It is important to choose the right material for any application, particularly the one designed for corrosion resistance, wash-down, strength, or heat resistance. There is an array of materials for you to pick from with numerous specifications attached to those. Stainless steel (SS) is a well-known and affordable option in many industries, including the construction sector. Here, as one of the best steel fabrication and engineering companies in UAE, we will discuss SS types, their properties and benefits.
Stainless Steel Alloy Types
The words austenitic, duplex, martensitic and ferritic refer to the main SS alloy types. Here, in our capacity of being one of the preeminent steel fabrication and engineering companies in UAE, we will talk about those types.
Austenitic SS is more popular and widely used as compared to the others. A non-magnetic material, it has a structure that makes hardening the material possible for a structural steel fabricator in UAE or elsewhere. Here, we will look at the 304 grade austenitic SS subgroup since it is more broadly used than other grades.
A material low in carbon, 304-grade stainless steel contains 8% nickel and 18% chromium at the least. Therefore, it is also known as 18/8 steel. The material is resistant to corrosion and oxidation, so its use is common for commercial and household equipment manufacturing and building construction. This durability can ease the fabrication process for a steel fabricator in UAE or elsewhere as well as can prevent product contamination. It is regarded as the most common and versatile austenitic SS and a more effective option in terms of cost than 316-grade stainless steel.
Duplex SS is highly corrosion resistant and hardenable. The microstructures of the material comprise a combination of ferrite and austenite phases. Consequently, duplex SS displays properties typical of ferritic and austenitic stainless-steel varieties. One of the best features of the material is its strength. It is relatively stronger than ferritic and austenitic steel types. Almost every structural SS application has duplex or austenitic grade stainless steel varieties. The excellent corrosion resistance of duplex grade stainless steel even in a demanding environment causes it to be an ideal option for marine applications.
Steel fabrication and engineering companies in UAE should do the process of fabricating duplex SS with only purpose-built tools. For them, it is important to thoroughly clean work surfaces and tooling before use. That precaution is essential to avoid stainless steel’s cross-contamination by corrosive metals that can discolor the fabricated item’s structure. As a steel fabricator in UAE, we follow these precautions and best practices in the industry.
This stainless steel variety usually has a carbon consistency of only up to 0.1% and 10.5% to 30% chromium. It is a magnetic stainless steel variety that can resist stress corrosion cracking (SCC) and temperature oxidation. Nevertheless, it is less durable, formidable and tough than austenitic SS. Besides, it is a potentially complex material for steel fabrication and engineering companies in UAE to deal with.
This stainless-steel variety not only has superior corrosion resistance and as much as 1.2% carbon content but it is usually stronger too. That said, lower-carbon martensitic steel varieties are available too. It is possible to harden martensitic steel considerably. As a structural steel fabricator in UAE, we know that it has great potential with regard to fabrication thanks to the above-mentioned factors.
