Another alloy derived from the change in additive metal is the carbon steel which is obtained by infusing carbon into stainless steel among other metals like iron, chromium, carbon, niobium and titanium the addition of which, brings innovation in the core characteristics of the alloy. The advanced feature of the carbon steel is, that it gets harder and harder in nature during heat treatment, which makes its use in manufacturing products and parts for various high temperature functioning industries very easy. But the increased hardness makes it less ductile and hinders in welding of the carbon steel products. They are specifically forged in low carbon and high carbon steel forms, which decides the kind of process they will undergo in forging the final products.
The buttweld pipe fittings forged from carbon steel are used in high temperature areas where hot water or high pressure liquids flow through the supply. Even steamers in a boiler room flowing through a piping system use carbon steel buttweld fittings, as they get stronger and stronger with increase in temperature. Addition of chromium and carbon in adequate quantities makes the buttweld fittings resistant to external corrosion and abrasion enhancing its physical and mechanical properties.
