Effect of Vacuum Heat Treatment on Microstructure and Properties of Superhard High Speed Steel M2Al

M2Al is a kind of cobalt-free super-hard high-speed steel. Vacuum heating promotes abnormal grain growth. Filling with inert gas for vacuum heating can increase the heating speed, hinder the formation of abnormally large grains, and improve the strength and toughness of M2Al steel. The most impo...

High-speed Steel Tools & Vacuum High-pressure Gas Quenching Furnace

The heating and cooling of high-speed steel tools in vacuum has the effects of non-oxidation, non-decarburization, small deformation, bright surface and degassing, which can significantly improve product performance and extend the service life of tools and molds. Therefore, it has received widesp...

Spring Heat Treatment Quality Inspection and Operation Precautions

Spring heat treatment quality inspection includes inspection before heat treatment and inspection after heat treatment. 1. Quality Inspection Before Heat Treatment: The rolled surface of steel is often the surface after the spring is made, so there should be no cracks, folds, scars, hair lines, b...

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 i...

The Main Factors Affecting the Degree of Graphitization of Cast Iron

Because the crystal structure of iron is very different from that of graphite, and the crystal structure of iron and cementite is closer, ordinary cast iron can only get white cast iron under normal casting conditions, but gray cast iron is not easy to obtain. Therefore, it is necessary to promot...

Advantages, Temperature and Time of Carbonitriding of Metallic Materials

1. Compared with gas carburizing, carbonitriding has the following advantages: 1) The same infiltration layer depth can be obtained at a lower temperature and in the same time; or at the same processing temperature, the co-infiltration rate is faster. 2) Carbonitriding does not precipitate carbon...

The Difference Between Austempering and Graded Quenching

Austempering: After heating the steel to make it austenitized and homogenized, it is quickly cooled to a certain temperature in a given bainite transformation temperature zone, and maintained at that temperature for a certain period of time to make it undergo isothermal transformation to form she...

Application of Metal Powder Injection Molding

Due to the use of injection molding, the metal forming process can produce very complex parts with various alloy materials. Its complexity far exceeds any metal forming process including other powder metallurgy processes, including: various external grooving, External thread, tapered outer surfac...

Common Steel Materials and Heat Treatment Process For Machine Tool Gears

Machine tool gears can be divided into low-speed and low-load gears, medium-high-speed and medium-load gears, high-speed impact load gears, and large-section gears. The heat treatment processes of gears for different purposes are different. The heat treatment processes of various gears will be in...

Introduction to Heat Treatment of Martensitic Stainless Steel

Commonly used martensitic stainless steel has a carbon mass fraction of 0.1% to 0.45%, and a chromium content of 12% to 14% (mass fraction). It belongs to chromium stainless steel, usually referred to as Cr13 stainless steel. Typical steel grades are 1Cr13, 2Cr13, 3Cr13, 4Cr13, etc. This type of ...
