Study Stainless Steel Technical Made Simple: A Step-by-Step Guide
Do you know what should know when purchasing stainless steel materials? What is the Stainless Steel Technical?
If you're a steel industry insiders like me , you probably need to know those stainless steel technical.
Stainless steel technical knowledge directly affects the purchase of stainless steel or the use of stainless steel materials. From articles and videos to information icons, stainless steel buyers talk about finding the most strategic way to purchase stainless steel materials.

Stainless teel Mechanical Properties
Mpa Yield Strength
Mpa Yield Strength: Refers to the stress that the material bears when yielding occurs. The unit is MPa. It is an intrinsic property of the material and represents the critical stress value of material yielding. It is often used to determine the maximum allowable load of mechanical parts.
Mpa Tensile Strength
The tensile strength is the critical value for the transition of stainless steel from uniform plastic deformation to local concentrated plastic deformation, and it is also the maximum bearing capacity under static tension conditions. In short, the essence is the maximum uniform plastic deformation resistance of stainless steel, the symbol is Rm, and the unit is MPa.
For example, no matter how large the cross-sectional area of a 304 stainless steel rod is, its tensile strength is only related to the 304 stainless steel material and has nothing to do with the cross-sectional area.
The unit conversion is as follows:
Stainless steel Strip Thickness Tolerance Range
Tolerance refers to the amount of change in thickness that meets the nominal size.
The thinner the stainless steel, the smaller the tolerance. For example, it is more common for a hot-rolled coil with a thickness of 3.0mm to be pressed into a thickness of 1.2mm, which may be plus or minus 2-4, but when pressed to 0.3, the thickness is only 1-2 C, because The thinner you press, the more processes and the less negative the thickness difference.

Comparison Table of Tensile Strength and Hardness
Hardness test is the simplest and most feasible test method in the mechanical performance tests. In order to replace certain mechanical performance tests with hardness tests, a more accurate conversion relationship between hardness and strength is required in production. Practice has proved that between various hardness values of metal materials, there is an approximate corresponding relationship between the hardness value and the strength value.
Because the hardness value is determined by the initial plastic deformation resistance and the continued plastic deformation resistance, the higher the strength of the material, the higher the plastic deformation resistance and the higher the hardness value.
