Understanding Stainless Steel 18-10 (SUS316) and its Composition
Stainless steel 18-10, also known as SUS316, is a widely used stainless steel grade known for its exceptional properties and composition. Understanding the composition of SUS316 and its unique characteristics is crucial in determining its suitability for various applications.
SUS316 belongs to the family of austenitic stainless steels, which are highly corrosion-resistant and have excellent mechanical properties. The “18-10” designation refers to the composition of this stainless steel alloy, indicating that it contains approximately 18% chromium and 10% nickel.
The presence of chromium in SUS316 provides exceptional corrosion resistance, making it ideal for applications where exposure to corrosive environments is a concern. Additionally, the addition of nickel enhances its resistance to both chemical and atmospheric corrosion.
In terms of composition, SUS316 also contains small amounts of other elements such as molybdenum (2-3%), which further enhances its corrosion resistance against pitting and crevice corrosion. This makes it particularly suitable for use in marine environments or industries involving exposure to chloride-containing solutions.
Furthermore, SUS316 exhibits excellent high-temperature strength and good formability due to its austenitic structure. Its versatility allows it to be utilized in various industries including architecture, food processing, chemical processing, pharmaceuticals, and more.
Understanding the properties and composition of stainless steel 18-10 (SUS316) enables engineers and designers to select the most appropriate material for their specific requirements. With its remarkable corrosion resistance, mechanical strength, and formability characteristics, SUS316 proves itself as a reliable choice among different stainless steel grades and alloys available in the market today.
Chemical Composition of SUS316:
C≤0.08,
Mn≤1.5,
Si≤1.5,
P≤0.04,
S≤0.04,
Cr 18.00-21.00
Ni 9.00-12.00,
Mo 2.00-3.00
Basic Features of SUS316:
(1) Cold-rolled products have good appearance and gloss;
(2) Due to the addition of Mo (2~3%), corrosion resistance, especially pitting corrosion resistance, is excellent
(3) Excellent high temperature strength
(4) Excellent work hardening (weak magnetism after processing)
(5) Non-magnetic in solid solution state
(6) Good welding performance. Welding can be carried out using all standard welding methods. When welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used for welding according to the purpose. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post-weld annealing is not required.
