　　part name steel grade outline size (mm) characteristic technical requirements quenching results

concave die T460 x 100x 25 has large porous volume, narrow length and small hole spacing tolerance HRC60~62, hole spacing tolerance soil 0.1mm fully meets the technical requirements

　　piston rod 45 Φ6x 385?& Phi; The 48x 385 rod is slender, with different cross-section thicknesses, and is easy to bend HRC45 after quenching 50 hardness & gt; The distortion of HRC45 is about 0.5mm

　　cold extrusion concave die 40Cr Φ HRC46 ~ 48 HRC47 ~ 48, which is easy to crack on the upper corners of the 90x 45 cavity after quenching, fully meets the technical requirements
