The temperature of Stainless Steel 904L Bush Hex Pipes should not exceed 900 Degree C (1650 Degree F) at any time and slow cooling below 649 Degree C (1200 Degree F) can cause loss of ductility. 904L Stainless Steel Pipes are also more difficult to cold work rather than other stainless steels, because of its high level of chromium content. Stainless Steel 904L Electropolish Pipes is used to make components and tools that need an extremely high temperature resistance. Buy Stainless Steel 904L Rectangular Pipes at reasonable cost from us. However, the last 10 percent of hot working in SS 904L Square Pipe has to be performed below 871 Degree C (1600 Degree F) to gain grain refinement. The hot working of Stainless Steel 904L Round Pipe is performed in between the ranges 1093 Degree C – 1177 Degree C (2000 Degree F – 2150 Degree F).

 

LIST OF STAINLESS STEEL 904L PIPES

Stainless Steel 904L ERW Pipes can be easily welded using most of the traditional methods except oxyacetylene welding. Differences in coefficient of thermal expansion of base and weld metal in SS 904L EFW Pipes has to be taken into consideration. Machinability of Stainless Steel 904L Welded Pipes is possible at slow speeds with positive feeds, rigid mounts and sharp tooling surfaces. SS 904L Seamless Pipes polishes well, and is good for deep drawing. We are a distributor of SS 904L Pipes, which has good weldability, brightness, and pitting corrosion resistance.
