Steel is an alloy consisting mostly iron. Depending on the grade it contains
between 0.2% and 2.1% of carbon that is the most cost-effective alloying
material.
Apart of carbon, there are various other alloying elements used (manganese,
chromium, vanadium, and tungsten). Carbon and other elements act as a
hardening agent. Varying the amount of alloying elements in the steel
controls the hardness, ductility, and tensile strength of the
resulting steel. Steel with higher content of carbon is less ductile but
can be made harder and stronger than iron. These alloys are known as
cast iron for their lower melting point and castability.
Two distinguishing factors for steel with small amount of carbon are steel's
increased rust-resistance and better weldability.
Steel is one of the most common materials and is a major component in
buildings, infrastructure, tools, ships, automobiles, machines, and
appliances.
We have a large unit, engaged in manufacturing and exporting galvanized steel pipes / tubes welded black pipes / tubes, electro-galvanized tube / pipe. We produce low-carbon steel, such as the purpose of the structure and mechanical and general engineering purposes, water, natural gas pipelines and sewage treatment explosive remnants of war property management scope of application of steel pipes, used for belt conveyors, water wells and blood on the pipe steel care Roll governing all aspects of automotive and industrial applications.
