VP 80 Steel

VP 80 Steel

Steel name: VP 80
Diagram No.: 1791
Chemical composition in weight %: 0.04% C, 0.25% Si, 12.00% Cr, 7.80% Ni, 1.50% Mo, 1.20% Al
Steel group: Plastic mould steels
Properties: No data
Applications: Moulds for Injection or extrusion of chlorinated thermoplastic polymers, such as PVC. Moulds that work or are storage in corrosion environments or wet conditions. Moulds for glass industry. Parts in which high strength and low distortion in heat treating are necessary. Other applications were high mechanical strength and high corrosion resistance are necessary.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Solution treating: the material is delivered in this condition. However, if hardness decrease of aged parts is necessary, ~35 HRC is attained after solution treating (annealing is not applied in VP80). The procedure should be slow heating (100 ºC/h) to 400 ºC and than heating (max. 300 ºC/h) to 880/920 ºC. After the temperature homogenised throughout, keep at this temperature for 30/60 min. Cooling can be performed in ar blast or oil, down to 100 ºC and then air cooling to room temperature. Ageing temperature: 490 – 590 ºC, hardness: 49 to 39 HRC. The material can be also used in the solution treated condition, ~35 HRC, without decreasing corrosion resistance or other properties. The material can be also used in the solution treated condition, ~35 HRC, without decreasing corrosion resistance or other properties.
