2507 Stainless Steel Sheet

The overall thermal conductivity of metals, in addition to depending on the thermal conductivity of the metal itself, is also influenced by other factors. In most cases, these include the film heat transfer coefficient, rust scale, and the surface condition of the metal. Stainless steel maintains a clean surface, thus it has better thermal conductivity than other metals with higher thermal conductivity. Liaocheng Sandeli Stainless Steel offers technical standards for stainless steel sheets, including their corrosion resistance, bending processing properties, and toughness at welding sites, as well as the excellent stamping processing properties of high-strength stainless steel sheets and their manufacturing methods. Specifically, stainless steel sheets containing less than 0.02% C, less than 0.02% N, more than 11% and less than 17% Cr, appropriate amounts of Si, Mn, P, S, Al, and Ni, and meeting the specifications of 12≤Cr Mo 1.5Si≤17, 1≤Ni 30(C N) 0.5(Mn Cu)≤4, Cr 0.5(Ni Cu) 3.3Mo≥16.0, and 0.006≤C N≤0.030 are heated to 850～1250°C and then heat-treated with a cooling rate of more than 1°C/s. This results in high-strength stainless steel sheets with more than 12% martensite volume fraction, over 730MPa in strength, excellent corrosion resistance, bending processing properties, and toughness in the heat-affected zone. By utilizing Mo, B, and other elements, the stamping processing properties of the welding site can be significantly improved.

Oxygen-acetylene flames cannot cut stainless steel plates because stainless steel is not easily oxidized.
