grade 8 vs stainless steel
Aug 22, 2016 · Stainless steel, known primarily for its corrosion resistance, is used in a wide variety of applications.The diverse range of grades allows it to accommodate various applications across many different industries. However, having so many grades requires the know-how to ASTM A194 Grade 8 Specification - Boltport Fasteners39 rows · Standard Specification for Carbon and Alloy Steel Nuts for Bolts for High Pressure or High
Grade 8 / Grade G. Grade 8 bolts have been hardened more than grade 5 bolts. Thus they are stronger and are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head. Grade G is roughly equivalent to Grade 8. Grade G nuts are used with Grade 8 Grade FastenalA general designation for the most common and popular stainless steel, (300 Series) referring to the 18% chromium and 8% nickel. It's strength has a range from the middle to low end of the grade scale. All 300 series stainless steel share the ratio of chromium to nickel with varying other elements improving different properties. High Tensile Steel vs Stainless Steel Bolts in Marine Jun 10, 2020 · A Summary. Notice the yield strength is higher in 304 stainless steel. Then let's think about what that means. "Yield Strength is the stress a material can withstand without permanent deformation or a point at which it will no longer return to its original dimensions (by 0.2% in length).
The term 18-8 is used interchangeable to characterize a series of different stainless steel grades, to include 304 and 305. The distinction between 18-8 and 304/305 is the small addition of Carbon added to its makeup and the percentage of elements used in its creation. 304 grades contain roughly 18% Chromium, 8% Nickel and a maximum of .08% carbon. Strength Specifications of Metric Threaded FastenersIn the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa. Strength Specifications of Stainless Steel Threaded Fasteners What Is the Difference Between Plain Grade 8 Bolt & Yellow According to K-T Bolt Manufacturing Inc., Grade 8 bolts "are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head." Unlike stainless steel, which is highly resistant to corrosion, steel, however reinforced, will oxidize over time and rust.
Jun 22, 2012 · Lastly, the actual steel grade used by manufacturers may vary but in most cases, a grade 8.8 fastener (self-colour, black-oxide or zinc plated) will be manufactured from a medium-alloy medium carbon steel, typically with 0.30 - 0.50 % Carbon and alloyed with other elements such as Molybdenum, Vanadium, Manganese and sometimes Boron or Cobalt in small quantities.Stainless or grade 8 bolts Pirate 4x4Dec 30, 2002 · The average tensile strength is in the range of 80,000 psi while the minimum for Grade 8 is 150,000. This means that it is important to use very low torque specs and avoid cranking on the bolt until it won't turn any farther. If a torque chart for stainless steel fasteners is not available, use the specs for a Grade 2 bolt
