Steel pipe network teach you how to distinguish between stainless steel pipe model

304 Stainless Steel Tube full name SUS304 stainless steel tube SUS304 stainless steel tube belongs to the American brand stainless steel material, the domestic brand equivalent to 0Cr19Ni9 stainless steel tube, usually with 0Cr18Ni9 instead.
201 Series - Chromium-Nickel-Manganese Austenitic Stainless Steel Series 300 - Chromium-Nickel Austenitic Stainless Steel 301 - Good ductility for use in forming products. It can also be hardened by mechanical processing. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel.
302—Corrosion resistance is the same as 304. The strength is better due to the relatively high carbon content.
303 - It is easier to cut than 304 by adding a small amount of sulfur and phosphorus.
304—Universal model; that is, 18/8 stainless steel. The GB grade is 0Cr18Ni9.
309 - better temperature resistance than 304.
316—Since 304, the second most widely used steel grade, mainly used in the food industry and surgical equipment, is the addition of molybdenum to obtain a special structure that resists corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery devices. 18/10 grade stainless steel also generally meets this application level. [1]
Model 321 - Other properties are similar to 304 except that the addition of titanium reduces the risk of corrosion of the weld material.
Series 400 - Ferritic and Martensitic Stainless Steel 408 - Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409 - The cheapest model (British and American), commonly used as automotive exhaust pipe, is a ferritic stainless steel (chrome steel).
410—Martensite (high strength chrome steel), good wear resistance, poor corrosion resistance.
416 - Added sulfur improves the material's processability.
420—"Blade-grade" martensitic steel, similar to Brinell's high chromium steel, the earliest stainless steel. Also used for surgical tools, can do very bright.
430—ferritic stainless steel, decorative, for example for automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
440—High-strength cutting tool steel with slightly higher carbon content. After appropriate heat treatment, it can obtain higher yield strength, and the hardness can reach 58HRC, which is among the hardest stainless steels. The most common application example is the "razor blade." There are three commonly used models: 440A, 440B, 440C, in addition to 440F (easy processing type).
Series 500 - Heat-resistant chromium alloy steel.
Series 600 - martensitic precipitation hardened stainless steel.
630—The most commonly used precipitation-hardening stainless steel model, also commonly called 17-4; 17% Cr, 4% Ni.

Stainless steel plate surface smooth, high plasticity, toughness and mechanical strength, acid, alkaline gas, solution and other media corrosion resistance. It is an alloy steel that does not rust easily, but not absolutely. Stainless steel plate refers to the corrosion resistance of weak medium such as atmosphere, steam and water steel plate, and acid resistant steel plate refers to the corrosion resistance of chemical etched medium such as acid, alkali, salt steel plate.

According to the structure is divided into austenitic stainless steel plate, martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, and austenitic ferritic biphase stainless steel plate and so on four categories? According to the main chemical composition of the steel plate or some characteristic elements in the steel plate to be classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate. According to the performance characteristics and use of steel plate classification, is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, no magnetic stainless steel plate, easy cutting stainless steel plate, super plastic stainless steel plate. Currently, the commonly used classification method is according to the structural characteristics of steel plate and steel plate chemical composition characteristics and the combination of the two methods. Generally divided into martensitic stainless steel plate, ferritic stainless steel plate, austenitic stainless steel plate, duplex stainless steel plate and precipitation hardening type stainless steel plate or divided into chromium stainless steel plate and nickel stainless steel plate two categories.

Typical uses: pulp and paper equipment heat exchanger, mechanical equipment, dyeing equipment, film washing equipment, pipelines, coastal area building external materials, etc.
