What is the difference between cast steel and carbon steel?
1. Steel is classified by chemical composition
(1) Carbon steel: a. Low carbon steel (C≤0.25%) b. Medium carbon steel (C≤0.25~0.60%) c. High carbon steel (C≤0.60%)
Steel is classified by forming method: (1) forged steel (2) cast steel (3) hot rolled steel (4) cold drawn steel. The so-called cast steel and carbon steel are just the names generated by different classifications of steel.
What is the difference between forged steel valves and cast steel valves?
Forging and casting are two different processing techniques.
Casting: Molten liquid metal fills the cavity and cools. Air holes are easily generated in the middle of the workpiece.
Forging: It is mainly formed by extrusion at high temperature. Grains in parts can be refined.
Forging: Using methods such as hammering, the metal material in the plastic state is made into a workpiece with a certain shape and size, and its physical properties are changed.
Casting: The metal is heated and melted, poured into a sand mold or mold, and solidified into a vessel after cooling.
During the forging process, the metal is plastically deformed to refine the grains.
What is the difference between cast iron valves and cast steel valves? The main difference between cast iron and cast steel valves is the carbon content, which directly affects the strength and plasticity of the steel. Carbon steel, also known as carbon steel, is an iron-carbon alloy with a carbon content of less than 2% WC. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur, and phosphorus. Carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel according to its use. Carbon structural steel is divided into building structural steel and mechanical manufacturing structural steel. According to the carbon content, carbon steel can be divided into low carbon steel (WC≤0.25%) and medium carbon steel (WC0.25%-0.
The full name of carbon steel is carbon structural steel. Cast steel valves are also carbon steel valves (cast iron valves are also available). They are only made by casting method, while ordinary steel is made by rolling. The ingredients are the same.
What is the difference between cast steel, cast iron and carbon steel in valve materials? In simple terms, you first differentiate between iron and steel. Both steel and iron are alloys with iron and carbon as the main added elements, collectively referred to as iron-carbon alloys.
Cast iron is smelted in an iron furnace to obtain cast iron (liquid state), and the liquid cast iron is cast into castings, called cast iron.
What is the difference between cast steel and carbon steel.
1. Steel is classified by chemical composition
(1) Carbon steel: a. Mild steel (C≤0.25%); b. Medium carbon steel (C≤0.25~0.60%); C. High carbon steel (C≤0.60%).
Steel is classified by forming method: (For valves with different pressures, different materials are used.
Medium and low pressure valve, the valve body material is cast iron. For high pressure valves, due to the high pressure, the valve body must be made of cast steel. Special valves are available in various alloy materials and stainless steel.
It is said that carbon steel is only a kind of steel, and cast steel is a processing method of steel, not a concept.
What is the difference between a carbon steel gate valve and a cast steel gate valve. Many people think that carbon steel gate valves and cast steel gate valves are two materials.
1. Cast steel check valve and carbon steel check valve are check valves made of the same material, both of which are made of WCB A216 carbon steel.
2. Cast steel check valve, because the valve body made of WCB is cast, so as the name suggests, it is called cast steel check valve.
3. Carbon steel check valve, because the main material of WCB material is carbon steel, so it is called carbon steel check valve.
The forging process of steel differs in the form of processing. Cast Steel Steel used for casting castings. A cast alloy. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel. Cast steel refers to a kind of steel casting produced by casting method. Cast steel is mainly used to manufacture some parts with complex shapes that are difficult to forge or cut, but require high strength and plasticity. Forged steel: Forged steel refers to various forgings and forgings produced by forging methods. The quality of steel forgings is higher than that of steel castings, can withstand greater impact force, and has mechanical properties such as plasticity and toughness.
