City issued a total of Metal Materials Co., Ltd. specializes in the wholesale all kinds of 304 stainless steel with 304 stainless steel coil 0.3mm 304 stainless steel with mechanical properties: 1. The yield strength (σ0.2): make a permanent residual plastic deformation is equal to a certain value (usually stress 1Cr17 stainless steel with 0.2%) of the original length of time, known as the yield strength σ0.2. 2. Tensile strength (σb): material during the stretching, the fracture occurred from the start to the maximum stress value attained. It indicates the size of the fracture resistance of steel. Pb material pulled before setting off to achieve maximum tensile stainless steel strip, Fo-sectional area of ??the specimen stamping stainless steel, the tensile strength σb = Pb / Fo (MPa). 3. elongation (δs): material fractured tensile stainless steel, the percentage of the length of the original sample length of the plastic elongation is called elongation or elongation. 4. Hardness: Hardness indicates that the material to resist a hard object pressed into the surface of its capabilities. It is one of the important performance metallic material. Generally, the higher the hardness, wear resistance, the better.
