What is 00Cr17Ni14Mo2 stainless steel?

Stainless steel refers to steel resistant to weak corrosive media such as air, steam, water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. In practical applications, the steel resistant to weak corrosion medium is often called stainless steel, and the steel resistant to chemical medium corrosion is called acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Stainless steel is a commonly used material in many industries due to its superior strength, durability and corrosion resistance. 00Cr17Ni14Mo2 stainless steel is an ultra-low carbon stainless steel that complies with the Chinese GB/T 1220 standard, corresponding to 316L stainless steel among the endlessly expensive grades in the United States.

How about the corrosion resistance of 00Cr17Ni14Mo2 stainless steel?

Due to the high chromium and molybdenum content, 00Cr17Ni14Mo2 stainless steel has excellent resistance to pitting and corrosion in many aggressive environments. The low carbon content of 00Cr17Ni14Mo2 also gives this grade of stainless steel good weldability.

Can 00Cr17Ni14Mo2 stainless steel withstand high temperature?

00Cr17Ni14Mo2 stainless steel can be used intermittently below 1600 degrees and continuously used below 700 degrees. The oxidation performance of 00Cr17Ni14Mo2 stainless steel is very superior. In the range of 800-1575 degrees, continuous action is not recommended. When 00Cr17Ni14Mo2 stainless steel is used continuously outside the range of 800-1575 degrees, it has good heat resistance. Since the carbide precipitation resistance of 00Cr17Ni14Mo2 stainless steel is better than that of 316 stainless steel, the above temperature range can be used.

What is the welding of 00Cr17Ni14Mo2 stainless steel? 

The composition of 00Cr17Ni14Mo2 makes it a good welder because it has a lower carbon content than other types of stainless steel and is less prone to sensitization—a phenomenon that can cause welds to crack. In addition, 00Cr17Ni14Mo2 can be hot and cold worked and can be welded by all standard welding methods. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 00Cr17Ni14Mo2 stainless steel is used, post-weld annealing is not required.

What are the advantages and disadvantages of 00Cr17Ni14Mo2?

advantage:

1) The appearance of cold-rolled products has good gloss and is beautiful;

2) Due to the addition of Mo, the corrosion resistance, especially the pitting resistance is excellent;

What is the difference between 00Cr17Ni14Mo2 stainless steel and 316 stainless steel?

At present, 316 and 00Cr17Ni14Mo2 stainless steel have been widely used in the market, and 316 and 00Cr17Ni14Mo2 stainless steel itself has a difference.

different, so they are also different in function, so how should we distinguish their functions, then I need to learn from them

Look at the difference.

1. From the perspective of chemical composition, 00Cr17Ni14Mo2 stainless steel has lower carbon content than 316 stainless steel. It can be said that "00Cr17Ni14Mo2" is ultra-low carbon 316 stainless steel.

2. From the perspective of strength, the tensile strength of 316 stainless steel pipe is higher than that of 00Cr17Ni14Mo2 stainless steel pipe, and the tensile strength of 316 stainless steel pipe is required.

Greater than 520MPa, the tensile strength of 00Cr17Ni14Mo2 stainless steel is only required to be greater than 480MPa. This is because carbon (C) is a strong austenite forming element, which can significantly increase the strength of steel.

3. In terms of production cost, the production cost of 316 stainless steel is slightly lower than that of 00Cr17Ni14Mo2 stainless steel, but the difference is not too great.

4. In terms of actual use, since the production cost difference between ordinary 316 stainless steel and 00Cr17Ni14Mo2 stainless steel is not too large, and the corrosion resistance and weldability of 00Cr17Ni14Mo2 stainless steel are significantly better than ordinary 316 stainless steel, so users generally prefer 00Cr17Ni14Mo2 Stainless steel. The demand for 316 on the market is much smaller than that of 00Cr17Ni14Mo2.
