Water treatment Steel Body
The steel body of the sewage treatment package consists of a wall and a wall using a 6 mm thick st37 steel plate for the wall and an 8 mm thick st37 steel plate for the floor. An important part of the sewage treatment package is its steel wall and floor part. This wall and floor must be capable of withstanding the pressure applied by the water force. In areas where iron is cut, welding must be carefully painted and stained to always be sealed.
The term ferrous alloys is used to refer to a wide range of alloys whose main constituent is iron or, in other words, iron-based. These alloys are divided into three main groups:
- Working iron
- Cast iron
Cast iron is an alloy of iron and carbon that generally has 3 to 5 percent carbon and 1 to 3 percent silicon.
Steel has been described in the past as an alloy of iron and carbon. Today, despite some of the most important types of steel, such as Interstitial-Free (IF) steels and ferrite stainless steels type 409, in which carbon is an impurity whose content is several parts per million, it is no longer possible to describe iron alloy and Carbon used for steel.
By definition, steel must contain at least 50% iron and one or more alloying elements. These elements usually include carbon, manganese, silicon, nickel, worm, vanadium, molybdenum, titanium, niobium and aluminum.
The most common type of steel is plain carbon steel, which represents steel containing iron and carbon along with varying amounts of manganese, silicon or aluminum. Another important type of steels is alloy steel, which in addition to the above mentioned elements, distinguishes significant amounts of elements such as cream, nickel and molybdenum from simple carbon steel. Particular part of alloy steels are stainless steels having at least 11.5% chromium.
