Custom accept SUS303/304 Stainless Steel flat metal washers fasteners for sealing purpose

The washer is generally a flat metal ring, padded between the fitting and the nut, and is usually used to allocate the load of the thread fastener.Other USES are as spacers, springs (belleville washers, wave washers), wear pads, pre-display devices, locking devices.Rubber washers are also used on faucets (valves) to cut off the flow of liquid or gas.Rubber or silicon washers are also available to reduce fan vibration.Usually the outer diameter of the washer is about twice the inner diameter.

metal gasket material

1. Carbon steel: recommended maximum working temperature does not exceed 538 ℃, especially when the medium with oxidizing.High quality carbon sheet steel is also not suitable for use in the manufacture of inorganic acid, neutral or acidic salt solution equipment, if carbon steel under the stress, for the hot water working conditions of the equipment accident rate is very high.Carbon steel gaskets are commonly used in high concentrations of acids and many alkaline solutions.Brinell hardness is about 120.

2. 18-8-304 stainless steel, nickel chromium (18-20% 8-10%), the recommended maximum working temperature does not exceed 760 ℃.- 196 ~ 538 ℃ in the temperature range, prone to stress corrosion and intercrystalline corrosion.Brinell hardness 160.

3. The carbon content of 304L stainless steel does not exceed 0.03%.Recommended maximum working temperature does not exceed 760 ℃.Corrosion resistance similar to 304 stainless steel.The low carbon content reduced the precipitation of carbon from the crystal lattice, and the grain boundary corrosion resistance was higher than that of 304 stainless steel.Brinell hardness is about 140.

4. 316 stainless steel 18-12 (chromium 18%, nickel 12%), in 304 stainless steel increased by about 2% molybdenum, when the temperature increases its strength and corrosion resistance.When the temperature increases than other ordinary stainless steel has higher creep resistance.Recommended maximum working temperature does not exceed 760 ℃.Brinell hardness is about 160.
