Steel is an excellent alloy when it comes to staying strong in an extremely corrosive environment. The lower the carbon content, the more will be the strength of the alloy against rust and other damages. It is harder than other metals and is economical in many respects. Once employed, it does not need heavy maintenance and can be durable. There are pipes made pout of the substance that are malleable and ductile so as to take in the critical temperature changes. They are passed through different process of heating and consecutive cooling to increase their strength.
