Stainless steel is the abbreviation of stainless acid-resistant steel, which is an iron-based alloy.
Tensile strength? σb？ (MPa) ≥520
Hardness: ≤ 187HB
Typical use:
Stainless steel is widely used in the construction industry to keep the original appearance of buildings for a long time. Such as roofs and side walls of industrial buildings. In these applications, the owner's construction cost may be more important than beauty, and the effect of using 304 stainless steel in dry indoor environment is quite good. However, 3 16 stainless steel is best used in industrial or marine atmosphere with severe corrosiveness. Some design standards include 304 and 3 16 stainless steel. Pure silver is a simple metal with much lower strength than stainless steel.
Tensile strength? σb？ (MPa)≥ 180
Hardness: ≤25HB
Typical use:
Besides being used as currency and ornament, silver is mainly used in industry because of its good conductivity. Good reflectivity, silver is the best inner coating in the production of hot water bottle liner; Corrosion resistance, silver is an indispensable raw material for electroplating. Because the hardness of silver is too low, even the decorations are made of 925 silver instead of pure silver.
