Basics: Stainless Steel Castings
Have you ever thought about the unsung hero in your kitchen, the trusty pots and pans that have seen countless meals through thick and thin? Or maybe you've appreciated that sturdy workbench in your shop, the silent base supporting your projects. If not, you're probably perfectly normal, but chances are you've been rubbing elbows with stainless steel more often than you realize! From the gleaming utensils you cook with to sterile medical equipment at the dentist or doctor's office, stainless steel quietly plays a role in our daily lives.
Today's blog is the latest installment in our "In the Field" series, where we explore the benefits that certain alloys afford your design project and usage scenarios across several industries. The star of today's show? Stainless steel!
Stainless steel is a popular casting material because it boasts both utilitarian and aesthetic appeal.
Why Use Stainless Steel?
Stainless steel is a lot more than a pretty, shiny face in your kitchen; it's a showstopping material that combines strength, esthetics, durability, and more. Here are just a few of its stand-out features:
1) Corrosion Resistance:
Stainless steel is corrosion-resistant and an expert at surviving in extreme environments. Stainless steel is an alloy composed of steel, a minimum of 10.5% chromium, and quite frequently nickel or carbon. Once combined, these elements can resist rust and corrosion in open air, underwater, chlorine-rich environments, and even in acidic or alkaline solutions.
Fascinatingly, the chromium in stainless steel allows it to "self-heal" when exposed to oxygen. This means next-level longevity out of your metal components with very little upkeep.
Whether it's the exposed elements of outdoor structures like the Gateway Arch (1.) or precision instruments in a medical setting, its ability to withstand the effects of moisture makes it an excellent choice for any product that needs to stand the test of time.
2) Super Strength:
Beyond its polished exterior lies stainless steel's robust strength, offering your parts unparalleled durability and reliability. Stainless steel has some of the most tensile strength you'll find in metalworking. From automotive components to structural elements in construction, this material's high strength and frequent use is a testament to its ability to endure and thrive under the most demanding conditions.
3) Temperature Resistance:
A foundry can cast stainless steel in various grades that equip it to navigate the extremes of temperature easily. Applications ranging from industrial machinery or aerospace components in high-temperature environments to cryogenic equipment benefit from stainless steel's ability to maintain structural integrity across a broad thermal spectrum.
4) Hygenic & Easy to Clean:
In industries where hygiene is imperative, stainless steel emerges as a material of choice, characterized by its smooth, non-porous surface. This feature not only facilitates easy cleaning but also ensures that medical instruments and food processing equipment maintain impeccable standards of cleanliness, free from microbial threats.
5) Sleek Aesthetics:
Beyond its purely utilitarian features, stainless steel introduces a touch of sophistication to design. The reflective surface and modern aesthetic make it a preferred choice in architectural applications and sleek consumer products. But it is more than just a sexy metal; when coupled with its capabilities, you have an alloy built to perform and look good doing it.
6) Chemical Guardian:
In environments where chemical resilience is paramount, stainless steel is an indispensable guardian. Its resistance to a wide array of chemicals makes it an essential material in chemical processing, petrochemicals, and pharmaceuticals, where exposure to corrosive substances is a constant consideration.
7) Recyclability:
At the end of its lifecycle, stainless steel is almost 100% recyclable, and its high value actively encourages reuse. According to The Nickel Institute, "the amount of stainless steel scrap currently being used reduces the energy required for stainless steel manufacture by around one-third" compared to virgin materials.

Stainless steel's non-reactive nature and ease of sterilization make it a preferred material for medical instruments and equipment. Its use in surgical tools and equipment supports stringent hygiene standards in medical environments. Furthermore, its heat resistance allows soiled instruments to be cleaned in autoclaves without losing structural integrity.
Chemical Processing:
Stainless steel is resistant to various chemicals, making it suitable for vessels, reactors, and pipes in chemical processing plants. Its corrosion resistance ensures the safety and longevity of equipment in chemical manufacturing.
Food and Beverage:
Stainless steel's smooth surface and resistance to bacteria make it an excellent choice for food processing equipment and storage tanks. It meets strict hygiene standards in food production, ensuring the quality and safety of consumables.
Stainless steel is used in professional and home kitchens throughout the world. Its easy-to-clean nature, durability, and good looks will keep it a mainstay for years to come.
Marine Industry:
Stainless steel casting is widely used in marine applications due to its ability to withstand the corrosive effects of saltwater. From ship components to offshore structures, stainless steel ensures longevity in maritime environments.
Construction Industry:
Stainless steel's aesthetic appeal, strength, and corrosion resistance make it suitable for architectural elements, art installations, structural components, and facades. It combines form and function in construction, contributing to buildings' durability and visual appeal.
Power Generation:
Stainless steel is used in power plants for components exposed to high temperatures, such as turbine parts and exhaust systems. Its heat-resistant properties contribute to the efficiency and reliability of power generation equipment.
Water Treatment Industry:
Stainless steel is commonly used for pipes, valves, and fittings in water treatment plants due to its corrosion resistance. It ensures the integrity of water treatment infrastructure and withstands the corrosive nature of water treatment processes.
Renewable Energy Industry:
Stainless steel is utilized in components for renewable energy systems, such as wind turbines and solar panels, due to its corrosion resistance and strength. In renewable energy applications, stainless steel ensures the longevity and efficiency of components exposed to various environmental conditions.
