美国俄亥俄州金属模块公司开发了一种富有生命力的多孔铁素体不锈钢海绵体材料。该料可取代气流多通道陶瓷单块和金属箔单块而用作汽车催化转换器载体结构。这种钢制海绵体不限制排气流动方向。海绵体采用费克拉洛伊合金,即一种含标定的20％铬、5％铝和少量的钇的铁素体不锈钢制造。 根据试验结果,据称采用海绵体为载体的催化转器,其体积仅为0.36L。可达到体 Metal module company Ohio, the United States has developed a vibrant porous ferritic stainless steel sponge material. The material can replace gas multi-channel ceramic monoliths and metal foil monolith and used as catalytic converter car carrier structure. This steel sponge does not limit the flow direction of the exhaust gas. The sponge is made from the Fekralloy, a ferritic stainless steel with a nominal 20% chromium, 5% aluminum and a small amount of yttrium. According to the test results, it is said that a sponge carrier catalyst catalytic converter, the volume is only 0.36L. Reach the body
