Heat Treatment Characteristics of Age-hardened Steel Plastic Mold
1. The heat treatment process of age hardening steel is divided into two basic steps. First, the solution treatment is carried out, that is, the steel is heated to a high temperature to dissolve various alloying elements into the austenite, and after the austenite is completed, the martensite str...
Heat Treatment of Steel for Carburizing Plastic Mould
Steel for carburizing plastic molds is mainly used for cold extrusion molding plastic molds. In order to facilitate cold extrusion molding, this type of steel must have high plasticity and low deformation resistance in the annealed state. Therefore, low or ultra-low carbon content is required for...
Heat Treatment of 3Cr2Mo (P20) Plastic Mold Steel
3Cr2Mo steel is a commonly used grade of imported plastic mold steel from the United States, and it is also the only plastic mold steel formally accepted in the GB/T 1299-2000 Alloy Tool Steel. 1. Chemical Composition and Critical Phase Transition Point The chemical composition is shown in Table ...
Heat Treatment of 3Cr2NiMo(P4410) Plastic Mould Steel
1. Chemical Composition and Critical Phase Transition Point. 3Cr2NiMo steel is an improved type of 3Cr2Mo steel. It is 0.8%~1.2% nickel added to 3Cr2Mo steel. Its chemical composition is shown in Table 1. The actual composition of the domestic trial-produced P4410 steel is consistent with the imp...
Heat Treatment of 25CrNi3MoAl Steel
25CrNi3MoAl steel is a low-nickel and cobalt-free age-hardening steel. This is a new type of age-hardening steel developed by referring to the composition of similar foreign steels and improving the characteristics of my country’s smelting industry and the performance requirements of the us...
Heat Treatment Process of Automobile Half Shaft
The semi-axle is an important structural part for the rear axle of the automobile to receive torque and a certain impact force. It is one of the main components for transmitting power. During the working process, the torque from the main reducer and differential is finally transmitted to the driv...
Test Method For Leakage Of Vacuum Furnace
The inside of the vacuum furnace atmosphere will directly affect the product’s surface treatment effect, the atmosphere in the furnace is determined by the tightness of vacuum furnace, so to ensure the quality of workpiece, the first thing to keep the vacuum furnace gas tightness is good, t...
The Insulation Layer Of Vacuum Heat Treatment Furnace Is Mainly Used For Cylindrical Reasons
Vacuum Heat Treatment Furnace Insulation Layer of the Main Uses First, the heat insulation layer of vacuum heat treatment furnace is one of the important parts of the heating chamber. Under normal circumstances, the heat insulation layer is made of cylindrical as far as possible, because, from th...
Heat Treatment Process of Cr12MoV Steel Cold Extrusion Die
Cr12MoV steel is one of the most commonly used mold steels in my country. Because of its high hardness, high strength, and small volume deformation during heat treatment, it is mostly used for high-load, high-precision, and long-life cold-deformed molds. At present, there are many factors that ca...
The Role of Heat Treatment In the Reducer
Heat treatment is a very important link in the manufacture of reducer, but many users do not understand the role of this heat treatment, so in order to facilitate everyone’s understanding, the following is an introduction to its role. 1. Surface Quenching Common surface quenching methods in...
