Stainless steel is a kind of high alloy steel that can resist corrosion in the air or chemical corrosive medium, stainless steel is a kind of high alloy steel that has beautiful surface and good corrosion resistance, and does not have to go through surface treatment such as plating color, and plays the inherent surface properties of stainless steel, used in many aspects of steel, usually called stainless steel.

Magnesium powder has the characteristics of fammable and explosive, high temperature and dazzling white light when bumedso magnesium powder is widely used in science and technology felds such as mlitanry industry and aerospace industry. in thesteelmaking industry and non-ferrous metal casting, magnesium powder is used as a desulfurizing agent and a purifying agent tomake a reducing agent in the production of rare metals. In the chemical industry, magnesium powder can be used more and more inthe spray, coating and anti-corrosion industries, and is also used in single crystal siicon, polycrystaline siicon and metalurgicalpowder die casting.

Stainless steel profiles are used in engineering construction, based on the good corrosion resistance of stainless steel, so it can make the structural components permanently maintain the integrity of the engineering design. Chromium stainless steel also combines mechanical strength and high extensibility, and is easy to process and manufacture parts to meet the needs of architects and structural designers. After the success of the first practical application, stainless steel profiles are available in standard specifications of stainless steel Angle, flat and square steel.

Stainless steel pipe fittings belong to a kind of pipe fittings, it is made of stainless steel material so called stainless steel pipe fittings, it includes: stainless steel elbow, stainless steel tee, stainless steel four, stainless steel reducing pipe, stainless steel pipe cap, etc., according to the connection method can be divided into socket stainless steel pipe fittings, threaded stainless steel pipe fittings, flange stainless steel pipe fittings and welded stainless steel pipe fittings four categories. Stainless steel elbow is used for turning places of pipe fittings; The flange is used to connect the parts of the pipe with the pipe, connected to the end of the pipe, and the stainless steel tee pipe is used for the place where the three pipes are gathered; Stainless steel four-way pipe is used for the place where four pipes are gathered; Stainless steel reducing pipe is used where two pipes of different diameters are connected. Main stainless steel material: 304, 304L, 316|, 316L.

A heavy non-ferrous material consisting of nickel and other alloying elements. In order to further improve the physical and chemical properties of nickel and meet the requirements of science and technology and industrial development, it is necessary to add appropriate alloying elements in nickel. Nickel alloys belonging to heavy non-ferrous metal materials are mainly nickel alloy for electric vacuum, nickel alloy for thermocouple, Monel alloy, nickel beryllium alloy and nickel-based catalyst alloy for synthetic diamond.
