Stainless Steel Capillary Tube Sizes Difference

Stainless steel capillary models are of diameter and wall thickness and are quoted from the Japanese system. The following format can be used for comparison. Japanese Standard = Old Standard = New Standard

SUS304 = 0Cr19Ni9 = 06Cr19Ni10

SUS304L = 00Cr19Ni10 = 0Cr19Ni10

SUS316 = 0Cr17Ni12Mo2 = 06Cr19Ni10Mo2

SUS316L = 0Cr17Ni12Mo2N = 06Cr19Ni10Mo2N

These materials represent the content of various elements in the national standard code. The acid and alkali resistance of these materials is 304-304L-316-316L in turn.

Differences among stainless steel capillary tube sizes

The corrosion resistance and pitting corrosion resistance of 200Cr18Ni12Mo2Cu2 are better than that of 0Cr17Ni12Mo2. Sulfuric acid resistant materials

The ultra-low carbon steel 2100Cr18Ni14Mo2Cu2 is 0Cr18Ni12Mo2Cu2, which has better intergranular corrosion resistance than 0Cr18Ni12Mo2Cu2.

Point corrosion resistance of 220C19Ni13Mo3 is better than that of 0Cr17Ni12Mo2. For dyeing equipment materials, etc.

2300Cr19Ni13Mo3 is 0Cr19Ni13Mo3 ultra-low carbon steel, which has better intergranular corrosion resistance than 0Cr19Ni13Mo3.

240Cr18Ni16Mo5 heat exchanger, acetic acid equipment, phosphoric acid equipment, bleaching equipment, etc. for absorbing chloride in solution, used in environments where 00Cr17Ni14Mo2 and 00Cr17Ni13Mo3 are not applicable

251Cr18Ni9Ti as welding bracts, antimagnetic instruments, medical instruments, acid-resistant containers and equipment lining conveying pipes and other equipment and parts
