ZhejiangZhongzheng 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
