Angle steel stainless steel
Product Introduction
1. Geometric Dimensions and Tolerances
| Parameter | Symbol | Unit | Description |
|---|---|---|---|
| Leg Width | b | mm | The length of the two right – angled sides of the angle steel. For equal – leg angle steel, the two leg widths are equal; for unequal – leg angle steel, they are not equal. |
| Leg Thickness | t | mm | The thickness of the right – angled side. |
| Sectional Area | A | cm2 | The total area of the cross – section of the angle steel, which can be calculated according to the leg width and leg thickness. |
| Theoretical Weight | W | kg/m | Calculated according to the formula, it represents the weight per unit length of the angle steel. |
| Dimensional Tolerance of Leg Width | – | mm | For example, when the leg width is 20mm, the tolerance is ±1.0mm; when the leg width is 25 – 50mm, the tolerance is ±0.6mm. |
| Dimensional Tolerance of Leg Thickness | – | mm | Such as when the leg thickness is 3 – 6mm, the tolerance is ±0.4 – ±0.6mm. |
| Squareness | – | ° | It should be 90°±2°. |
| Warpage | – | mm/m | ≤3mm/m. |
2. Mechanical Properties
| Parameter | Symbol | Unit | Description |
|---|---|---|---|
| Tensile Strength | Rm | MPa | The maximum stress that the material can withstand during the tensile process. |
| Yield Strength | ReL or Rp0.2 | MPa | The stress at which the material begins to yield plastic deformation. |
| Elongation | A | % | The percentage of the increase in length after the material is broken during the tensile test compared to the original length. |
| Hardness | – | HB or HRB | Used to measure the hardness of the material, such as Brinell hardness (HB) or Rockwell hardness (HRB). |
