Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 304H Pipes, which is described as a super stainless steel with a microstructure of 50 / 50 austenite and ferrite. Stainless Steel 304H Seamless Pipes has ambient and sub – zero (down to minus 50 Degree C) notch ductility is good. These attributes mean that Stainless Steel 304H Welded Pipes can be used successfully as an alternative to 300 series stainless steel (such as type 316), standard and precipitation hardening stainless steels. Appropriate Stainless Steel 304H EFW Pipes can be considered in lieu of costlier stainless steel or nickel based alloys.

Stainless Steel 304H Pipes

Providing higher strength in Stainless Steel 304H ERW Pipes than both austenitic and 22 % Cr Stainless Steels is suited to a variety of applications in industries such as Chemical Processing, Oil & Gas, and Marine environments. Stainless Steel 304H Round Pipes exhibits a low coefficient of thermal expansion and higher heat conductivity than austenitic steels and is suitable for working temperatures up to 300 Degree C.

The high – temperature strength of Stainless Steel 304H Square Pipes is basically in the range of 950 Degree C – 1150 Degree C. Stainless Steel 304H Rectangular Pipes should be noted that the strength increases abruptly below 900 Degree C. Regarding cold workability for Stainless Steel 304H Hexagonal Pipes, care is required as proof stress is high and elongation is low in comparison with Type 304.
