On November 30, the 1800 MPa hot-formed automotive steel developed by HGTG Special Steel Technology Group for new energy automotive customers successfully rolled off the production line, and its performance, plate shape and other indicators met the needs of customers. The successful development of this product indicates that HGTG has the ability to produce full-strength ultra-high-strength hot-formed steel in industrial production.
With the development of automobiles in the direction of lighter weight, safety, energy saving and environmental protection, car companies have more urgent demand for cost-effective ultra-high-strength automobile steel. 1800 MPa hot-formed automotive steel is one of the current high-strength automotive materials. Compared with the commonly used 1500 MPa-grade hot-formed automotive steel, it can achieve a weight reduction of 10% to 15%. It is widely used in automotive A-pillars, The production of components such as B-pillars, bumpers, roof frames, underbody frames, and door anti-collision bars has continued to increase in proportion to the weight of the body and its usage.
The new energy vehicle customer previously used 2000 MPa grade hot-formed automotive steel for the above-mentioned important safety components. After the customer, HGTG and a third-party testing agency conducted a joint material application analysis, it is believed that some of the customer’s safety parts can be made of 1800 MPa class hot-formed automotive steel, which not only meets the vehicle safety requirements, but also improves the delayed crack resistance of the material , To achieve the requirements of safety, light weight, environmental protection and economy.
In response to the individual needs of customers, the HGTG technical team worked closely with the production line personnel. Based on the past experience in high-strength automotive steel production, the advantages of the production line were developed to develop a 1800 MPa-class hot-formed automotive steel production plan, and follow up and guide the production to ensure that the products are All indicators meet customer needs.
