The bending strength of reaction-sintered silicon carbide beams is calculated based on 250 MPa, with a 5-fold safety factor. The bearing capacity is determined for a length of 1 meter. When the product length is L, the bearing capacity can be calculated using the following formulas:
This bearing capacity applies to temperatures below 1380℃.
