High Tensile Stamped Parts

XIAYI High Tensile Stamped Parts are automotive structural components manufactured with high tensile steel materials and precision stamping technology. Designed for shock absorber support systems, chassis reinforcement structures and heavy-load suspension applications, these components provide improved tensile strength, impact resistance and fatigue durability compared with conventional stamped steel parts.

By selecting graded high-strength steel substrates and combining progressive stamping forming with stress relief treatment, XIAYI develops structural components that maintain stable performance under repeated vibration, heavy loads and complex road conditions. The products are widely applied in SUVs, new energy commercial vehicles, light trucks and engineering machinery requiring higher structural reliability.

High Strength Material Selection

The mechanical performance of automotive stamped components largely depends on steel grade selection. XIAYI uses professional high-tensile steel materials to improve load-bearing capability and structural durability.

Compared with ordinary low-strength steel stamped parts, high tensile materials provide better resistance against deformation, impact loads and repeated stress during vehicle operation.

ST14 Heavy Duty Steel

ST14 high-tensile deep-drawing steel provides excellent ductility with tensile strength up to 320MPa and elongation ≥40%.

The material structure supports complex forming requirements while maintaining strong impact resistance for heavy-load vehicles and harsh operating environments.

ST12 Standard High Strength Steel

ST12 high-strength cold rolled steel offers tensile strength of 280MPa and elongation ≥35%, suitable for conventional passenger vehicles and urban transportation applications.

XIAYI selects suitable material grades according to vehicle load requirements, climate conditions and expected service life.

Structural Fatigue Resistance

Automotive suspension components experience continuous vibration, impact and alternating loads during driving. Material fatigue resistance directly affects long-term structural reliability.

XIAYI High Tensile Stamped Parts are optimized for repeated loading conditions to reduce permanent deformation and fatigue-related failures.

Improved Load Bearing Capacity

The high tensile steel structure maintains stable mechanical strength under heavy compression, lateral impact and frequent vibration.

This helps prevent common failures such as flange deformation, cracking and structural displacement during long-term operation.

Stable Performance Under Vibration

Through optimized material matching and forming control, XIAYI improves resistance against cyclic stress generated during vehicle driving.

The stable structure helps maintain accurate shock absorber positioning and supports consistent suspension performance.

Precision Stamping Process

XIAYI applies multi-station progressive stamping technology to achieve efficient and consistent production of high-strength structural components.

Progressive Forming Control

The progressive stamping process completes shaping, reinforcement forming, hole positioning and trimming through continuous production steps.

The controlled forming method reduces local stress concentration and maintains wall thickness tolerance within ≤0.02mm.

Stress Relief Treatment

After stamping, components undergo 4-hour constant-temperature aging treatment at 120℃ to release residual forming stress.

Secondary 3D calibration ensures dimensional stability under temperature changes ranging from -40℃ to 110℃.

Surface Protection Options

Vehicle structural parts operate in different environments including coastal salt fog areas, humid regions and northern cold climates. XIAYI provides customized corrosion protection solutions according to application requirements.

Heavy Environment Protection

Heavy-duty high tensile components adopt 12~14μm blue-white zinc passivation coating and pass 500-hour neutral salt spray testing.

The coating improves resistance against salt corrosion and protects structural integrity during long-term outdoor operation.

Standard Corrosion Resistance

Standard components use 10μm zinc coating with 420-hour salt spray resistance.

The treatment provides reliable protection for general vehicle applications while maintaining production efficiency.

Quality Inspection Control

XIAYI controls product quality throughout the complete manufacturing process, from incoming steel inspection to final dimensional verification.

Material Inspection

All steel coils undergo spectral impurity detection and non-destructive testing to ensure stable material performance.

The inspection process prevents low-quality materials from affecting forming performance and service durability.

Full Dimensional Verification

Equipped with 6-channel 3D optical scanning equipment, XIAYI performs full-dimensional inspection on finished products.

The production process achieves batch stability CPK≥1.67 and factory defect rate lower than 0.1%.

Industry Application Cases

Mountain SUV Heavy Load Application

Off-road SUVs operating on mountain roads experience frequent impact loads and severe vibration.

A professional off-road vehicle supplier adopted XIAYI ST14 high tensile stamped structural parts to replace conventional stamped components. After two years of full-load road testing, no structural cracking or damping instability occurred, reducing chassis maintenance failure rate by 90%.

Coastal New Energy Vehicle Application

New energy commercial vehicles operating in coastal regions require both structural strength and corrosion resistance.

A coastal new energy vehicle OEM selected XIAYI High Tensile Stamped Parts with 500-hour salt spray protection. After three years of market operation, no structural rust failure or fatigue deformation was reported.

Northern Engineering Machinery Application

Engineering machinery working in northern regions faces low temperature impact and heavy vibration loads.

A northern machinery manufacturer adopted XIAYI high tensile steel structural components. The products maintained stable toughness and structural performance under -40℃ operating conditions.

Application Range

XIAYI High Tensile Stamped Parts are suitable for shock absorber structures, chassis reinforcement components, suspension support parts and heavy-duty automotive applications.

The products are widely used in SUVs, new energy commercial vehicles, light trucks, off-road vehicles and construction machinery.

XIAYI provides OEM and ODM customization services, including steel grade selection, thickness adjustment, structural optimization and surface treatment requirements.
