Overseas production characteristics of 09cuptire-a steel heat treatment

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in 09CUPTIRE-A steel heat treatment etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

09CUPTIRE-A steel heat treatment, Weathering steel plate is a kind of common steel plate. For ordinary steel plate, if it is used for a long time, it will contaminate the steel surface with a layer of rust, which will seriously affect the normal use of steel. Although the weathering steel plate will produce rust, this layer of corrosion is like a layer of dense oxide film, which is firmly attached to the steel surface to prevent the further corrosion of the base and steel. There are many weathering steel plate manufacturers will adopt some corrosion treatment methods.

09CUPTIRE-A steel heat treatment plate weight: 1) Theoretical weight of 09CUPTIRE-A steel heat treatment plate: The theoretical weight of a steel plate is the weight calculated based on the nominal size and density of the steel plate (previously called specific gravity). It is closely related to the length, size, and cross-sectional area of the steel plate. 2) The actual weight of 09CUPTIRE-A steel heat treatment plate: The actual weight of the steel plate refers to the weight obtained through actual weighing, which is more accurate than the theoretical weight.
