1 Standard and Grade:
GB 2083 /4Cr13/ ASIS 420ESR/ DIN 1.2083/

2. Size:
Round bar: Dia20-250mm
Flat: 13-120mm*151-610mm
Plate: 20-150mm*1000-5800mm

3. Delivery Condition
Annealed: Less than 230HB
Prehardened: 280-330HB(30-36HRC)

4. Application
Suitable for making of the molds to be used under weak acid and wet environment

5. Characteristics
Superior resistance to carrions, no special care or maintenance needed for the mould
Smelted by using vacuum degassing, so that the steel quallity is more purified, the structure is even and dense and the polish property is excellent.
Already pre-hardened and no need for future heat treatment, suitable for direct mold cutting.

We also provide Electro Slag Remelting (ESR) high level material, named 2083R(Annealed less than 235HB), and 2083R( Prehardened 30-36HRC)
2083R high level steel has better performance than the normal 2083 in view of mirror=grade workability an anti0rust. Other properties are the same as normal 2083, such as heat-treatment and shape change, welding performance, etc.
