Description

3Cr17NiMo-ESR plastic die steel
Technical field
The present invention relates to plastic die steel technical field, especially a kind of 3Cr17NiMo-ESR plastic die steel.
Background technique
Plastic die steel is started late in China, and as the market demand sharply expands, Domestic Mould Steel research starts upsurge, The mould steel series of China's independent research just gradually expands, and the plastic die steel for being included in professional standard at present is more than 20 kinds existing, China's plastic die steel system is preliminarily formed, such as currently used 3Cr17NiMo plastic die steel is with reference to Sweden S- 136 and German 1.2316 grades of steel on the basis of the novel plastic mould steel that designs.Although its overall performance is also more outstanding, Still there is certain gap compared with gate-in mold system steel, design requirement is not achieved in the mold of manufacture on service life, therefore, to steel Material processing technology is adjusted, and further enhances 3Cr17The performance of NiMo plastic die steel is the emphasis researched and developed at present.
Summary of the invention
The purpose of the present invention is to the 3Cr of the current country17NiMo plastic die steel overall performance and use demand phase Than still having certain gap, design requirement is not achieved in the mold of manufacture on service life, provides a kind of quenching and tempering type 3Cr17NiMo-ESR plastic die steel.
A kind of 3Cr of the invention17NiMo-ESR plastic die steel, it contains the ingredient of following weight percentage: C:0.30- 0.40%, Si≤1.00%, Mn≤1.00%, Cr:16.00-17.50%, Ni:0.650-1.00%, Mo:0.80-1.25%, S≤ 0.020%, P≤0.020%, surplus Fe, the plastic die steel have the hardness of HRC30-36；The plastic die steel exists The quenching treatment temperature of steel billet is 1020-1050 DEG C, soaking time 10-30min in process, and oil is cold or quenches liquid cooling； Softening annealing temperature is 780-820 DEG C, is furnace-cooled to HB≤230；Tempering temperature is 580-620 DEG C；The steel billet forges compasses lattice φ 60-400mm, flat bar gauge thickness are 20-400mm, width 60-800mm.
Preferably, the plastic die steel contains the ingredient of following weight percentage: C:0.35%, Si:0.8%, Mn: 0.6%, Cr:16.8%, Ni:0.8%, Mo:1.0%, S:0.015%, P:0.015%, surplus Fe.
Product of the present invention has the advantage that with respect to existing product
1. making steel that there is better acid-proof performance, and use electroslag remelting technique, steel by being adjusted to processing technology Matter is purer, mirror finish more excellent performance, easy soldering；
It is suitable for direct die sinking processing and fabricating 2. steel pass through Pre-hardening treatment, also can provide soft state steel according to customer demand Material and special stiffened heat treatment process；
It is suitable for the advanced hollow article of adornment of manufacture 3. having excellent corrosion resistance and polishing performance, cosmetics containers, food hold The plastic moulds such as device；
It is suitable for large-scale, super-huge high mirror surface mould manufacture 4. the forging circle of preparation, flat bar billet specification are big, quality can be better than state Outer import similar product.
3Cr of the invention17NiMo-ESR plastic die steel, hardness reach HRC30-36, corrosion resistance, polishing performance Better than Germany 1.2316, acid-proof effect is good, mirror finish function admirable, is suitble to direct die sinking processing and fabricating, particularly suitable production The plastic mould of excellent corrosion resistance and polishing performance, is largely used to advanced hollow article of adornment, cosmetics containers, food The processing mold of container etc., wide market have high economic benefit.
