GB21456 Low Carbon Steel Standard Pans
1.Introduction
The standard pan is designed according to annex A, GB21456-2014, it is applied to evaluate the energy efficiency and energy efficiency grades. The pan and the lid are made of Q235 having a maximum carbon content of 0.08%, and the thickness of the lid (t) is 1mm, the bottom of the pan can not convex outward, and the maximum concavity at the bottom is 0.6% times the effective diameter. The surface of the pan and the lid should be smooth and polished to prevent rust.
