12X18H10T is a Russian material eaqual to American material AISI321, the difference of their chemical compostion is 12X18H10T requires C% 0.12 max, P% 0.035 max, Cu% 0.3 max, AISI requires C% 0.08 max, P% 0.045, no Cu% spcified. Generally our raw material could meet both, so they are same to us.

12X18H10T and 08X18H10T tubes are the most popular materials Russian customers import from China, the material is with Ti and 1% more nickel content compare to 304, which makes the material more resistant to intergranular corossion, creep, and high temperature stress rupture.
The size in this order is difficult for factories to produce, thin wall seamless tube requires more production process and is with more cost, further more, the tubes requires 320 grit outside polished, so the wall thickness has to be very good, polishing always deduct wall thickness by 0.05-0.1 mm. Attribute to our good processes control, the tubes are with very good final thickness and surface.

The tubes are used as parts for some machines, and the customer orders very three or four month, very time we deliver good products with fast delivery and best price, as well as safe packing as pictures.
