300 series stainless steels are classified as austenitic with approximately 18% to 30% chromium and 6% to 20% nickel as their major alloying additions. These grades of stainless steels are easily welded and machined but hardened only by cold working methods. 300 series stainless steel has good corrosion resistance while maintaining their ABOUT STAINLESS STEEL SS304 SS316 SS310 SS317L SS321 Austenitic stainless steels can be further subdivided into two sub-groups, 200 series and 300 series:200 series are chromium-manganese-nickel alloys that maximize the use of manganese and nitrogen to minimize the use of nickel.
In the AISI classification they are identified as the 300 series and the various grades of this family differ mainly in their nickel content; the basic composition of austenitic stainless steel is 18% chrome and 8% nickel, codified as AISI 304, or 18/8, while adding a percentage of 2-3% of molybdenum ensures better corrosion resistance and Austenitic Stainless Steel - an overview ScienceDirect Austenitic stainless steels are among the most widely used types of stainless steel. The most commonly used grades are the American Iron and Steel Institute (AISI) 300 series of alloys. Austenitic Stainless Steels - ASM Internationalhigher-nickel 300 series as the de facto standard when the more cost-efficient high-manganese 200 series is the logical basic grade. The rele-vant types of austenitic alloys can nonetheless be rationalized with this diagram. As chromium is added, oxidation resistance and
The most common austenitic alloys are iron-chromium-nickel steels and are frequently referred to as 300 series stainless. The best known austenitic Stainless Steel grades are 304/L & 316/L with other well-known grades such as 321 and 310. These grades contain minimum 16% chromium and 6% nickel commonly referred as 18/8 stainless (grade 304). Machinability of Stainless Steel - Machining DoctorMachinability of Austenitic Stainless-Steel 300 series (303/304/316) Main Problems:High cutting forces. Heat. Build up Edge Workpiece material sticking to the cutting edge. Notch Wear (Vg) High wear developing at the depth of cut line. Higher Nickel and Molybdenum content decrease machinability. Austenitic Stainless Steel - Information About 300 Series Sep 14, 2020 · Continuing our series on stainless steels, this video is focused on the most commercially popular Austenitic types or grades. In this video we will discuss 303 or 303S, 303 Se, 304, 304L, 316 , 317 and 317L. From our introduction to stainless steels video you know that Chrome is primarily what makes these stainless steels corrosion
