Japanese Yamashina introduces welded bolts without heat treatment

In October 2023, the Yamashina welding bolts are made of metal materials that do not require heat treatment, which can save the cost of thermal management: improve quality. Due to the use of high-strength materials, poor processability, its manufacturing requires advanced technology. The features of this product are as follows: 1) Using high tensile strength materials 2) Use high-strength materials: the tensile strength is about 800Mpa. No heat treatment hardening of bolts 3) can achieve high-strength welding because the material carbon content is not high, so it has good weldability, can achieve safe, high-strength welding. The method of use is to weld it to the steel plate and erect it.
