Nascent Pipe & Tubes is one of the renowned manufacturer & exporter of high quality Alloy 304 Fasteners (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.
