Product description

347 Stainless Steel Pipe

The 347 stainless steel tube is a brand of stainless steel manufactured in accordance with ASTM standards in the United States. 347 stainless steel pipe is equivalent to china’s 0CR18NI11NB stainless steel pipe.

 

347 Stainless steel tube contains 18% Chromium, 11% nickel. 

347 stainless steel tube =0cr18ni11nb containing NB to improve intergranular corrosion resistance, with increased strength, plastic does not decrease. Reduce the thickness of the material. As a structural strength component.

347 Stainless Steel Tube heat Treatment: solution treatment (℃) 980-1150 fast Cold

In the air or chemical corrosive medium can resist corrosion of a high alloy steel, stainless steel is a beautiful surface and corrosion-resistant performance, do not have to go through the surface treatment of plating color, and play stainless steel intrinsic surface properties, used in a variety of steel, usually referred to as stainless steel. Represents the performance of 13 chromium steel, 18-8 nickel and other high alloy steels.


From the metallographic point of view, because stainless steel contains chromium and make the surface of a very thin chrome film, this membrane separates from the steel and the oxygen in the invasion of corrosion resistance.


In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.

 

This material is not a conventional application material and usually does not have inventory. If necessary, please book in advance.
