Product Description

About products

Ordinary carbon structural steel, also known as ordinary carbon steel, has wide restrictions on carbon content, performance range and phosphorus, sulfur and other residual elements. In China and some countries, according to the guarantee conditions of delivery, it is divided into three categories: Class A steel (Class A steel) is steel with guaranteed mechanical properties. Class B steel (Class B steel) is a steel with guaranteed chemical composition. Special steel (Class C steel) is a kind of steel that guarantees both mechanical properties and chemical composition, and is often used to manufacture more important structural parts. At present, A3 steel (Class A No. 3 steel) with carbon content of about 0.20% is the most produced and used in China, mainly for engineering structures. Some carbon structural steels also add a small amount of aluminum or niobium (or other carbide-forming elements) to form nitride or carbide particles to limit grain growth, strengthen the steel and save steel. In China and some countries, in order to meet the special requirements of professional steel, the chemical composition and properties of ordinary carbon structural steel have been adjusted, thus developing a series of professional steel for ordinary carbon structural steel (such as steel for bridges, buildings, reinforcement, pressure vessels, etc.)

hardness
Things made of east and west steel have high enough hardness after heat treatment. For example, things used for metal cutting are generally above HRC60. Under the high cutting speed and high temperature heating conditions produced by machining hard materials, East and West can still adhere to high hardness and excellent red hardness. Carbon east and west steels and alloy east and west steels can still maintain high hardness under the working temperature of 180 ºC~250 ºC and high speed east and west steels at about 600 ºC. Red hardness is very important for hot deformation die and high speed cutting tool steel.
Abrasion resistance
East and west steels have excellent wear resistance, that is, the ability to resist wear. Under the condition of accepting considerable pressure and friction, things can still maintain their shape and standard unchanged.
Strength and resistance
East and west steels have certain strength and resistance, which can accept complex stresses such as load, impact, vibration and bending in work, so as to ensure the normal use of things.
