1.2312 HOT ROLLED MOULD STEEL PLATE           

 

1. Chemical Composition (%):

Grade	C	Si	Mn	P	S	Cr	Mo
1.2312	0.35-0.45	0.30-0.50	1.40-1.60	≤0.035	0.05-0.10	1.80-2.00	0.15-0.25

 

2. Dimensions:

Plate: T20~300*W1600~2300*L3000~5800mm

Block:T200~800*W400~1200*L1500~3000mm

Round bar: Dia 100~500*L2000~4000mm

 

3. Properties:

Plastic mould steel with excellent machinability properties because of the high S content, good toughness properties, good wear resistance, uniform hardness in all dimensions, dimensional stability, requiring no heat treatment, 280 - 325HB hardened and tempered condition, suitable for nitriding to increase wear resistance, not suitable for chrome plating, polishing and etch graining.

 

4. Applications:

Injection dies without special surface requirements and low mechanical stresses, medium and large sized moulds for plastic processing, dies of light alloys with low melting point, mould fittings, mould frames for the injection molding and die casting industries, components for general mechanical engineering, tools for synthetic plastics processing, die holders, support plates, casings, chases, recipient sleeves, constructional parts, hyrdo forming tools.

 

5.Inspection:

SEP1921/84 GR.3, CALSS C/C
