Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 904L Tubes, which is commonly welded for applications under 1450 Degree F. Stainless Steel 904L Seamless Tubes is a nickel – base alloy used both for its high strength and outstanding aqueous corrosion resistance. The strength of Stainless Steel 904L Welded Tubes is primarily a solid solution effect from molybdenum and columbium. Stainless Steel 904L Round Tubes has excellent weldability and is frequently used to weld, where matching filler metals are also used to join dissimilar metals. Stainless Steel 904L Square Tubes is an austenitic heat resistant alloy designed for high temperature structural applications.

The strength of Stainless Steel 904L Rectangular Tubes is achieved by controlled levels of carbon, Aluminium, and titanium along with a 2100 Degree F minimum annealing to achieve a grain size or coarser. Stainless Steel 904L Welded Tubes offers a closer match of thermal expansion coefficient, and somewhat higher strength. To avoid possible stress relaxation grain boundary cracking of Stainless Steel 904L Instrumentation Tubes in applications above 1000 Degree F the welded fabrication may be heated 1650 Degree F for about one hour per inch of thickness or 30 minutes minimum then air cooled.
Stainless Steel 904L High Pressure Tubes, also known as solid solution strengthened grade, has good strength and excellent oxidation resistance to 2000 Degree F. Stainless Steel 904L Heat Exchanger Tubes are available in different shapes, sizes and designs to our esteemed clients.
