Chemical Composition of Austenitic Stainless Steel S30908 0Cr23Ni13

Trust Steel Alloy 0Cr23Ni13

Trust steel alloy is one of the most widely used materials in the modern industrial sphere and is made up of a combination of various metals, including 0Cr23Ni13. Known as a stainless alloy, 0Cr23Ni13 is composed primarily of iron, chromium and nickel. In concentration, it is made up of 0.07 percent carbon, 22.0 to 24.0 percent chromium and 12.2 to 13.9 percent nickel. A trace amount of manganese and silicon may also be present in the alloy. As with any alloy, 0Cr23Ni13 can be given a variety of uses depending upon the specific application it is intended for.

Due to its high chromium content, 0Cr23Ni13 offers a great level of resistance to corrosion, oxidation and a number of other environmental and stress factors. As a result, the alloy has gained popularity in many areas where corrosion can impact the quality of a product over time. One such example of this use can be seen in the manufacture of equipment for chemical production and other areas where perpetual exposure to corrosive substances is of great concern.

The excellent formability of 0Cr23Ni13 makes it a great choice in many areas of production. This means that the alloy can be easily fashioned into a variety of shapes depending on its intended purpose. This formability is further enhanced by its excellent weldability, making 0Cr23Ni13 well suited to application where a bond must be formed between two surfaces.

The ability of 0Cr23Ni13 to resist corrosion and oxidation also renders it useful in a product as it can help prevent an unexpected and dangerous deterioration of a product over time. This gives it applications in medical equipment, as well as many other components that are exposed to corrosive elements. Its mechanical strength also gives it a great level of durability, making it the ideal choice for products which may be subjected to physical stress over time.

Trust steel alloy 0Cr23Ni13 has a variety of applications in today’s industrial sphere, making it a valuable and versatile choice for many production lines. With its combination of excellent formability, weldability, corrosion resistance and mechanical strength, it is an ideal choice for a vast array of projects that require highly-durable and reliable components.

Alloy 309/309S (UNS S30900/S30908) is an austenitic stainless steel, typically used for elevated temperature applications. It contains 23.0-25.0% chromium, 12.0-15.0% nickel, 2.0-2.5% manganese, 1.5-2.0% silicon and 0.1-0.2% carbon. While it is resistant to general corrosion, it exhibits poor performance against crevice and pitting corrosion in both chloride and sulfuric acid environments. This austenitic stainless steel has excellent corrosion resistance along with good formability and toughness.

Chemical Composition of Alloy 309/309S [%]

Cr: 23.00- 25.00

Ni: 12.00-15.00

Mn: 2.00-2.50

Si: 1.50-2.00

C: 0.10-0.20

P: ≤0.045

S: ≤0.03

Alloy 309/309S exhibits greater impact and vibration fatigue resistance than Alloy 304/304L, making it suitable for use in a wider range of applications. Despite its good properties, Alloy 309/309S is more susceptible to surface scale formation and discoloration than Alloy 304/304L and thus, should not be used in applications where exposure to corrosive elements is to be minimized.

Moreover, it is important to note that Alloy 309/309S has much better welding properties compared to other austenitic stainless steels, due to their lower nickel content. Still, post-weld heat treatment should be considered depending on the application.

Overall, Alloy 309/309S offers a great combination of properties and is ideal for applications that require resistance to corrosive elements and are exposed to high temperatures.
