There is no relevant information about "SGS 439 17 - 4 pH Nickel Alloy Stainless Steel Sheet/Plate". You might be referring to "17 - 4PH" stainless - steel sheet/plate, which is a martensitic precipitation - hardening stainless steel with the following characteristics1:

 

 

Physical properties: In the solution - annealed state, the density is 7.75g/cm³, the melting point range is 1404 - 1440°C, the specific heat is 460J/kg - °C at 20°C, the elastic modulus is 196GPa, and the thermal conductivity is 18.3W/m - °C at 100°C.

Mechanical properties: The mechanical properties can be significantly improved through heat treatment. For example, after aging treatment at 480°C, the tensile strength is ≥1310MPa, the yield strength is ≥1180MPa, the elongation is ≥10%, the reduction of area is ≥40%, and the hardness is ≥375HB and ≥40HRC.

Heat - treatment process: It mainly includes two stages, solution treatment and aging treatment. Solution treatment is usually carried out at 1020 - 1060°C, followed by rapid cooling, generally using water - cooling. Aging treatment is carried out at different temperatures (such as 480°C, 550°C, 580°C, 620°C) to meet different performance requirements.

Features and advantages: It has excellent mechanical properties, outstanding corrosion resistance, and superior processability, and can be used for machining, welding, and forming.

Application fields: It is widely used in aerospace, chemical equipment, energy industry, medical equipment, offshore platforms, food industry, pulp and paper industry and other fields.
