The product categories includes heavy plates with high alloy content and homogeneous distribution in thickness and carbon steel plates cladded with all kinds of stainless steels,nickel alloys,and titanium alloys. The double-sided and single-sided cladding hot rolled strips and cold rolled sheets w ere also commercially produced. Due to the combined properties of both the cladding material and backing material,all products show obvious improvement in properties when compared with solid material. The comparability with the existing production process and equipment laid a very solid foundation for high productivity.展开更多
