China alloy steel special steel round bar

1.2714 Forged Hot Work Mould Steel Round BarAlloy tool steel with lower content of alloy elements. It is also the traditional hammer forging die steel. It has good toughness, strength and wear resistance, hardenability, and 300 * 300 * 400mm workpiece can be fully quenched. The utility model is suitable for producing large and medium-sized hammer forging dies (>400mm) with complicated shape and heavy impact load.Chemical Composition(%)GradeCSiMnCrMoPSNiV5CrNiMo0.50-0.60≤0.40.50-0.800.50-0.800.10-0.30≤0.030≤0.0301.40-1.80-L60.65-0.750.10-0.500.25-0.800.60-1.20≤0.5≤0.030≤0.0301.20-2.00-1.27140.50-0.600.10-0.400.60-0.900.80-1.200.35-0.55≤0.030≤0.0301.50-1.800.55-0.15SKT40.50-0.600.10-0.400.60-0.900.80-1.200.35-0.55≤0.030≤0.0201.50-1.800.55
1, Features:
1) Heat resistant wear-resistant forged steel, excellent impact resistance, with proper hardness and good toughness.
2) The composite has good mechanical properties and high hardenability, and can make the steel with larger section size obtain a more uniform hardness.
3) Good optical rotation performance is made on the surface of the mold with low roughness value of 90.
4) Quenching and tempering treatment, hardness of 52 ~ 62HRC (pre hardening),
5) Can be used directly after cold processing into mold, ensure the use of the mold performance, but also to avoid the heat treatment caused by the deformation of the mold.2, Application:
1) The steel is used to make Valve all kinds of big and medium hot forging dies
2) Suitable for all kinTelecommunication & Broadcasting ds of medium and large hammer forging dies with complex shape and heavy impact load
