What is 0Cr18Ni9Cu3 stainless steel?

0Cr18Ni9Cu3 stainless steel is a kind of austenitic stainless steel, which belongs to the grade of GB/T 1220-1992 standard in my country, and it corresponds to XM7 stainless steel of American ASTM standard.

What are the characteristics of 0Cr18Ni9Cu3 stainless steel?

0Cr18Ni9Cu3 stainless steel is a steel grade that adds Cu to the grade 0Cr19Ni9 to improve cold workability. The corrosion resistance of 0Cr18Ni9Cu3 steel is similar to that of 0Cr18Ni9. It has good rust resistance in wet steam, salt spray and marine atmosphere; in acidic medium, it is resistant to oxidizing nitric acid corrosion, and has poor corrosion resistance in reducing acid, but it is better than 0Cr18Ni9. Can be used as cold heading.

What is the chemical composition of 0Cr18Ni9Cu3?

0Cr18Ni9Cu3 stainless steel is a high-alloy austenitic stainless steel with good corrosion resistance, weldability and formability. The alloy contains 18% chromium, 9% nickel, 3% copper and 0.15% molybdenum. It is nonmagnetic in the annealed condition but becomes slightly magnetic when cold worked. This alloy has excellent resistance to intergranular corrosion and stress corrosion cracking. The specific chemical composition is as follows:

Carbon C: ≤0.08

Silicon Si: ≤1.00

Manganese Mn: ≤2.00

Sulfur S: ≤0.030

Phosphorus P: ≤0.035

Chromium Cr: 17.00～19.00

Nickel Ni: 8.50～10.50

Copper Cu: 3.00～4.00

What are the mechanical properties of 0Cr18Ni9Cu3 stainless steel?

Tensile strength σb (MPa): ≥480

Conditional yield strength σ0.2 (MPa): ≥177

Elongation δ5 (%): ≥40

Reduction of area ψ (%): ≥60

Hardness: ≤187HB; ≤90HRB; ≤200HV

What is the heat treatment specification and metallographic structure of 0Cr18Ni9Cu3 stainless steel?

Heat treatment specifications: solid solution 1010 ~ 1150 ℃ rapid cooling.

Metallographic structure: The structure is characterized by austenitic type.

What is the delivery status of 0Cr18Ni9Cu3 stainless steel?

0Cr18Ni9Cu3 stainless steel is generally delivered in a state of heat treatment, and the type of heat treatment is specified in the contract; if not specified, it is delivered in a state of no heat treatment.

What are the advantages of 0Cr18Ni9Cu3 stainless steel?

0Cr18Ni9Cu3 stainless steel is a premium corrosion resistant material ideal for a wide variety of applications. Its exceptional strength and durability make it an excellent choice for exterior cladding, kitchenware and other products requiring a high level of wear resistance. Additionally, XM7 stainless steel is non-magnetic and low in carbon, making it ideal for medical devices and food processing equipment.

What are the disadvantages of 0Cr18Ni9Cu3 stainless steel?

0Cr18Ni9Cu3 stainless steel is a molybdenum-containing austenitic stainless steel. This makes the steel more resistant to corrosion and pitting. However, XM7 stainless steel also has some disadvantages.

First of all, 0Cr18Ni9Cu3 stainless steel is more expensive than other types of stainless steel. This is because molybdenum increases production costs. Second, 0Cr18Ni9Cu3 stainless steel is not as widely used as other types of stainless steel. This makes it difficult to find products made of this steel. Finally, 0Cr18Ni9Cu3 stainless steel is not as strong as some other types of stainless steel. This means it may not be suitable for some applications that require strength.

What are the applications of 0Cr18Ni9Cu3 stainless steel?

There are many different types of stainless steel, each with its own unique properties and applications. 0Cr18Ni9Cu3 stainless steel is an austenitic stainless steel with a chromium content between 17.00 and 19.00. This makes it resistant to corrosion and oxidation, and moderately resistant to stress corrosion cracking. Some of the most common applications for 0Cr18Ni9Cu3 stainless steel include:

- Car exhaust system

-kitchenware

- Surgical Instruments

- Building Decoration

How to maintain 0Cr18Ni9Cu3 stainless steel?

0Cr18Ni9Cu3 stainless steel is a high chromium, molybdenum and nitrogen containing austenitic stainless steel. It has excellent corrosion resistance in both acidic and alkaline environments. The addition of molybdenum increases its corrosion resistance in chloride environments, while the addition of nitrogen increases its resistance to pitting and crevice corrosion.

To care for your 0Cr18Ni9Cu3 stainless steel cookware, please follow these points:

- Wash cookware with warm soapy water before first use.

- Do not use harsh cleaners or abrasive pads on cookware as this will damage the surface.

- After each use, wash cookware with warm soapy water and dry with a soft cloth. If food is burnt or stuck to the surface, soak cookware in warm soapy water for a few minutes before washing.

- Avoid cooking sprays as they can leave a sticky residue on cookware surfaces.

- Be sure to season your cookware regularly to prevent surface rust or discolouration.
