Carbon steel: Carbon steel, also known as carbon steel, refers to the carbon content of less than 2.11% Wc iron carbon alloy. In addition to carbon steel generally contain a small amount of carbon, manganese, sulfur, phosphorus. Carbon steel can be divided according to the use of carbon structural steel, carbon tool steel and cutting steel three categories, carbon structural steel is divided into two kinds of construction steel and machine structural steel. According to the quality of steel can be divided into ordinary carbon steel carbon steel (phosphorus, sulfur higher), high-quality carbon steel (phosphorus, sulfur lower) and high-quality steel (phosphorus, sulfur lower) High-quality steel.
Stainless Steel: Stainless Steel is short for stainless acid-proof steel. It is resistant to weak corrosive medium such as air, steam, water or stainless steel with stainless steel. Chemical resistant medium (acid, alkali and salt chemical immersion Erosion) called corrosion-resistant steel grade steel. Due to the chemical composition of the difference between the two of their corrosion resistance of different ordinary stainless steel generally resistant to corrosion of the chemical medium, while the acid-resistant steel is generally stainless steel.
Brass: Brass is an alloy of copper and zinc. Brass made of copper and zinc is called ordinary brass. Brass is often used in the manufacture of valves, plumbing, air conditioning inside and outside the machine connecting tubes and radiators. Ordinary brass is a copper-zinc binary alloy, the zinc content of a larger range, so the room temperature tissue is also very different. According to the binary state diagram of Cu-Zn, there are three kinds of brass at room temperature: brass containing less than 35% of zinc, the microstructure at room temperature by a single-phase α solid solution, called α brass; zinc The amount of brass in the range of 36% to 46%, the microstructure at room temperature by the (α + β) two phases, known as (α + β) brass (two phase brass) % ~ 50% brass, microstructure at room temperature only by the β phase, known as β brass.
Conclusion: The three materials are for different occasions.Customers should use their own products according to the conditions, such as temperature, pressure, media, etc.AND then make a reasonable choice of suitable materials
