Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 304H Nipple, which has carbon content and is a preferred choice for high temperature applications. SS 304H Hexagon Reducing Nipple has good resistance to oxidation at temperatures of up to 1040 Degree C (1904 Degree F) in intermittent service and 1150 Degree C (2102 Degree F) in continuous service. Stainless Steel 304H Hexagon Nipple is widely used in environments where Sulphur dioxide gas is present at high temperatures. However SS 304H One End Threaded Nipple is recommended that this steel should not be continuously used at 425 Degree C – 860 Degree C (797 Degree F – 1580 Degree F) range due to carbide precipitation.
Stainless Steel 304H Both End Threaded Nipple does not perform in reducing, nitriding or carburizing atmospheres, but it does outperform most heat resistant stainless steels in these conditions. Stainless Steel 304H Concentric Swaged Nipple is prone to inter – granular corrosion after long term exposure at high temperatures.
However, due to its high chromium content, Stainless Steel 304H Eccentric Swaged Nipple is more corrosion resistant than most heat resistant alloys. 304H Stainless Steel Nipple is quite ductile and forms in a manner very similar to 316, where good characteristics suited to all standard methods and generally recommended for fusion welding. When heated between 1202 Degree F – 1742 Degree F (650 Degree C – 950 Degree C), Grade 304H Nipple is subject to sigma phase precipitation.
