18/8 stainless steel refers to the chemical composition of stainless steel containing 18% chromium (Cr) and 8% nickel (Ni). Standard 18-8 stainless steel includes SS 304, 304L, 304N, 304LN, 304H, non-standard 18-8 grade includes AISI 301, 302, 301L, 301LN, 302B, etc. 18/8 steel is the most widely used material, has excellent corrosion resistance in mild environments, and has good weldability and
Fasteners Bolt Grades, Strength & MaterialsFerritic grades of stainless include:430 and 430F. Below are some of the many bolt grades of stainless steel that we carry. 18-8 Stainless Steel:(18% Chrome, 8% Nickel, .08% Maximum Carbon) - 18-8 Stainless refers to 300 series stainless steel. 303 and 304 Stainless are the most commonly listed grades, the standard grade for stainless fasteners.
Jul 01, 2020 · Grade 316 this grade of stainless steel fastener is required in extreme environments. The carbon content is set to 0.8% while the nickel content is increased. These fasteners are non-magnetic, can only be hardened by cold working and are austenitic.
Identification Tests for Stainless SteelsStainless Steel Pipes - Allowable Pressure - Allowable pressure for standard seamless A312-TP316/316L stainless steel pipes - temperatures 100 o F to 750 o F Stainless Steel Pipes - Comparing of American and European Standards - Comparing American - US - and European - German, British (UK) and Swedish - stainless steel pipe standards
Jul 22, 2010 · Hardest and strongest are not the same thing. 17-4 PH is an excellent choice for strength, but 440C will have the highest hardness. 440c is a martensitic stainless steel (magnetic) that is used for bearing applications, so it has high surface hardness, but low ductility and fracture toughness.
Free-machining bar grade. 420. Higher hardness martensitic grade for cutlery, cutting tools and dies. 431. High hardness and toughness grade, primarily for shafting. 440A, 440B, 440C. Very high hardness grades used in cutting tools. Precipitation Hardening Stainless Steel. 630 (17-4PH) High strength shafting grade. Complete Set of Datasheets

What Are the Strongest & Hardest Metals Known to Sep 20, 2017 · As for hardness, chromium is the hardest known metal. While the hardest known mineral in the universe is diamond, the honor of the hardest metal goes to chromium. Chromium is used in the well-known alloy stainless steel to make it harder. Tajzheal on May 27, 2020:As for hardness, chromium is the hardest known metal.
Brinell hardness of ferritic stainless steel Grade 430 is approximately 180 MPa. In materials science, hardness is the ability to withstand surface indentation (localized plastic deformation) and scratching.Stainless steel grade chart - Atlas SteelsNote 2:Hardness specication limits given are HRB = Rockwell B scale, HRC = Rockwell C scale, HB = Brinell Hardness. Note 3:3CR12 generally conforms with both ASTM A240 grade S41003 and with EN 10088 Parts 1 and 2, grade 1.4003. Properties quoted are from EN 10088.2.
