Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 304L Nipple, which are used because they are not sensitive to inter – granular corrosion after heating within the carbide precipitation range of 425 Degree C – 850 Degree C. A limitation with SS 304L Hexagon Reducing Nipple is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. In general, Stainless Steel 304L Hexagon Nipple is referred as alloy steel when content of Manganese – 1.65 %, Silicon – 0.6 % & copper 0.6 % exceeds the limit.
Stainless Steel 304L One End Threaded Nipple is the grade of choice for applications in the temperature range of up to about 900 Degree C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. Elements with a lower percentage i.e. less than 5 % are added to increase the strength and harden ability of SS 304L Both End Threaded Nipple, whereas in larger percentage to achieve special properties like corrosion resistance, high temperature sustainability, and high yield and impact results.
Stainless Steel 304L Concentric Swaged Nipple is heat resistant, titanium stabilized, austenitic alloy that’s commonly used for service in the 1000 Degree F – 1600 Degree F temperature range. SS 304L Eccentric Swaged Nipple is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800 Degree F – 1500 Degree F.
