1. What is a stainless steel sheet/plate?
Stainless steel plates offer strong corrosion resistance, processability, and aesthetic qualities. They are made of stainless steel alloys like chromium, nickel, and molybdenum. The following 4 categories can be used to categorize stainless steel plates based on distinct manufacturing techniques and material compositions:
Ferritic stainless steel sheet/plate: that is, stainless steel plate containing higher ferrite, the common ones are 0Cr18Ni9 and 1Cr18Ni9Ti.
Austenitic stainless steel sheet/plate: that is, stainless steel plate containing higher austenite, the common ones are 301, 304, 321, 316, 310, etc.
Ferrite-austenitic stainless steel sheet/plate: a stainless steel plate containing both ferrite and austenite. Common ones include 0Cr17Ni12Mo2, 0Cr13Ni4Mo, SAF2205, etc.
4. Martensitic stainless steel sheet/plate: that is, stainless steel plate containing higher martensite, the common ones are 17-4PH (UNS S17400), 15-5PH, etc.

3. Mechanical properties of stainless steel sheet/plate
Yield point (σs)
When the steel or sample is stretched, when the stress exceeds the elastic limit, even if the stress no longer increases, the steel or sample continues to undergo significant plastic deformation. This phenomenon is called yielding, and the minimum stress value when yielding occurs is for the yield point. Assume Ps is the external force at the yield point s, Fo is the cross-sectional area of the sample, and then the yield point σs = Ps/Fo (MPa).
Yield strength (σ0.2)
The yield point of some metal materials is extremely unclear and difficult to measure. Therefore, in order to measure the yield characteristics of the material, the stress when the permanent residual plastic deformation is equal to a certain value (usually 0.2% of the original length) is specified, which is called the condition. Yield strength or simply yield strength σ0.2.
Tensile strength (σb)
The maximum stress value reached by the material from the beginning to the time of fracture during the stretching process. It indicates the steel's ability to resist fracture. Corresponding to tensile strength are compressive strength, flexural strength, etc. Assuming that Pb is the maximum tensile force reached before the material is broken, Fo is the cross-sectional area of the sample, then the tensile strength σb = Pb/Fo (MPa).
Elongation (δs)
After the material is pulled apart, the percentage of its plastic elongation length to the original sample length is called elongation or elongation.
Yield-strength ratio (σs/σb)
The ratio of the yield point (yield strength) of a material to its tensile strength is called the yield ratio. The larger the yield-strength ratio, the higher the reliability of structural parts. Generally, the yield-strength ratio of carbon steel is 0.6-0.65, and that of low-alloy structural steel is 0.65-0.75. Alloy structural steel is 0.84-0.86.
Hardness
Hardness indicates a material's ability to resist hard objects pressing into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell hardness, and Vickers hardness.
