DIN 1.2311 Prehardened Mold Steel Plate For Large-sized Precision Plastic Mould

Standard: GB/T 1299-19853.

Similar grade: AISI-P20, DIN-1.2311, JIS-PDS-3, GB-3Cr2Mo

Introdution:

Grade P20 / 1.2311 is an internationally widely used plastic mold steel, its good mechanical properties, high hardenability can make Larger cross-section steel to obtain more uniform hardness, and this steel has good polishing performance and high mold surface finish.

Chemical Composition(%):

Available size(%):

Features:

♦ 1, Pure steel vacuum degassing refining process for polishing or etch processing plastic mold.

♦ 2, Pre-hardened state of supply, without heat treatment can be used directly in the mold, shorten the construction period.

♦ 3, By forging rolling processing, compact structure, 100% ultrasonic testing, non-porous, needle defects.

♦ 4, For the production of plastic mold and die casting low melting point metal mold material.

♦ 5, This steel has good machinability and mirror polishing properties.

♦ 6, Hardness: 285-330HB(30-36HRC).

♦ 7, Good dimensional stability.

♦ 8, With long service life,Mold die life up to 50W times.

Heat treatment:

Applications:

♦ 1, Plastic molds for injection compressing and injection molding.
♦ 2, TV cabinets,drum mold of washing machine,etc.
♦ 3, Often used in the manufacture of television cabinet, washing machine, refrigerator inner shell, buckets, etc.
♦ 4, Main components of overloading mold.

Devlivery condition:

Hot rolled or forged, black surface, pre-hardened or tempering to 28-33HRC/30-35HRC.

When using this steel mold, usually make quenching and tempering treatment first that the hardness is HRC28 ~ 35 (pre-hardened), and then by cold working manufactured molds can be used directly.

In this way, it can guarantee the using performance of the mould, and avoid deformation of the mold causes by heat treatment.

Therefore, the steel is suitable to manufacture big or medium-sized precision plastic mold and low melting point, tin, zinc, lead alloy die-casting molds.
