旭化成 Company Profile

Asahi Kasei provides high-quality explosion-welded clad products to customers around the world.

BA Clad is a clad steel plate manufactured by Asahi Kasei using the explosive welding method, and it has received high praise in various fields since its launch. The explosive welding method utilizes the enormous energy released during an explosion to instantaneously bond metal plates together, thereby producing clad steel plates. BA Clad is used for plants and equipment in the chemical industry, petroleum refining, petrochemicals, and power generation, and is exported widely both domestically and internationally, either as flat plates or various components. It is used as corrosion-resistant and heat-resistant structural materials for power plant condenser tube sheets, heat exchanger tube sheets for chemical plants, shells, and end plates, among others, and its applications are continually expanding to include rolling mill liners, electrodes, ultra-low temperature joints, ultra-high vacuum joints, and structural joints for ships and LNG tankers. We propose solutions related to metal joining (dissimilar metal joining, similar metal joining) and cladding. We can provide joining characteristics such as material properties, joining strength, minimization of alloying at the joining interface, and joining area that are difficult to achieve with other joining methods, such as various welding techniques, diffusion bonding (roll bonding, HIP, etc.), friction joining (friction welding, friction stir welding (FSW)), electromagnetic pressure welding, brazing, plating, and thermal spraying.
