Stainless steel tube components can be divided into the Cr (400 series), Cr-Ni system (300 series), Cr - Mn-Ni (200 series) and precipitation hardening system (600 series). 200 series - chromium - nickel - manganese austenitic stainless steel 300 series - chromium - nickel austenitic stainless steel, 301 ----- scalability for molding products. Machining allows them to quickly harden. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. ,302 ----- Corrosion resistance of 304, thus the carbon content is relatively higher strength and better. 30 ,303 ----- by adding a small amount of sulfur, phosphorus than 304 easier cutting. Four, 304 ----- 18/8 stainless steel. GB grades 0Cr18Ni9. 309 - better temperature resistance compared to 304. 5, 316 ----- Following the 304 after the second to get the most widely used steel, mainly used in the food industry, pharmaceutical industry, and surgical equipment, add molybdenum element to obtain the special structure of an anti-corrosion . Thus better resistance to chloride corrosion compared to the 304 stainless steel tube for marine steel. SS316 is often used in nuclear fuel recovery. 18/10 stainless steel pipe is usually to meet this level. Stainless steel bucket model 321, [1] - In addition to the added titanium elements to reduce the risk of corrosion of materials, weld performance similar to the 304. 400 Series - ferritic and martensitic stainless steel. 408 - good heat resistance, and weak resistance to corrosion, 11% Cr, 8% Ni. 409 - the cheapest model (BAR), usually as an automobile exhaust pipe, is a ferritic stainless steel (chrome steel). 410 - martensite (high-strength chromium steel), good wear resistance, corrosion resistance is poor. 416 - add sulfur to improve the processing properties of the material. 420 - "cutting tool grade martensitic steels, similar Brinell this kind of high-chromium steel of the earliest stainless steel. Also used in surgical tools, can do very bright. 430 - ferritic stainless steel, decorative, such as for car accessories. Good formability, heat resistance and corrosion resistance worse. 440 - high-strength cutting tool steel, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength, hardness can achieve 58HRC, belong to the most hard stainless steel column. The most common application example is the "razor blade". There are three commonly used models: 440A, 440B, 440C, in addition to 440F (easy processing). 500 series - heat-resistant chromium alloy steel. 600 Series - martensitic precipitation hardening stainless steel tube. 630 - the most commonly used precipitation hardening stainless steel models, usually called 17-4; 17% Cr, 4% Ni.
