We has experience pouring a wide variety of stainless steel alloy casts. We cast stainless steel from miniature to 50 pounds.

The most common alloys we have poured are listed below. We are also capable of pouring other air melt alloys upon your request. Specific material chemistry and mechanical specifications will be provided to you if needed. For your Stainless Steel Castings needs, we can help you out.


Commonly Cast Stainless Steel Alloys:

Stainless Steel 304(1.4308)

This is the most common stainless steel and is applied in different applications. It consists of at least 18% chromium and 8% nickel and has no magnetic properties within its austenitic structure.

Stainless Steel 304L(1.4309)

Corresponds to stainless steel 304. The ‘L’ stands for ‘low carbon’, so this stainless steel has a lower carbon amount to increase weldability and to limit the corrosion sensitivity after welding.

Stainless Steel 316(1.4408)

A better, but more expensive type of corrosion resistant steel is stainless steel 316. This alloy contains at least 16% chromium, 10% nickel and 2% molybdenum. Because of the addition of molybdenum, this stainless steel type is better defended against salt corrosion and acids, and is often applied in chemical industries.

Stainless Steel 316L(1.4409)

Comparable to stainless steel 316 but with a lower carbon level to increase weldability of the stainless steel.

17-4 PH(1.4549)

A high quality stainless steel which is regularly used in the aircraft industry. It is characterized by a high tensile strength, hardness, toughness and is also corrosion resistant.



304 Stainless Steel versus 316 Stainless Steel

Corrosion resistance of stainless steel varies by grade


Judging by the name, you might assume that stainless steel never stains—but you’d be wrong.

Stainless steel stains less easily than other iron-based metals, but it’s not literally “stainless”. Just like standard steel, stainless can get marked up by fingerprints and grease, develop discoloration, and eventually rust. The difference is resilience. Stainless steel can withstand much more time and abuse before showing signs of wear.

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium—the alloy that gives stainless steel its famous corrosion resistance.

And this is where things get complicated. There are multiple grades under the stainless steel umbrella, each with slightly different alloy composition, and therefore slightly different physical characteristics.

Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous and selenium.

The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 doesn’t.

For outdoor furnishings like rails and bollards, stainless steel is an ideal corrosion-resistant material, but it will only withstand long-term exposure if the grade is appropriate for its environment. 304 is an economical and practical choice for most environments, but it doesn’t have the chloride resistance of 316. The slightly higher price point of 316 is well worth it in areas with high chloride exposure, especially the coast and heavily salted roadways. Each application for stainless steel has its own unique demands, and needs a stainless steel that’s up to the task.


Natural corrosion resistance

Corrosion is a natural phenomenon. Pure elements always react with the surrounding environment, which is why so few elements are naturally found in their pure form. Iron is no exception.

In wet or humid conditions iron reacts with the oxygen contained in water to form iron oxide, also known as rust. The red flaky oxide deteriorates easily—exposing more material to corrosion. Iron and standard carbon steels are highly susceptible to this type of corrosion.

Stainless steel has the innate ability to form a passive layer that prevents corrosion. The secret?

Chromium.

The chromium found in all stainless steels reacts quickly with oxygen environments, much the same as iron. The difference, however, is that only a very fine layer of chromium will oxidize (often only a few molecules in thickness). Unlike flaky and unstable iron oxide, chromium oxide is highly durable and non-reactive. It adheres to stainless steel surfaces and won't transfer or react further with other materials. It is also self-renewing—if it’s removed or damaged, more chromium will react with oxygen to replenish the barrier. The higher the chromium content, the faster the barrier repairs itself.

Once oxidized, or passivized, stainless steel typically rusts at a very low rate of less than 0.002 inches per year. When kept in its best condition, stainless steel offers clean and bright surfaces ideal for many building and landscape designs.


304 Stainless Steel

304 stainless steel is the most common form of stainless steel used around the world, largely due to its excellent corrosion resistance and value. It contains between 16 and 24 percent chromium and up to 35 percent nickel, as well as small amounts of carbon and manganese.

The most common form of 304 stainless steel is 18-8, or 18/8, stainless steel, which contains 18 percent chromium and 8 percent nickel.

304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications. It is also common in buildings, décor, and site furnishings.

304 stainless steel does have one weakness: it is susceptible to corrosion from chloride solutions, or from saline environments like the coast. Chloride ions can create localized areas of corrosion, called "pitting," which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.


316 Stainless Steel

316 grade is the second-most common form of stainless steel. It has almost the same physical and mechanical properties as 304 stainless steel, and contains a similar material make-up. The key difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum. The addition increases corrosion resistance, particularly against chlorides and other industrial solvents.

316 stainless steel is commonly used in many industrial applications involving processing chemicals, as well as high-saline environments such as coastal regions and outdoor areas where de-icing salts are common. Due to its non-reactive qualities, 316 stainless steel is also used in the manufacture of medical surgical instruments.

Alternative 300-series grades can contain up to 7 percent molybdenum. They provide even better chloride resistance, but such heavy-duty resistance is only necessary in industrial or high concentration exposure conditions.


Versatile applications

Both 304 and 316 stainless steels (as well as other 300-series grades) use nickel to maintain an austenitic composition at lower temperatures. Austenitic steels ensure a versatile balance of strength, workability, and corrosion resistance, making them ideal for outdoor architectural features, surgical instrumentation, and food processing equipment.

A large volume of stainless steel produced today (especially 316 stainless steel) can be found in products related to the food and beverage industries. Stainless steel is commonly found in commercial kitchens and food processing plants as it serves a variety of needs:

It can be easily formed and fabricated into shapes needed to produce a variety of equipment and machinery, such as cooking tables, ventilation hoods, tanks, and hoppers.

It is available in a wide range of decorative and polished finishes.

It can withstand shock and abrasive conditions found in kitchens or food processing plants.

It can be easily cleaned, and can withstand repeated washing with the many chemicals and detergents employed to meet public health demands.

It does not react to the alkalis and acids found in milk, cooked foods, vegetables, and food additives.

The ultimate benefits of stainless steel include a long service life that will retain an attractive, clean finish. Properly cared for and cleaned stainless steels present a low maintenance cost
