Sachiya Steel International is one of the renowned manufacturer & exporter of high quality Stainless Steel 304 Washers, which is the family of steels that have a mixed micro – structure of 50 % ferrite and 50 % austenite. Ferritic – austenitic stainless steel also referred to as Stainless Steel 304 Flat Washers, combine many of the beneficial properties of ferritic and austenitic steels.
Stainless Steel 304 Lock Washer offers excellent resistant to corrosion and very high mechanical strength. The high corrosion resistance of Stainless Steel 304 Sealing Washer ensures significantly more uptime than carbon steels and conventional stainless steels, while the mechanical strength allows for lighter constructions, more compact system design and less welding.
The standard austenitic steels like Stainless Steel 304 Split Washers are relatively easy to make and to fabricate. SS 304 Slot Washers has high amount of chromium and a slight amount of nickel. Stainless Steel 304 Machine Washer combines both austenitic (chromium – nickel) and ferritic (chromium only) molecular structures.
As their names imply, Stainless Steel 304 Star Washer consist mainly of one phase, austenite or ferrite. Although these SS 304 Wire Spring Washers are fine for a wide range of applications, there are some important technical weaknesses in both types. Stainless Steel 304 Flat Spring Washer are known to offer exceptional strength and astounding aesthetic qualities along with better resistance against corrosion and high temperature, superior hygienic surface finishing, and improved steel recyclability.
