Stainless steel is generally the general term of stainless steel and acid-resistant steel. The stainless steel is steel weak medium corrosion resistance to atmospheric, steam and water, and acid-resistant steel is resistant to acid, alkali, salt and other chemical etching medium corrosion of steel. Stainless steel come out since the beginning of this century, and now has 90 years of history. The stainless steel of the invention is a significant achievement in the history of the world metallurgical laid an important material and technological base of the stainless steel of the development of modern industrial development and technological progress. Stainless steel grades, with different properties in the development process, it gradually formed a few categories. Organizational structure divided into martensitic stainless steel (including precipitation hardening stainless steel), ferritic stainless steels, austenitic stainless steel and austenitic ferritic duplex stainless steel and other four major categories; steel chemical composition or classified by some of the characteristics of the elements in the steel, divided into chromium stainless steel, chrome-nickel stainless steel, chromium-nickel-molybdenum stainless steel and low carbon stainless steel, high molybdenum stainless steel, high purity stainless steel; divided into nitric acid-resistant stainless steel performance characteristics and use classification resistance to sulfuric acid stainless steel pitting corrosion resistance of stainless steel, stress corrosion resistance of stainless steel, high-strength stainless steel; classification features by steel, stainless steel divided into low, non-magnetic stainless steel, free cutting steel, superplastic stainless steel. The classification is classified according to the steel the characteristics of the organizational structure characteristics and chemical composition of the steel, and a combination of both methods. Generally divided martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel and precipitation hardened stainless steel or the like, or is divided into two categories of chromium stainless steel and nickel stainless steel. Very versatile, machinery and equipment, typical use: pulp and paper equipment used in heat exchangers, dyeing equipment, film processing equipment, piping, outside the coastal area buildings timber.

Stainless steel angle specifications: ∠ 25 * 25 - ∠ 150 * 150mm commonly used stainless steel angle Material: 201,202,301,304,316
Stainless steel angle commonly known as stainless steel angle iron (201 304 316L), on both sides of each other vertically angulated long steel. There are equilateral angle and unequal angle of the points. Equilateral angle width equal to the two sides. Its specifications to the edge, edge width × width × thickness of a few millimeters. As "∠ 30 × 30 × 3", i.e. the side width of 30 mm, the edge thickness of 3 mm edge angle. Can also be used to model, model is the edge of a wide number of centimeters of stainless steel angle according to the structure of the different needs of various force member, also can be used for connections between components. Widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnace, reaction tower, container frame and warehouse shelves, etc..
