S32168 stainless steel wire mesh material, grade, characteristics, and application introduction
S32168 is a Chinese material, its grade is 06Cr18Ni11Ti, and its ASTM grade is S32100
German brand: X10CrNiTi189
Austenitic stainless steel is equivalent to domestic grade 0Cr18Ni10Ti
Chemical composition: C: ≤0.08 Si: ≤1.00 Mn: ≤2.00 Ni: 9.00-12.00 Cr: 17.00-19.00 Ti: ≥0.4 Heat treatment: Solution 920-1150℃ rapid cooling
Chemical composition: Carbon: 0.08 Silicon: 1.00 Manganese: 2.00 Phosphorus: 0.045 Sulfur: 0.030 Nickel: 9.00-12.00 Chromium: 17.00-19.00 Titanium: 5C-0.70
S32168 stainless steel wire mesh is Ni-Cr-Mo type austenitic stainless steel, its performance is very similar to 304, but due to the addition of titanium, it has better resistance to intergranular corrosion and high temperature strength. Due to the addition of titanium, the formation of chromium carbide is effectively controlled.
S32168 austenitic stainless steel has good corrosion resistance in the atmosphere and is widely used in industries such as petrochemicals, electricity, bridges, and automobiles [1]. However, the "stainlessness" of stainless steel is not absolute. Due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, and temperature have a great impact on the corrosion resistance of stainless steel. For example, stainless steel will suffer from intergranular corrosion after long-term use in the sensitization temperature range of 450~850℃. The mechanism is that C combines with Cr at the grain boundary to form Cr23C6 and precipitate, which reduces the Cr content at the grain boundary. This is the so-called "chromium depletion". The Cr element is one of the main elements that inhibit intergranular corrosion. When the Cr content at the grain boundary is less than 12%, the probability of intergranular corrosion will increase.
Product features: excellent processability, weldability, impact strength, good atmospheric corrosion resistance and many organic and inorganic chemical corrosion resistance. Its performance is very similar to 304, and due to the addition of titanium, the formation of chromium carbide is effectively controlled, making it have better resistance to intergranular corrosion and high temperature strength.
Features: Excellent resistance to intergranular corrosion, high strength after cold working. Applications: welding rod cores, anti-magnetic instruments, medical equipment, acid-resistant containers, pipelines and other equipment and components.
Industry Applications:
Applicable to outdoor machines in the chemical, coal, and petroleum industries that require high resistance to intergranular corrosion, heat-resistant parts for building materials, and parts that are difficult to heat treat.
