Steel name: W320
Diagram No.: 2275
Mat.No. (Wr.Nr.) designation: ~1.2365
DIN designation: 32CrMoV12-28
AISI/SAE designation: ~H10
JIS designation: SKD7
Chemical composition in weight %: 0.31% C, 0.30% Si, 0.35% Mn, 2.90% Cr, 2.80% Mo, 0.50% V
Steel group: Hot work tool steels
Properties: Hot work tool steel featuring a fine combination of heat checking resistance, hot strength and impact strength; ad mits water cooling.
Applications: Highly stressed hot work tools, mainly for the processing of heavy alloys, such as mandrels, dies and containers for metal tube and rod extrusion; hot extrusion tools; tools for the manufacture of hollows, screws, rivets, nuts and bolts. Die casting tools, forming dies, die inserts, hot shear blades.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1010 to 1050°C (1850 to 1922°F) Oil, salt bath (500-550°C / 932-1022°F), Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 52 - 56 HRC
Tempering: Slowheating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece thickness but at least 2 hours / cooling in air. It is recommended to temper at least twice. A third tempering cycle for the purpose of stress relieving may be advantageous 1st tem pering ap prox. 30°C (86°F) above maximum secondary hardness. 2nd tempering to desired working hardness. The tempering chart shows average tempered hardness values. 3rd for stress relieving at a temperature 30 - 50°C (86 to 122°F) below highest tempering temperature.
