Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality SMO 254 Washers, which is stabilized against chromium carbide formation by the addition of titanium. SMO 254 Flat Washers 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. SMO 254 Lock Washers 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.

SMO 254 Sealing Washers is a heat resistant, titanium stabilized, austenitic alloy that’s commonly used for service in the 1000 Degree F – 1600 Degree F temperature range. A limitation of SMO 254 Split Washers is that titanium does not transfer well across a high temperature arc, so is not recommended as a welding consumable. SMO 254 Slot Washers is a modification of Stainless Steel 321 with a higher carbon content, to provide improved high temperature strength.
SMO 254 Machine Washers is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800 Degree F – 1500 Degree F. SMO 254 Star Washers was developed for use in the chromium carbide precipitation range of 1800 Degree F – 1500 Degree F (427 Degree C – 816 Degree C) where un – stabilized alloys such as 304 are subject to inter – granular attack.
