The Nitriding process of steel

Nitriding is a chemical heat treatment process in which nitrogen atoms penetrate into the surface of the workpiece at a certain temperature and medium. Common methods are liquid nitriding, gas nitriding, ion nitriding, the latter two types are the most commonly used. The traditional gas nitriding is to put the workpiece in a sealed container…

Carburizing Steel VS Nitriding Steel

In the last article, we introduced carbon carburizing in detail. In general, the carburizing is to heat the steel above to the critical temperature and then make the carbon infiltration and diffusion, so it is also called Austenitic chemical heat treatment. It is a kind of high-temperature chemical heat treatment, and the deformation of the…

What is Carburizing Steel?

Carburizing is a surface heat treatment method of quenching and low-temperature tempering after expanding carburizing atoms to the surface of steel parts. Carburizing process can significantly improve the wear resistance, durability, toughness and other properties of steel. After treatment, the core of the parts is low carbon martensite with sufficient strength and toughness, and the…

What’s Plastic Mirror Die Steel?

Mirror plastic die steel is a kind of precipitated hardening aging steel that is developed to adapt to transparent plastic and rubber products with high surface quality and high corrosion. It for bainite and martensite after heat treatment of duplex mixed matrix organization, having good cold and hot machining performance, comprehensive mechanical properties and mirror…

What’s HSLA steel?

As we all know, the strength of steel increases with the increase of carbon and manganese content, and the addition of Ti or Nb microalloying elements can obtain higher yield strength at low carbon equivalent. The high strength low alloy steels, HSLA for short, are engineering structural steels with a small amount of Mn, Si…
