Zhejiang Xintongda Special Steel Manufacturing Co., Ltd supplies stainless steel seamless tube per ASTM A312, ASTM A 213, ASTM A 269..
We supply common grades of stainless steel such as 304/304L and 316/316L,347, 310/S/H, 321/S in standard tube sizes and wall thicknesses.
We can also supply nickel alloys, such as N06600,N06625.N08800.N08825,C-276,C-22
(Super) Duplex Steel is also our mainly grade, including S32750, S32250, S32760 etc. And also 904L, 254SMO etc.
Stainless Steel 321 Pipes is a standard austenitic 18/8 Chromium Nickel Alloy with the addition of Titanium making it an Excellent Choice in Elevated Temperature Environments. The titanium stabilises the Material removing its susceptibility to the effects of intergranular corrosion. 321 is therefore the stainless steel material of choice for applications in working environments up to 9000 C. However, 321 is a much better option in operating temperature environments in excess of 5000 C and therefore have its own merit. In most instances, the Carbon Content of the plate Enables dual 321/321H Certification.

BEVELING
Beveling Stainless Steel tubes contain one end angled, so that it mates with a complementary tube end. Tubes can be beveled for certain applications in order to make welding of stainless steel tubes easier, which saves weld prep time and money compared to hand cutting.
HEAT TREATING & ANNEALING
Zhejiang Xintongda Special Steel Manufacturing Co., Ltd can heat treat stainless steel seamless tube. Heat treating realizes stress as a result of hardening, depending upon the chemistry of the metal being treated. Heat treating is also used for tempering, quenching, normalizing, and solution annealing.
HONING & TURNING
During the honing/turning process, an abrasive rotating tool removes metal from the interior surface of a cylinder, pipe, or tube. The main purpose of honing is to finish the surface to a particular diameter and/or desired cylindrical geometric design. Honing is typically a secondary machining operation that completes a produce/part, relieves stress created during production, or corrects features of the finished product. A typical production cycle is to drill, ream, heat treat, then hone.
POLISHING POSITIVE MATERIAL IDENTIFICATION (PMI)
In some cases, it may be necessary to complete additional positive material identification testing. XTD can complete this testing in house or we can work with an independent laboratory to complete the testing. Please contact us for specific requirements.
