SAE steel grades - Wikipedia

The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly.


Duplex Stainless Steel. In duplex stainless steel, it has a 50% austenite and 50% ferrite microstructure. It was manufactured to give welders a corrosion resistant, higher strength option as an alternative to 300 series austenitic stainless products.


Socket stainless steel flange commonly used materials include: 201 304 316 304L 316. It is forged from stainless steel flange with welding thread. It can also be formed by thread connection or welding. It is composed of a pair of threaded flange, a gasket and several bolts and nuts. The gasket is placed between the two flange sealing surfaces.


Most offer good weldability and formability in comparison to other families of steel. Some are offer improved corrosion resistance. Chloride-resistant stainless steels are especially popular in offshore use. Common duplex alloys include are 318L, LDX 2101, LDX 2304, 2507 and 4501 (Also known as 25CR superduplex) grades.



SS321 is an Austenitic Stainless steel having the nominal composition (wt. %) of this classification is 19.5 Cr, 9.5 Ni, with titanium (5 times the amount of Carbon) added. The titanium acts in the same way as niobium in Type 347 in reducing intergranular chromium carbide precipitation and thus increasing resistance to intergranular corrosion.


Classification. Stainless steels come in several types depending on their microstructure. Austenitic stainless steels: Contain at least 6 percent nickel and austenite—carbon-containing iron with a face-centered cubic structure—and have good corrosion resistance and high ductility (the ability of the material to bend without breaking).


Let's talk about the classification of stainless steel and development. Stainless steel accordance with the organizational category (heated to high temperature air cooling after organization) : Be classified as ferritic stainless steel、 austenitic stainless steel、 duplex stainless steel、and precipitation hardened stainless steel.


largest stainless steel family in terms of alloys and usage. They include these grades: • Iron-chromium-nickel grades corresponding to both standard AISI 300-series alloys and modified versions of these alloys. Such al-loys, which are based on type 304 (18-8) stainless steel, as shown in Fig. 1, generally contain 16 to 26% Cr, 10 to 22% Ni, and


Steel is graded as a way of classification and is often categorized into four groups —Carbon, Alloy, Stainless, and Tool. Carbon Steels only contain trace amounts of elements besides carbon and iron. This group is the most common, accounting for 90% of steel production. Carbon Steel is divided into three subgroups depending on the amount of ...


stainless steel classification provides a comprehensive and comprehensive pathway for students to see progress after the end of each module. With a team of extremely dedicated and quality lecturers, stainless steel classification will not only be a place to share knowledge but also to help students get inspired to explore and discover many creative ideas from themselves.


Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are: 1. Metallurgical Structure. 2. The AISI numbering system: namely 200, …
