What is 00Cr18Ni1ON stainless steel? 

00Cr18Ni1ON is the addition of N to SUS304 steel to make it have the same performance as above. The use of 00Cr18Ni1ON stainless steel is the same as that of SUS304N1 steel, but its resistance to intergranular corrosion is better. SUS304LN corresponds to Japanese SUS304LN and German X2CrNiN18-10.

Features and scope of application: used to manufacture structural parts that require both corrosion resistance and certain strength, such as food equipment, chemical equipment, and atomic energy industries. 

What type of stainless steel is 00Cr18Ni1ON?

The metallographic structure of 00Cr18Ni1ON is austenitic. It belongs to austenitic stainless steel.

What are the characteristics of 00Cr18Ni1ON?

00Cr18Ni1ON is an austenitic stainless steel with high nickel and chromium content. The low carbon content of the alloy makes it suitable for welding and other processes requiring low carbon stainless steels. The alloy has good corrosion resistance in both oxidizing and reducing environments and is resistant to intergranular corrosion.

00Cr18Ni1ON is a low carbon austenitic stainless steel. It has a nitrogen content of 0.1%, which gives it enhanced mechanical properties, making it an ideal material for use in cryogenic environments. The low carbon content also makes it easier to weld and machine than other austenitic stainless steels.

What is the chemical composition of 00Cr18Ni1ON?

What is the thermal performance of 00Cr18Ni1ON?

00Cr18Ni1ON is an austenitic chromium-nickel steel with nitrogen added to produce higher mechanical strength. This results in higher yield and tensile strengths than 304L stainless steel. Therefore, 00Cr18Ni1ON is usually used for heavy parts requiring high strength. In addition, due to the low carbon content, 00Cr18Ni1ON has good weldability and can be welded by all standard fusion welding methods.

What are the advantages of 00Cr18Ni1ON stainless steel?

1. It has excellent stainless corrosion resistance and better resistance to inter-product corrosion. It has strong corrosion resistance to oxidizing acids, such as nitric acid below the boiling temperature with a concentration of ≤65%. It also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.

2. It has excellent cold and hot processing and forming properties. It can process and produce various products such as plates, tubes, wires, strips, and molds, and is suitable for dry manufacturing of cold heading, deep drawing, and deep drawing forming parts.

3. Good low temperature performance. Under the condition of -180℃, the strength, elongation and reduction of area are all very good. Because there is no brittle transition temperature, it is often used at low temperatures.

4. Has good welding performance. It can be welded by the usual welding method, and no heat treatment is required before and after welding.

No one is perfect, and 00Cr18Ni1ON stainless steel also has performance deficiencies. After welding, large cross-sectional steel parts are sensitive to crystal corrosion, low in mechanical strength, and slightly poor in cutting performance.

In general, 00Cr18Ni1ON is a high corrosion resistance austenitic stainless steel. It has excellent weldability, low carbon content and strength superior to other types of stainless steel. Its key properties include high tensile strength, toughness and formability. In addition, it has good low temperature properties and can be used in the oil and gas industry. With proper care and maintenance, this type of stainless steel can last for a long time without any issues.

What are the applications of 00Cr18Ni1ON stainless steel?

00Cr18Ni1ON stainless steel is a kind of chromium-nickel stainless steel widely used. As a kind of widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending, and has no heat treatment. Hardening phenomenon (use temperature -196 ° C ~ 800 ° C).
