Webb2 maj 2024 · It is common for most engineers to specify a minimum operating temperature of -20°C, as it is easy and cost-effective. However, it is more than likely that many pieces of equipment will be used at lower temperatures than that. Switching to a quenched and tempered steel can give you a crane that is able to operate in – 40°C. WebbNiobium-bearing steels (15GB and 15G2FB) have the lowest values of NDTT, vandium-and nitrogen-bearing steels (15GAF and 15G2AF) have somewhat higher values, and vanadium-bearing steels (15GF) have the highest values. falvey library website
