Sachiya Steel International Is One Of The Leading Manufacturer And Exporter Of High Quality Stainless Steel 347H Pipes, which is easily welded, but the welding procedure is different than that used with carbon steel. These Stainless Steel 347H Seamless Pipes has excellent properties at both extremes of the temperature scale, which can be used down to liquid nitrogen temperatures and some up to about 1800 Degree F. Stainless Steel 347H Welded Pipes can be recycled 100 %, which can be re-melted to make new stainless steel. The typical amount of recycled Stainless Steel 347H EFW Pipes that is used to make new stainless steel is between 65 % & 80 %.When Stainless Steel 347H ERW Pipes contains more than approximately 10 % Chromium it can be classified as a stainless steel.

This is because Chromium in Stainless Steel 347H Round Pipes has a high affinity for Oxygen and forms a stable Oxide film on the surface of the steel, where this film is resistant to further chemical or physical change. Incorrect specification, fabrication or subsequent handling may cause Stainless Steel 347H Square Pipes to stain or discolor, impairing the overall look.
This brown discoloration in Stainless Steel 347H Rectangular Pipes is referred to as “tea staining” and has been identified predominantly on external applications in the overseas. These Stainless Steel 347H Electropolish Pipes can be controlled and does not affect the structural integrity or the longevity of the material.
