GB/T150.2 Allowable stress table for materials
Thread Content
I didn’t attend the standard promotion meeting – what does a thick, solid black line on the allowable stress table mean? The allowable stress for the stainless steel material S30408 has two values; how should this allowable stress be chosen?
1. In the allowable stress table specified in GB150.2-2011, the allowable stress values on the right side of the thick solid line are determined by the high-temperature endurance strength limit of the steel material after 100,000 hours of exposure. 2. There are notes at the bottom of the table for cases with two rows of values; one set of values is intended for use with flanges where slight deformation is permissible
