304 316 stainless steel pipe

详情

Stainless steel pipe is a hollow long round steel, mainly widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentsStainless steel tube components can be divided into the Cr (**0 series), Cr-Ni system (**0 series), Cr - Mn-Ni (**0 series) and precipitation hardening system (**0 series).**0 series - chromium - nickel - manganese austenitic stainless steel **0 series - chromium - nickel austenitic stainless steel ,**1 ****- scalability for molding products.Machining allows them to quickly harden.Good weldability.Abrasion resistance and fatigue strength than **4 stainless steel.,**2 ****- Corrosion resistance of **4, thus the carbon content is relatively higher strength and better.*0 ,**3 ****- by adding a small amount of sulfur, phosphorus than **4 easier cutting.Four, **4 ****- *8/8 stainless steel.GB grades 0Cr*8Ni9.**9 - better temperature resistance compared to **4.5, **6 ****- Following the **4 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 **4 stainless steel tube for marine steel.SS**6 is often used in nuclear fuel recovery.*8/*0 stainless steel pipe is usually to meet this level.Stainless steel bucket model **1, [1] - In addition to the added titanium elements to reduce the risk of corrosion of materials, weld performance similar to the **4.**0 Series - ferritic and martensitic stainless steel.**8 - good heat resistance, and weak resistance to corrosion, *1% Cr, 8% Ni.**9 - the cheapest model (BAR), usually as an automobile exhaust pipe, is a ferritic stainless steel (chrome steel).**0 - martensite (high-strength chromium steel), good wear resistance, corrosion resistance is poor.**6 - add sulfur to improve the processing properties of the material.**0 - "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.**0 - ferritic stainless steel, decorative, such as for car accessories.Good formability, heat resistance and corrosion resistance worse.**0 - high-strength cutting tool steel, carbon is slightly higher, after appropriate heat treatment to obtain a higher yield strength, hardness can achieve *8HRC, belong to the most hard stainless steel column.The most common application example is the "razor blade".There are three commonly used models: **0A, **0B, **0C, in addition to **0F (easy processing).**0 series - heat-resistant chromium alloy steel.**0 Series - martensitic precipitation hardening stainless steel tube.**0 - the most commonly used precipitation hardening stainless steel models, usually called ***4; *7% Cr, 4% Ni., such as industrial pipeline and mechanical structure parts.
