ASTM A312 TP304 Austenitic 316l Stainless Steel Tube Seamless Mechanical Tubing
Specifications:
300 series: chromium nickel austenitic stainless steel
Model 301: good ductility, used for forming products. It can be quickly hardened by machining. Good welding. Abrasion resistance and fatigue strength than 304 stainless steel products, such as: spring, steel, wheel cover.
Model 302: 304 with corrosion resistance, due to the relatively high carbon intensity.
Model 303: by adding a small amount of sulfur and phosphorus to make it more than 304 of the cutting process.
Model 304: general model; 18/8 stainless steel. Products such as: corrosion resistant containers, tableware, furniture, railings, medical equipment, a number of mobile phone borders. Standard components are 18% chromium plus 8% nickel. Stainless steel, which has no magnetism and can not be changed by heat treatment method to change the microstructure of the metallographic structure.
Type 304 L: and 304 same characteristics, but low carbon so more corrosion resistant, easy to heat treatment, but poor mechanical for welding and is not easy to heat treatment products.
304 types of N: 304 with the same characteristics, is a kind of nitrogen stainless steel, nitrogen addition is to increase the strength of steel.
Model 309: compared with 304 have better temperature resistance.
Types of 309 s: with large amounts of chromium, nickel, therefore, thermal stability, oxidation stability good, products such as: heat exchanger, boiler components, jet engine.
Model 310: S containing the highest amount of chromium and nickel, so the heat resistance, oxidation resistance, the optimal heat exchanger boiler components, electrical equipment.
316: following the 304, the second most widely used of steel, mainly for the food industry and surgical equipment, adding Mo to obtain a special corrosion resistant structure. As a result of the more than 304 of its resistance to chloride corrosion and thus also for the "ship" to use. SS316 is usually used for nuclear fuel recovery devices. Grade 18/10 stainless steel is generally in line with the application level. Specialty in chemistry, environment, etc. the corrosion of ship assembly, building materials.
Types of 316 L: low carbon so more corrosion resistant, easy to heat treatment, products such as: chemical processing equipment, nuclear power generators, the coolant reservoir worse.
Model 321: not only because of the added element titanium reduces the risk of weld material corrosion performance than other similar to 304, suitable for welding, brewing equipment, steam pipe, aviation parts.
Model 347: adding stabilized element niobium, suitable for welding aviation equipment parts and chemical equipment.

Description:
This kind of steel except for corrosion resistance to oxidizing acid medium, if containing Mo and Cu elements can resistance to sulfuric acid, phosphoric acid and formic acid, acetic acid, urea and other corrosion. If the carbon content in the steel is less than 0.03% or Ti and Ni, the corrosion resistance of the steel can be improved significantly. High silicon austenitic stainless steel has good corrosion resistance to concentrated nitric acid. The comprehensive and good comprehensive properties of austenitic stainless steel, widely used in all walks of life.
