Product Introduction
2738 is a hardened and tempered, not corrosion resistant plastic mould steel. Because of the Ni-addition,
there is no hardness decrease in the center of large sizes (up to 600 mm). A special melting technology offers good machinability.

2738 is in the class of Plastic mold that was develoed from 2311 by adding Nickel 1.0 Selling condition is quench and tempered 
So, free from size changing after hardening Hardness range is 280-325 HB (29-34 HRC) 
Suitable for big size plastic mold which thickness over 400 mm High strength with hardening ability .
Made of steel that pass degassing process in vacuum result in polishing ability .Can do texturing or EDM .
Also, can do surface hardening by various procedure.
