Tensile Strength

Tensile strength refers to the maximum tensile stress that a material can withstand during a tensile test, typically measured in megapascals (MPa) or pounds per square inch (psi). In foreign trade, this term is commonly found in specifications, quality inspection reports, and contractual technical clauses for products such as metals, plastics, rubber, and textiles, and is used to measure the mechanical properties of materials. Usage scenarios include: customers requesting material certificates, suppliers specifying product performance in quotations, and inspections verifying compliance with standards. Notes: Different national or industry standards (such as ASTM, ISO, GB) may use different test methods, so values may not be directly comparable; tensile strength is different from yield strength—the former is the maximum stress before fracture, while the latter is the stress at which permanent deformation occurs; in addition, tensile strength should be distinguished from tear strength, compressive strength, and other terms. Foreign trade professionals should ensure that tensile strength indicators in contracts are listed together with the test standard to avoid quality disputes caused by differences in standards.
