API X70 Steel Based on the Theory of Strain Gradient . Mohammed Anazi and Hussein Zbib . Washington State University . School of Mechanical and Materials Engineering . Abstract . This work shows the results of a continuum model of deformation and damage for API X70 steel based on the strain gradient theory. API 5L Pipes for Pipelines Explained - ProjectmaterialsSep 20, 2017 · The yield strength of an API 5L pipe is specified with the number that follows the X in the material grade designation (in kilopounds per square inch i.e. KSI). So, for instance, an API 5L X52 pipe has a minimum yield strength of 52 KSI.
Feb 13, 2015 · Tensile deformation test. In order to evaluate mechanical properties of as-processed and annealed samples, uniaxial tensile deformation with a strain rate of 10 1 ns 1 at 300 K was applied Flexural Strength Testing of PlasticsFlexural Strength Testing of Plastics. The flexural strength of a material is defined as its ability to resist deformation under load. For materials that deform significantly but do not break, the load at yield, typically measured at 5% deformation/strain of the outer surface, is reported as the flexural strength or flexural yield strength. Issue No 15 - Grain Size and Material StrengthGrain Size and Material Strength (continued) Most metal manufacturers will attempt to keep grain size to a minimum when manufacturing materials for use in electrical connectors. A fine grain size will certainly improve the yield strength and stress relaxation resistance of the finished product.
Metric bolt grades and strength calculator to show proof strength, tensile strength, Vickers / Brinell hardness, minimum breaking torque and stress area of metric bolts and screws made of carbon steel and alloy steel with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.

PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements. Grades covered by this specification are A25, A, B and "X" Grades X42, X46, X52, X56, X60, X65, X70, and X80. The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe
