What is a thermoformed steel plate body part?
(初始强度为500~600MPa)加热至奥氏体化状态，快速转移到模具中高速冲压成形，在保证一定压力的情况下，制件在模具本体中以大于27℃/s的冷却速度进行淬火处理，保压淬火一段时间，以获得具有均匀马氏体组织的超高强钢零件（1300-1600Mpa）。 The boron steel plate (initial strength is 500 ~ 600MPa) is heated to austenitizing state, and it is quickly transferred to the mold for high-speed stamping. Under the condition of ensuring a certain pressure, the product is in the mold body with a The cooling rate is quenched and pressure-quenched for a period of time to obtain ultra-high-strength steel parts (1300-1600Mpa) with a uniform martensitic structure.
Why use hot formed steel body parts?
Extremely high material strength and ductility. 400-450MPa左右，而热成形钢材加热前抗拉强度就已达到500-800 MPa，加热成形后则提高至1300-1600 MPa。 The tensile strength of general high-strength steel plates is about 400-450 MPa, while the tensile strength of hot-formed steels has reached 500-800 MPa before heating, and increased to 1300-1600 MPa after heating forming. Therefore, the body made of hot-formed steel sheet greatly improves the collision resistance and overall safety of the vehicle body, and will play a good role in protecting people in the vehicle during a collision.
Effectively reduce vehicle weight and save energy consumption. Due to the extremely high material strength of the hot-formed steel sheet, one hot-formed part can be used in the design to replace the parts of multiple ordinary steel sheets. A柱加强版、B柱加强版、地板部件、前端等，可为汽车提高安全性，减轻重量。 This kind of part has thin thickness, light weight and high strength, and has less rebound resilience than cold stamping. It is suitable for manufacturing A-pillar reinforced version, B-pillar reinforced version, floor parts, front end, etc., which can improve safety and reduce weight for automobiles.
