Abstract

The invention discloses a manufacturing method of a stainless steel door window material. The manufacturing method mainly comprises the following steps of 1, raw material smelting, 2, remelting refining, 3, hot-forging treatment, 4, slag removal, 5, annealing treatment and 6, acid pickling. According to the manufacturing method, the mechanical processing performance of an alloy can be improved through oxygen-blowing decarburization and high-temperature denitrification, a stainless steel raw material is placed in a vacuum sensing furnace to be calcined, the heat transfer efficiency is high, safety and reliability are achieved, impurities in air are prevented from entering the stainless steel door window material, and accordingly the purities of the stainless steel door window material are not affected; the manufactured stainless steel material can be applied to various antitheft windows, door planks, window frames and the like, the good corrosion-resisting effect is achieved, and the elongation and percentage of area reduction are both increased.

Description

technical field [0001] The invention belongs to the field of door and window materials, and in particular relates to a preparation method of stainless steel door and window materials. Background technique [0002] Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel grades that are resistant to weak corrosive media such as air, steam, and water, or have stainless properties are called stainless steel; The steel grade is called acid-resistant steel. [0003] Stainless steel doors and windows are widely used in industrial production because they are not easy to rust, easy to process, relatively low in price, light in weight, and can be made into complex sections and structures. In addition, stainless steel doors and windows are easy to install and clean. [0004] The current stainless steel doors and windows still have the defects of poor toughness and easy corrosion. Contents of the invention [0005] In view of the above problems, the tech...
