and performs as well as Type 316L in many environments while at the same time having the higher strength characteristics of duplex stainless steels. The yield strength of Cromgard C21 is more than double that of austenitic stainless steels such as grades 304L and 316L. This strength advantage often allows down gauging in the design, depending on Young’s Modulus and buckling limitations. Cromgard C21’s excellent strength, toughness, corrosion resistance and resistance to stress corrosion cracking (SCC) make it suitable for applications such as: subsea oil & gas, top side oil & gas, pipes & tubes, storage tanks, power generation, transport tanks, heat exchangers, cosmetic architectural and structural architectural.

Cromgard C23

Offers similar general and pitting corrosion resistance to the grade 316L stainless steel and its atmospheric corrosion resistance is unequalled by virtually all other uncoated engineering materials.  Its excellent strength, toughness, corrosion resistance and resistance to stress corrosion cracking (SCC) make Cromgard C23 suitable for applications such as process and storage tanks, food and beverage applications as well as several structural applications. Cromgard C23 should be used in applications that require better corrosion resistance, such as environments containing chlorides and polluted marine environments, desalinization plants, etc.
