Polishing 1.2311 P20 Plastic Mould Steel 3Cr2Mo ASSAB-618 700mm

1.2311 MOLD STEEL

Standard: equivalent to China 3Cr2Mo, Sweden (ASSAB) 618, United States P20, Japan (Hitachi) HPM2

1.2311 mold steel has good comprehensive mechanical properties, high hardenability, and good polishing performance. It can achieve relatively uniform hardness for large-section steel (with a maximum pre hardening thickness of 700mm), which not only ensures the performance of the mold, but also reduces the production cycle and cost of the mold.

Main application: mainly used for molds with high surface finish requirements (such as home appliance shells and automotive interiors)
Ornaments, etc.), this steel grade is suitable for making large and medium-sized plastic molds.

Chemical composition

Physical properties: the physical properties of 1.2311 steel are shown in the table below, with its density of 7.81Kg/m3, elastic modulus (room temperature) E: 21200MPa, trimming modulus (room temperature) G: 825x103 MPa, and Poisson's ratio's ratio u: 0.288.

Supply hardness: pre hardened (quenched and tempered): HRC28-35

Heat treatment

Heat treatment after forging (normalizing+tempering)

Six main products series (4.3 million tons)
1. Welding Materials
2. Shipbuilding section
3. High-strength pre-stressed concrete steel bar
4. Forging ingot series
5. Steel ball series for bearing & mining industry
6. Flange & End Plate

As our develop strategy, we have been focusing on the complete production process mode which we deem will bring us synergy, so recently, another new product, i.e. welding consumables will be added to our catalog which will cover all series such as gas-shielded solid welding wire、flux cored wire、submerged arc wire、argon arc wire etc.

We have two main advantages for LT welding wires:
Fully integrated production process, i.e., with the support of upstream world class steel making facilities in house from same group company.
Newly developed production process with latest technology and know-how, i.e., fully automatic production which will be the assurance of quality control.
