SAPH370 Steel FAQS
What is SAPH370 steel？
SAPH370 steel is a hot-rolled pickled steel produced by Baosteel, which is mainly used for automotive structural parts, such as car frames and wheels. It is a high-strength steel that is easily formed and welded, making it an ideal material for many automotive applications.
What is the surface treatment of SAPH370 steel?
The main surface treatment method of SAPH370 steel is pickling. SAPH370 steel is a hot-rolled steel. It has a high temperature when it is just rolled, and its surface is covered with iron oxide scale. , At this time, it is necessary to remove the iron oxide scale on the surface by pickling to improve its surface quality. Pickling can clean the surface of the strip steel very well, and can effectively remove the iron oxide scale and some corrosion-resistant substances on the surface of the strip steel. After the pickling unit removes the oxide layer and trims the edges, SAPH370 pickled sheet is an ideal substitute product between hot-rolled sheet and cold-rolled sheet.
What is the production process of SAPH370 steel?
The production process of Baosteel SAPH370 pickling steel plate is as follows:
Burning coal and iron ore – blast furnace – converter – rough rolling – hot rolling mill – laminar cooling system – coiler
What is the chemical composition of SAPH370 steel?
The chemical composition of SAPH370 steel includes carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S) and aluminum (Al). These elements combine to give the steel the desired mechanical properties. For example, adding aluminum helps improve steel’s strength-to-weight ratio, making it ideal for use in automotive components that need to save weight. The specific chemical composition of SAPH370 steel is as follows:
Carbon content C≤0.21%
Silicon content Si≤0.30%
Manganese content Mn≤0.75%
Phosphorus content P≤0.035%
Sulfur content S≤0.035 %
Aluminum content Alt≥0.010%
What are the mechanical properties of SAPH370 steel?
SAPH370 steel has good weldability and impact resistance. The nominal tensile strength of SAPH370 steel exceeds 370MPa, and the minimum elongation of SAPH370 steel is 22%. See the table below for details:
|SAPH370||The yield strength|
|Tensile strength||Nominal thickness|
How is SAPH370 steel made?
SAPH370 steel is made by heating, rolling and cooling process. The process of manufacturing SAPH370 steel begins with the Basic Converter Furnace (BOF) method, which turns scrap metal into a liquid state. After the scrap is melted, it is poured into molds called ingots. These ingots are then rolled into sheets about 3mm thick. Once the sheets are rolled, they are cooled and passed through a series of rollers to achieve the desired thickness. Finally, SAPH370 steel is annealed or heat-treated to soften it before it can be used in automobile manufacturing.
What are the properties of SAPH370 steel?
SAPH370 steel is a high-strength automobile steel with excellent dent resistance and formability The bullet is small and has high strength.
SAPH370 steel also has the advantages of high strength and good formability, and is an important material for automotive structural parts. It can be used in a variety of automotive components, including body panels and axles. Steel produced by the hot rolling process has higher mechanical properties, such as tensile strength and yield strength, which make it ideal for use in automobiles.
What is the difference between SAPH370 steel and SAPH310 steel?
These two steels are hot-rolled pickled steel plates produced by Baosteel, but their grades are different. The numbers 370 and 310 in the grades represent the tensile strengths of the two steels are 370MPa and 310MPa respectively. The tensile strength refers to the During the manufacturing process, the maximum stress value reached from the beginning to the breakage of the material during the stretching process indicates the resistance of the steel to fracture. It is obvious that SAPH370 steel has a higher resistance to deformation.
What are the advantages of SAPH370 steel?
SAPH370 steel is an automotive structural steel used in the production of automobiles and motorcycles. It has many advantages over other types of steel, including:
– Highly abrasion and corrosion resistant, ideal for use in vehicles exposed to harsh conditions.
– It has a high strength-to-weight ratio, making it ideal for use in vehicles where weight is a critical issue (eg racing cars).
-Easy to weld and process, ideal for body panels and other components.
Overall, SAPH370 steel is an excellent choice for many applications due to its high strength and good formability. Its combination of properties makes it an excellent choice for automotive parts requiring high performance and low cost production. It can also be used in other applications such as machine parts, pipes or frames where corrosion resistance is not critical but the strength and ductility of mild steel is still required for good effect. With all these properties in mind, SAPH370 steel might be just the right material for your next project!
