The ASME steel grade SA533 GrB CL2 corresponding to 16MnD5 is similar in function to 35CrMo steel. Because of the increased carbon and chromium content, its strength and hardenability are better than 35CrMo steel. After quenching and tempering, it has higher fatigue strength and repeated impact resistance, excellent low temperature impact toughness, no obvious temper brittleness, generally used after quenching and tempering, can be used to replace quenched and tempered steel with higher nickel content.
