Briefly introduce the tensile strength of stainless steel strip
source：www.peinv.com.cn | Release time：2025年08月26日1. The numerical range varies greatly and is strongly related to the material/processing state
The tensile strength of stainless steel strips with different models and processing techniques varies significantly: for example, the common 304 stainless steel strip (annealed, soft) has a tensile strength of about 520MPa, which can be increased to over 800MPa after cold work hardening; The tensile strength of high-strength 316L stainless steel strip (cold working state) can reach 700-900MPa, and the martensitic stainless steel strip (such as 410) specially used for stress scenarios can even exceed 1000MPa in tensile strength.
2. Determining the usage scenario is the core basis for selection
The tensile strength directly affects the applicable scenarios of stainless steel strips: Soft strips with low tensile strength (such as annealed 304) are suitable for scenarios that require bending and stamping (such as kitchen countertop edge sealing and home appliance decorative parts); High tensile strength hardened bands (such as cold worked 316) are used for load-bearing components (such as mechanical transmission belts, electronic device fastening belts) to avoid being pulled apart or deformed during use.
3. Unified testing standards and referenceability of results
The industry usually tests according to standards such as GB/T 228.1 (national standard) or ASTM A370 (American standard): the tensile strength is obtained by slowly applying tension through a tensile testing machine, recording the larger load before fracture, and dividing it by the original cross-sectional area of the sample. The result can be directly used for product quality judgment and selection comparison.
