2738 Mod TS THRUHARD SUPREME
Recently developed plastic mould steel, distinguished from grades 2311 and 2738 by: • Higher hardness and better through-hardenability. • Polishability up to 600 grit (high gloss finish reliability on request). • Grain reliability even with sensitive etch-graining designs. Improved weldability • Higher thermal conductivity we recommend grade 2738 mod.TS(HH). Nitridable, hard chrome plateable, flame hardenable as delivered; its higher basic hardness provides better support for surface finishing (such as PVD coating). HighHard: 2738mod.TS(HH). Quenched and tempered to 310–355 HB ( ͇˄ approx. 1050 – 1100 MPa)*. Normal hardness: 2738mod.TS. Quenched and tempered to 280–325 HB ( ͇˄ approx. 950– 1100 MPa)*
Compression and injection moulds to accommodate large dimensions such as bumpers, dashboards, chairs, rubbish bins, bottle crates, television cabinets, etc.
