Stainless steel water tank, or water tank for drinking water, or water tank of food grade, or water tank of SUS304/316, they are available in two connection types: argon arc welding and bolted. Raw materials can be SS304/2B and SS316L. Compared with other material water tank, stainless steel water tank is featured with anti-corrosion, easy installation, easy cleaning, high temperature resistance, etc, and it is widely used to store drinking water.
The provided table summarizes the physical properties of a stainless steel water tank. The properties tested include yield strength, tensile strength, elongation, and hardness. The results are compared against standard requirements to assess the quality of the tank material.
| Physical Properties | Standard Requirement | Result |
|---|---|---|
| Yield Strength (MPa) | ≥515 MPa | 695 MPa |
| Tensile Strength (MPa) | ≥205 MPa | 309 MPa |
| Elongation | ≥40 | 54% |
| Hardness | ≤921HRBS | 85HRBS |
