Silicon (Si): 1. enhances ductility; 2. increases tensile strength; 3. removes oxygen from molten metal by separating oxidation and vaporization.
Sulfur (S): small amounts can improve machinability.
Tungsten (W): Increase strength, hardness and toughness.
Vanadium (V): Increases strength, hardness and shock resistance.
The total heat transfer coefficient of a metal depends on other factors in addition to the thermal conductivity of the metal. In most cases, the film heat dissipation coefficient, the rust skin and the surface condition of the metal. Stainless steel can maintain a neat surface, so it is better than other metals with a higher thermal conductivity in heat transfer. Liaocheng Sandeli stainless steel provides eight, the technical standards of stainless steel plate stainless steel plate corrosion resistance, bending process performance and welded parts toughness, as well as the welded parts of the stamping process excellent performance of high-strength stainless steel plate and its manufacturing method. Specifically, it contains C: 0.02% or less, N: 0.02% or less, Cr: 11% or more less than 17%, the appropriate content of Si, Mn, P, S, Al, Ni, and meet 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, 0.006 ≤ C N ≤ 0.030 stainless steel plate heated to 850 ~ 1250 ℃, and then heat treatment with a cooling rate of more than 1 ℃ / s cooling. This can become a high strength stainless steel plate containing more than 12% volume fraction of martensite organization, more than 730 MPa of high strength, corrosion resistance and bending processability, and excellent toughness in the heat-affected zone of welding. Then use the Mo, B, etc., can significantly improve the welded part of the stamping process performance.
