Detailed Product Description: | Yong Wei mold steel, 4CR13 rod, Leizhou 4CR13 provided by Yong Wei steel mold. We are Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) located: Dongguan, Guangdong specializes in: mold steel, DC53, SKD11.SUS440C, SUS420 good surface corrosion workability and corrosion resistance: easy pattern formed plastic parts , and some plastics such as polyvinyl chloride in hydrochloric acid gas generated during the forming of the cavity corrosion. So for corrosive gases used in plastic 4CR13 die steel, corrosion-resistant steel to consider whether the good. To a reasonable choice of the chemical composition of the steel and the use of reasonable refining, thermal processing and heat treatment process to make the mold material wear resistance, strength and toughness to achieve the best fit. Strong wear resistance steel mold, in addition to steel mold steel also has the ability to thermal fatigue. Hot work die steel under service conditions in addition to cyclical changes in load, but also subjected to high temperatures and periodic thermal shock effect. Compared with the hardening atmosphere under vacuum oil quench hardening mold surface is relatively uniform, but slightly higher, mainly due to the vacuum heating, mold steel surface was an active state, not removal, does not produce an oxide film impede cooling. Heating under vacuum, the surface of the steel degassing effect, and thus has high mechanical properties, the higher the degree of vacuum in the furnace, the higher the bending strength. Vacuum quenching, the fracture toughness of the steel sheet improved 4CR13, generally improve tool life by 40% to 400% higher than the conventional process, or even higher. Cold mold vacuum hardening technology has been more widely used. Mold steel manufacturing is the basis for the entire industrial manufacturing technology and equipment, electronics, automotive, electrical, electronics, instrumentation, home appliances and telecommunications products, 80% to 90% of the parts have to rely mold forming, determines the shape of the mold of these products shape, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after the restructuring, will be increasingly high precision molds, mold steel requirements are also increasing. For a quenching medium cooling during the quenching operation. Mainly used in high, medium carbon steel parts, in order to ensure adequate hardened layer to prevent quenching crack. A process used to reduce the deformation. Commonly used in the water - oil, water - air, oil - air and other media. Slightly removed from the workpiece furnace stay a while quenching into water "cold be quenched" in the air also belongs dual media quenching. From this point of view, on the one hand, this winter seems to be earlier than in previous years, even with last year remain similar magnitude utilization rate dropped 4CR13 suppliers, raw material market pressures to be overlooked; on the other hand, as of early October, Key steel mills stock still as high as 15.689 million tons, compared with the normal inventory level was nearly three million tons, 2.189 million tons the same period last year Yijiao 4CR13, with winter near, corporate demand for return of funds to the inventory will increase, In this process may also take the initiative to cut production in order to reduce pressure on the stock of finished products. Taking into account the cuts during the APEC meeting in early November, Hebei and other places likely to face a decree, if the supply is gradually reduced expectations are confirmed, then the pressure on the raw materials market will be significantly higher. |
