Abstract

The invention discloses a stainless steel clad flat steel and a figured steel comprising a flat steel, a figured steel layer and a stainless steel layer. The flat steel and the figured steel layer are covered by the stainless steel layer in the length direction; a fusion layer is arranged between the stainless steel layer and the figured steel layer; the thickness of the stainless steel layer is 0.2 to 2.5 millimeters. The provided stainless steel clad flat steel and figured steel is made through combination of a vacuum fusion layer which has high bonding strength and high temperature resistance and gives steel bars with excellent corrosion resistance and mechanical performance. The stainless steel clad flat steel and figured steel can be widely applied in steel structures exposed in environment with high chloride ion content or corrosive industry, such as bridges, harbors, islands, electricity, corrosion, high temperature and machinery.

Description

technical field [0001] The invention relates to a building material, in particular to a stainless steel clad flat steel and a special-shaped steel body. Background technique [0002] Cladding flat steel and special-shaped steel are important raw materials for the production of construction, chemical, electric power, transportation and machinery industries. Cladding flat steel and special-shaped steel are easy to rust under natural conditions, especially in places with high humidity such as coastal areas. Corrosion, which may lead to durability failure of steel materials. In addition, in order to improve the corrosion resistance of construction structures in various industries, stainless steel materials are sometimes used in important structural parts such as bridges, steel structure buildings, overpasses, chemicals, electric power, machinery, etc. Although this all-stainless steel material improves the corrosion resistance Corrosion and oxidation properties prolong the serv...
