Green & Pollution free environment, especially hazardous
chemicals is the concern of government, society and corporate.
For example, in Europe they have made a mandatory legislation
– RoHS compliance for Automobiles and WEEE compliance
for Electronic Goods. They have set limits of following hazardous
chemicals in Automobile & Electronic products.
1. Lead (Pb) : Less then 1,000 ppm
2. Mercury (Hg) : Less then 1,000 ppm
3. Cadmium (Cd) : Less then 100 ppm
4. Hexavalent chromium : Less then 1,000 ppm
So European Union have set limits of above hazardous chemicals
in their country and similar legislation expected to be soon
in other developed countries as well. Idea behind is to make
environment pollution free and better life of the future generation.
For corrosion prevention, plating
of hazardous chemicals like lead, cyanide, nickel etc. is
used. Effluent treatment (neutralization) is very tedious
& costly affair so it is drained as such, which is adversely
affecting the environment.
The plating is not required on Stainless Steel Fasteners,
therefore, Stainless Steel is Eco-friendly
material and meeting the stringent
European compliance of RoHS/WEEE. Moreover, disintegration
(corrosion) of Stainless Steel is negligible, so loss of the
value of product is almost nil in long term.
Finally, Stainless Steel is fully re-cyclable,
does not have any hazardous effect - so it is Eco-friendly. |
