1.Name of product: cold work tool steel 1.2550 /DIN 60WCrV8 / AISI S1   

 

2.Chemical Composition as following or customized :

 

Element	C	Si	Mn	Cr	S	P	W	V
content	0.55-0.65	0.7-1.0	0.15-0.45	0.90-1.20	≤0.030	≤0.030	1.7-2.2	0.1-0.2

 

3.DescriptionThis steel is one of the shock resisting tool steel types with very good thoughness in combination with high hardenability. Impact-resistant, tungsten-alloyed cold-work tool.

4.Applications

For cutting tools (dies, punchers) for plate, woodworking tools, blanking dies for cutting sheet metals up to 12 mm thickness, trimming and spliting dies, cold piercing punches, performing punches, shear blades, chipping knives, pneumatic chisels, coining tools, cold shear blades, ejectors.

 

5.Tool steel 1.2250 specification as following :

 

Round bar	Grade	1.2250	Flat bar	Grade	1.2250
	Max Dia	500mm		Min thickness	30mm
	Min Dia	45mm		Max thickness	500mm
				Min width	105mm
				Max width	1000mm

6.Soft AnnealingHeat to 710-750oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 225.7.Stress RelievingStress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.8.HardeningHarden from a temperature of 860-900oC followed by oil or hot bath (180-220oC) quenching. Hardness after quenching is 60 HRC.9.TemperingTempering temperature: See the data bellow
