High-strength steel plates used for testing molds are important materials in automobile manufacturing, and their performance directly affects the safety, lightweighting, and manufacturing cost of automobiles. By continuously optimizing material properties and mold design, the quality and production efficiency of automotive components can be further improved.

GNEE STEELprovide steel for pre testing and production of new automotive projects, with a minimum order quantity of several hundred kilograms to one or two tons per specification.

Automotive high-strength steel plate for experimental molds is a material specifically used for manufacturing automotive components, with high strength, high toughness, and good formability. This type of steel plate is usually used to manufacture body structural components, chassis parts, etc., to meet the needs of automotive lightweighting and safety. The following are some key points about high-strength steel plates for automotive testing molds:

• Material characteristics

High strength: The strength of this type of steel plate is usually above 500MPa, and can even reach over 1500MPa, which can withstand large loads.
High toughness: While ensuring strength, it has good toughness and can absorb energy during collisions, improving safety.
Good formability: Although it has high strength, it still has good stamping forming performance, suitable for manufacturing complex automotive parts.
Lightweight: High strength steel plates can reduce material thickness while ensuring performance, thereby achieving vehicle lightweighting, reducing fuel consumption and emissions.

Dual phase steel (DP steel): composed of martensite and ferrite, it has high strength and good formability.
Phase transformation induced plasticity steel (TRIP steel): undergoes phase transformation during deformation, further improving strength and toughness.
Martensitic steel (MS steel): Obtained martensitic structure through rapid cooling, with extremely high strength, but relatively poor formability.
Hot formed steel (PHS steel): manufactured through hot forming process, with a strength of over 1500MPa, widely used in vehicle safety structural components.
 

• Requirements for experimental molds

High hardness: Mold materials need to have high hardness to resist stamping deformation of high-strength steel plates.
Wear resistance: Due to the significant frictional force generated during the forming process of high-strength steel plates, the mold needs to have good wear resistance.
High precision: The machining accuracy of the mold requires high precision to ensure the dimensional accuracy and surface quality of the formed parts.
Fatigue resistance: The mold needs to have good fatigue resistance to cope with repeated loads in mass production.

Body structural components, such as A-pillars, B-pillars, door crash beams, etc., require high strength and good collision performance.
Chassis components, such as suspension systems and frames, need to withstand significant dynamic loads.
Safety components, such as bumpers, crash beams, etc., are required to absorb energy during collisions and protect passenger safety.

• Formability test: Evaluate the formability of steel plates through tensile tests, cupping tests, and other methods.
• Strength testing: Evaluate the strength of steel plates through tensile testing, hardness testing, and other methods.
• Collision simulation: Evaluate the performance of steel plates in collisions through computer simulations or actual collision tests.
• Fatigue test: Evaluate the durability of molds and steel plates under repeated loads.
