Hot Formed Steel
Hot formed steel, also known as hot-stamped steel or hot press-formed steel, refers to a special type of steel that is formed at high temperatures, typically around 800-950°C. This process allows the material to be shaped into complex geometries while achieving exceptional strength and durability. After forming, the steel is rapidly cooled (quenched), locking in its strength and structural integrity.
Hot-formed steel is often used in industries that require high-strength components with complex designs, such as automotive manufacturing, construction, and aerospace.
Hot-formed steel is a transformative material in modern engineering, offering great performance in terms of strength, design flexibility, and safety. If you would like to purchase or find out more, please feel free to contact us!

Hot Formed Steel
Grade and Application
Hot formed steel refers to the steel used for hot stamping. The steel was heated to above the austenite tem-perature, and was quickly moved onto the die, high temperature slab in the die can be formed and quenched during stamping ,the strength of the parts can reach to 1500MPa and above after taking into shape. this product has been widely used in manufacturing hot stamping parts such as A pillar reinforcing plate, B pillar reinforcing plate and C pillar reinforcing plate, doorsill, carling and chassis drawing structural parts.
| Steel grades | Category | Application |
| LG1500 | cold rolled surface | A pillar, B pillar, front and rear bumper, door bumper bar, etc safety structural parts |
Characteristics of Hot Formed Steel
High Strength
- Achieves tensile strengths up to 1500 MPa or more, making it ideal for structural applications.
Excellent Formability
- Allows for the creation of complex shapes and designs that are difficult to achieve with cold forming.
Dimensional Stability
- Minimal spring back after forming ensures accurate and consistent parts.
Improved Safety Features
- Exceptional crash resistance makes it a critical material for automotive safety components.
Corrosion Resistance
- It can be coated or treated for enhanced resistance to environmental degradation.
Hot Formed Steel Manufacturing Process
Heating
- Steel blanks are heated to 800–950°C, the austenitization temperature, making the material malleable.
Forming
- The hot blank is stamped or pressed into its desired shape in a die.
Quenching
- Rapid cooling within the die locks the material into its final form, transforming its microstructure into martensite for high strength.
Finishing
- Additional processes like trimming, coating, or assembly are applied depending on the application.
Benefits of Hot Formed Steel
Lightweight Design
- Enables the use of thinner sections without compromising strength, leading to weight reduction in applications like vehicles.
Cost Efficiency
- Simplifies manufacturing by combining forming and hardening in a single process.
Enhanced Performance
- Superior crashworthiness and load-bearing capacity compared to cold-formed alternatives.
Versatility
- Can be used in a wide range of industries and is compatible with various coatings for additional functionality.
