Pipe basic materials
Thread Content
I would like to ask for advice. The basic material of the pipeline is 00cr17ni14mo2. How do you see this? What does it refer to specifically? Thank you, and 0cr17ni12mo2
This is an ultra-low carbon stainless steel material. I won’t go into details about its properties here, but they are available in the forum. As for what the poster said, I don’t understand.
00cr17ni14mo2 is commonly known as SUS316L. Stainless steel generally uses an Arabic numeral to indicate the average carbon content (in thousandths)； When the average carbon content is ≥1.00%, use two Arabic numerals to express it. ； When the upper limit of carbon content is less than 0.10%, “0” is used to represent the carbon content. ； When the upper limit of carbon content is ≤0.03% and >0.01% (ultra-low carbon), the carbon content is expressed as “03” ； When the carbon content is upper limit (very low carbon when ≤0.01%), “01” represents the carbon content. When there is no lower limit for carbon content, Arabic numerals are used to indicate the upper limit of carbon content. The expression method of alloy element content is the same as that of alloy structural steel. For example: The grade of stainless steel with an average carbon content of 0.20% and a chromium content of 13% is expressed as "2Cr13” ； The upper limit of carbon content is 0.08%, the average chromium content is 18%, and the nickel content is 9% chromium-nickel stainless steel. Its grade is expressed as "0Cr18Ni9” ； The upper limit of carbon content is 0.12% and the average chromium content is 17%. The grade of sulfur-added free-cutting chromium stainless steel is expressed as "Y1Cr17"” ； High-carbon chromium stainless steel with an average carbon content of 1.10% and a chromium content of 17% is designated as "11Cr7"” ； The upper limit of carbon content is 0.03%, the average chromium content is 19%, and the nickel content is 10% ultra-low carbon stainless steel. Its grade is expressed as "03Cr19Ni10” ； The upper limit of carbon content is 0.01%, the average chromium content is 19%, and the nickel content is 11%. The grade of extremely low carbon stainless steel is expressed as "01Cr19Ni11". The current domestic standards for stainless and heat-resistant steel are revised with reference to JIS standards, but the method of expressing grades of stainless and heat-resistant steel is different from standards in Japan and other countries. We express it by alloy elements and average C content, while Japan expresses it by letters and Arabic numerals indicating the purpose.
Agree with the third floor's statement and add: 00cr17ni14mo2 is equivalent to SUS316L, 0Cr17Ni12Mo2 is equivalent to SUS316, and the difference between the two is one letter L. in addition, * * A new stainless steel standard has been released, and the above two materials correspond to 022Cr17Ni12Mo2 and 06Cr17Ni12Mo2 respectively.
Very important knowledge, worth learning* !
The third floor explained it very well. What is the brand number of 310S?
Thank you so much, very useful knowledge!
