Audited Supplier
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.
A derivative of stainless steel grade 316, this alloy forms an integral part of applications that involve structure.
A specification like ASTM A312 covers austenitic alloy Stainless Steel 316ti Pipe in both seamless and welded constructions.
The use of these pipes include applications involving elevated temperatures and general corrosion resistance.
The corrosion resistance properties of grade 316 and Stainless Steel 316ti Seamless Pipe are similar. Although due to the addition of titanium in its alloy 316TI offers better weldability and exhibits excellent performance in elevated temperatures

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.
