We are best Manufacturers, Exporters & Stockists of Alloy 20 Washers in Sri Lanka. Nascent Pipe & Tubes is one of the pioneer trader & exporter in Alloy 20 Washers, which is the higher carbon version of the alloy. Alloy 20 Flat Washers has slightly improved corrosion resistance over stainless steel in strongly oxidizing environments. Alloy 20 Lock Washers is also advantageous for high temperature service because of its good mechanical properties.
Alloy 20 Sealing Washers offers higher creep and stress rupture properties than Alloy 304 and, particularly might also be considered for exposures where sensitization and intergranular corrosion are concerns. Alloy 20 Split Washers is a columbium (niobium) / tantalum stabilized austenitic chromium – nickel stainless steel which was developed to provide an 18 / 8 type alloy with improved inter – granular – corrosion resistance.

Alloy 20 Slot Washers has a slightly improved corrosion resistance over other alloys of stainless steel in strongly oxidizing environments as a result of the addition of columbium (niobium) and tantalum. Alloy 20 Machine Washers was developed for enhanced creep resistance and for higher strength at temperatures above 1000 Degree F (537 Degree C).
In most instances, the carbon content of Alloy 20 Star Washers enables dual certification. Alloy 20 Wire Spring Washers does not perform well in chloride solutions, even in small concentrations, or in sulphuric acid. The slightly higher price point of Alloy 20 Flat Spring Washers is well worth it in areas with high chloride exposure, especially the coast and heavily salted roadways.
