The relative standard steel

AISI	GS	ASSAB	JIS
H13ESR	GS344ESR	8407	SKD61

Basic characteristics of

1.ESR steel, high purity, good anti-soluble.

2.Uniform organizational structure, thermal strength, toughness with good, high-temperature molten metal erosion.

3.Superior performance of high-temperature tempering, 600 ℃ the following work is not easy to decrease the hardness, dimensional accuracy, durability and stability.

4.Resistance to thermal fatigue, anti-cracking ability.

Practical Points

1.Higher longevity requirements of the whole polishing and hard plastic mold (HRC52-54)
Such as: Bakelite plastic mold.

2.Tin, lead, zinc and aluminum die-casting mold (such as the engine radiator, lighting, decorations) aluminum extrusion die (such as aluminum door frames, computer radiator), forging dies (such as connecting rod, crank, high grade stainless steel knife, etc.)

3.Low production of copper alloy extrusion, die-casting mold.
