Second best known austenitic grade. Mo increases the corrosion resistance. 1.4404 X2CrNiMo17-12-2 316L < 0.030 17.5 2.25 11.5 NS: 1400 Same as above but not susceptible to intergranular corrosion thanks to a lower C content. 1.4571 X6CrNiMoTi17-12-2 316Ti < 0.08 17.5 2.25 12 Ti: 5×C ≤ 0.70
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.
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
SAE 316L grade stainless steel, sometimes referred to as A4 stainless steel or marine grade stainless steel, is the second most common austenitic stainless steel after 304/A2 stainless steel. Its primary alloying constituents after iron , are chromium (between 16–18%), nickel (10–12%) and molybdenum (2–3%), up to 2% manganese , [ 1 ] with ...

The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than 1 / 4 inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
M designates common V threads (like for instance metric threads); Sq designates square threads; Tr designates trapezoidal threads; The shank length is not always the same at the thread length, which is the case if the insert has a threadless portion (sub-shank)
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1 ⁄ 2 to 1 + 1 ⁄ 2 inches (13 to 38 mm) in diameter.
