When you need a material with superior corrosion resistance that can be subjected to high temperatures without losing its structural integrity—and when you want the best steel for a wide range of sensitive applications—consider stainless steel fabrication services by Boardman. Stainless steel fabrication is preferred when oxidation could be problematic, when a more durable metal than carbon steel is needed, or when a lower-cost option than titanium is required. Let’s discuss your stainless-steel project now.
Stainless steel is often chosen for its corrosion-resistant properties. It’s able to withstand even the harshest of environments–like those found in the oil & gas industry. Highly-corrosive compounds like chlorides, sulphur, ammonia, sulfuric acid, naphthenic acid, polythionic acid, hydrogen, carbon dioxide, cyanides, hydrogen chloride, phenols, and oxygen can wreak havoc on other types of metal. That what makes stainless steel so valuable in industries where these compounds–and those like them–are present.
Some examples? Austenitic stainless steel is used in corrosive environments and high temperatures. Duplex performs well when superior strength and corrosion resistance can’t be compromised. Contact us to discuss what’s possible.
Have you ever contracted with a fabricator only to discover they don’t have the capabilities to deliver what they promised? Or have you found out they had to farm out part of the job to cover for their lack of know-how?
That won’t happen when you partner with Boardman. Since 1910, we’ve been fabricating stainless steel pressure vessels for many industries in a wide range of dimensions. From a 24”OD x 8’ Acid Gas Knockout Drum constructed of SA-240-316L material to a 108”ID x 84”ID x 130’ Demethanizer Tower constructed of SA-240-304L material, we’ve got whatever you need covered.
Here are more examples of stainless-steel projects you’ll see coming out of Boardman’s 140,000 ft² Oklahoma City facility:
When you choose a fabricator who has the capability to work with all these metals, you can forget about shopping around:
We invite you to view a few of our past projects for yourself, some of which have been fabricated with stainless steel. You’ll find that our services include heavy plate fabrication, custom fabrication, trayed towers and columns, and ASME pressure vessels. Then give us a call to see how we can help you.
We have experience fabricating equipment from 310, 321, 347, 304, 316, 410, & 317, for projects in cryogenic, gas processing, chemical, and petrochemical industries.
All our welding procedures are qualified to meet ASME Section IX and ASME Section VIII standards. Our fabrication welding processes consist of SAW, FCAW, SMAW, GTAW, GMAW, and ESW for Corrosion Resistant Overlay (CRO).
We always welcome questions about our capabilities, and we look forward to speaking to you soon.
Not all stainless steel is alike. Each grade comes with its own price point and benefits.
This is the most widely produced austenitic stainless steel. It resists corrosion in moderately reducing and moderately oxidizing environments. 304L can match the mechanical properties of 304 with the controlled introduction of nitrogen, explaining why many products can be certified as 304/304L.
For chemical-processing applications, this is the most commonly prescribed grade of stainless steel. Molybdenum increases its resistance to corrosion, chloride pitting, and strength in high-temp situations. With controlled nitrogen addition, 316/316L can maintain low-carbon content and match the mechanical properties of straight-grade 316.
For heat and oxidation resistance up to 1900°F under contact temperatures and up to 1850°F with frequent thermal cycling, 309 stainless is an austenitic alloy with high chromium and low (relatively) nickel content often prescribed for sulfur-bearing, high-temperature applications. Its resistance to carbon absorption can be categorized as ‘moderate’ and, therefore, is not recommended for highly carburizing atmospheres.
When service temperatures are in the 1000°-1600°F range, this titanium-stabilized grade of stainless steel may be used. For service temps up to 1600°F, an air-cool stabilizing treatment is administered 1550°-1650°F for optimum intergranular corrosion resistance and polythionic acid stress corrosion cracking resistance.
For applications where temperatures will reach 1500°F, this 0.04% minimum carbon type of 304 stainless steel with corrosion resistance comparable to low-carbon, dual-certified 304/304L is used. Carbide precipitation can be a problem in the weld heat-affected zone. Weldments can be sensitive to polythionic acid stress corrosion cracking and HAZ intergranular corrosion in environments with oxidizing acid. When high-temp mechanical properties are necessary, carbide precipitation is not harmful.
For enhanced corrosion resistance (when compared to 304/304L and 316/316L), this molybdenum / austenitic stainless steel contains elevated levels of molybdenum, nickel, and chromium (more than 316L). It has expanded resistance to general corrosion and chloride pitting. 317L can meet 317’s mechanical properties while maintaining low carbon content with controlled nitrogen addition.
For applications in strong oxidizing environments, 347 stainless delivers corrosion resistance greater than 321. Stabilized with columbium, which improves its resistance to intergranular attack, it’s preferred in low-temperature (up to 1500°F) and aqueous environments, although its high-temp oxidation resistance is similar to 304. For decent resistance to oil refinery polythionic acid stress corrosion cracking, either 347 or 321 may be used.
This is a low-carbon 410 modification (with the option of a small titanium and/or columbium addition to minimize high-temp austenite formation) that’s ferromagnetic and entirely ferritic in the annealed condition. It remains ductile and soft even when rapidly cooled from above the critical temperature. This aids in crack prevention while welding or during exposure to high temps.
