![]() ![]() Instron's Industrial Series offers test frames suitable for testing machined stainless steel rounds (300kN) all the way up to thick wall tubular products (2000kN). Total Elongation – A measurement of the percentage increase in length after failureīecause ASTM A370 testing is conducted on such a wide variety of steel products and specimen geometries, system force requirements can differ greatly.Reduction of Area - A measurement of the ductility of a material.Tensile Strength - The maximum force or stress that a material is capable of sustaining.Yield Strength - The stress at which a material becomes permanently deformed.Modulus of Elasticity – A measurement of a material's resistance to elastic deformation.The most commonly measured properties are the following: Though ASTM A370 references different test types, tensile testing is the primary focus. It is important to note that although the annexed sections are supplementary to the general section of the standard, the product standard often prevails in the event of conflict. A370 differs from E8 in that it further defines the specimen characteristics of steels specific to several different product types. These products discuss the testing of bar, tube, fasteners, and round wire, and are included in the annexes to ASTM A370 along with some procedural clarification. ASTM A370 shares the same testing equipment and test methods as another major metals testing standard, ASTM E8. ![]()
