CAST IRON- HARD BUT BRITTLE FORM OF RAW IRON PRODUCED BY MELTING AND COOLING OF PIG IRON.CARBON CNOTENT OF CAST IRON IS 3% WHEREAS PIG IRON CONTAINS ABOUT 4%OF CARBON. :) ???????????????? IT SEEMS YOU HAVE LOT OF DOUBTS IN METALLURGY.REVISE IT PROPERLY KIRTI????

Tamanna Sharma 6 years ago

Pig iron- ( kacha loha) 4% carbon and various impurities,,,,,,,cast iron- pig iron + O2+ coke ( less 3% only) hard and brittle.

Asna Khan 6 years ago

The iron obtained from blast furnace is called pig iron 'nd it contains 4% carbon &other impurities. Cast iron obtained by melting pig iron with scrap iron 'nd it contains 3% carbon. Thats all;

Disarmament ...arms control and confidence building are important means and corporation.

Muskan Rattan 6 years ago

Disarmament is the process of reducing or eliminating military forces and weapons through cooperation, treaties, and oversight. OR Disarmament is not something that can be easily defined in a few words. In truth, there are four key parts to it: Reduction in quantity of military items Formal meeting and treaty to achieve Emphasis on weapons and tools Body or group overseeing the process These four parts lead to a detailed definition, and a detailed plan of action as well. Disarmament is usually focused on weapons, but can include other areas, such as tools and technologies.
