Product Description

Standard and Grade:
GB ***3 /4Cr*3/ ASIS **0ESR/ DIN 1.***3/

1. Size:
Round bar: Dia*****0mm
Flat: *****0mm*******0mm

2. Delivery Condition
Annealed: Less than **0HB
Pre-hardened: ******0HB (****6HRC)

3. Application
Suitable for making of the molds to be used under weak acid and wet environment
When using for mirror-grade plastic mold, it is recommended to use **6R material.

4. Characteristics
Superior resistance to carrions, no special care or maintenance needed for the mould
Smelted by using vacuum degassing, so that the steel quality 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 ***3R(Annealed less than **5HB), and ***3R( Pre-hardened ****6HRC)
***3R high level steel has better performance than the normal ***3 in view of mirror=grade workability an anti0rust. Other properties are the same as normal ***3, such as heat-treatment and shape change, welding performance, etc.
