Structural parts, namely complex mold sliders, lifters, straight top mass. Structure design is very critical, related to the life of the mold, the processing cycle, costs, product quality, etc., so the design of complex integrated capability of the core structure of the mold designers are higher, as the pursuit of simpler, more durable, more economical design. Compressive yield strength and compression bending strength: the strength of the mold is often subjected to high pressure and bending in use, thus requiring the mold material should have a certain compressive strength and flexural strength. In many cases S500 mold price, performed compression testing and flexural testing conditions closer to the actual working conditions of the mold (eg, compression mold steel when measured yield strength and punch work demonstrated by the deformation resistance more consistent). Nitriding process currently used ion nitriding, high frequency nitriding and other technology. Ion nitriding nitriding time can be shortened, and the availability of high quality nitrided layer. Ion nitriding can improve the casting mold corrosion resistance, abrasion resistance, thermal fatigue resistance and adhesion. Carbonitriding be carried out in a gas or liquid medium, medium, small diffusion layer brittle, permeation time is much shorter than the nitriding time. Die casting, hot extrusion die through after carbonitriding can significantly improve the thermal fatigue performance. Carbonitriding for cold heading die, cold extrusion die, Die, drawing die and so have a very good application effect. S136H is pre hard, but the hardness is not very high, at around HRC30 degrees, do not require heat treatment, S136 steel is hardened material, very soft, need to use the S500 quality after quenching, after quenching hardness can reach HRC58 degrees . The former requirement ratio for small quantities of injection mold, which is used in large quantities. So usually happen in large quantities S500 wholesalers, can be ordered S136 steel, different on these two areas, there is a demand of the customer can be the difference between these two areas, which were combined amount of the purchase, both to save costs, but also conducive to reasonable buy better quality steel! Metal heat treatment requirements for material handling must also have a clear enough understanding. Know the composition of features, performance characteristics, scope critical point, the physical and chemical parameters or characteristics of the material of various materials (here including thermal properties, swelling properties and phase transition has occurred and other information). Domestic part have an influence in the local medium-sized steel mills have begun overhaul before and after National Day, which also makes the availability of resources in some areas to reduce the appearance of tight supply of steel products, while taking into account the ongoing maintenance of large-scale steel mills have not yet formed the size of the domestic steel supply and demand pattern overall temporarily unable to change, but in steel prices continued to fall and the upcoming winter situation S500, the total domestic steel production is the line into a slow decline. Also, another concern news is that a substantial increase in China's steel exports this year, the domestic supply and demand pressures eased to some extent, but the Government has recently said that next year China's steel export tax rebate policy will be canceled when the steel export growth is expected to occur changes in steel prices will increase the uncertainty of the market outlook.
