2023-7-11What are the advantages of alloy steel compared with similar carbon steel?
In addition to the iron and carbon of ordinary carbon steel, alloy steel is also added with other alloying elements according to performance requirements, such as common chromium, nickel, molybdenum, -
2023-7-10What is the heat treatment process of alloy steel?
The heat treatment process of alloy steel is divided into low-carbon alloy steel, medium-carbon alloy steel, and high-carbon alloy steel. Low-carbon alloy steel generally needs to be carburized, quenc -
2023-7-09The difference between alloy steel and alloy tool steel
1. The difference in meaning: Alloy steel is called alloy steel by adding other alloying elements besides iron and carbon. An iron-carbon alloy formed by adding an appropriate amount of one or more al -
2023-7-08The difference between low carbon steel and alloy steel
The difference between low carbon steel and alloy steel are: 1. The concept is different: low carbon steel is carbon steel with a carbon content of less than 0.25%. Alloy steel is steel in addition to -
2023-7-07What are the precautions for purchasing alloy steel?
1. Material quality: The quality and performance of alloy steel are closely related to the quality of the material, so it is necessary to select high-quality alloy steel materials to ensure the qualit -
2023-7-06What is the main material of alloy steel?
Alloy steel is a steel composed of iron, carbon and other alloying elements. Compared with ordinary carbon steel, alloy steel contains a higher proportion of alloying elements, such as chromium, molyb -
2023-7-05What are the classifications of alloy steel?
Alloy steels can be divided into three groups according to the propensity of the various elements to form carbides in the steel: ① Strong carbide forming elements, such as vanadium, titanium, niobium, -
2023-7-04What are the classification characteristics of austenitic heat-resistant steel?
Austenitic heat-resistant steel matrix is heat-resistant steel with austenitic structure. This type of steel contains more austenite-forming elements such as nickel, manganese, and nitrogen. It has go -
2023-7-03Heat-resistant steel has good heat resistance and oxidation resistance
Alloy steel with high strength and good chemical stability at high temperature. It includes two types of anti-oxidation steel (or high-temperature non-skinning steel) and heat-strength steel. Oxidatio -
2023-7-02Common welding methods and different applications of heat-resistant steel
Commonly used welding methods: submerged arc automatic welding (SAW), electrode arc welding (SMAW), inert gas shielded welding (GTAW or TIG), flux cored arc welding (FCAW), etc. Among them, SAW is mai -
