What is low alloy structural steel

Low alloy structural steel refers to the alloy structural steel with total alloy composition less than 5%. The carbon content of this kind of steel is similar to that of low carbon steel, and it is mainly strengthened by a small amount of alloy elements to improve toughness and weldability. Its strength is much higher than that of the same carbon steel. Widely used in pressure vessels, chemical equipment, boilers, bridges, vehicles, ships and large steel structures. Alloy elements such as manganese, silicon and molybdenum cause solution strengthening. Vanadium and niobium can refine grains and improve toughness. Molybdenum can improve … Lee mas

General Comparison between Cast Iron and Steel

Cast iron and steel may look very similar on the surface, and they have different advantages and disadvantages from production to application. Understanding these advantages and disadvantages, and choosing the right ones may mean unforgivable differences between strength and durability and cracked or deformed parts, which can quickly lose luster. Table of Contents Carbon content MachinabilityCharacteristic Castabilitycompressive strengthImpact resistanceCorrosion resistanceMachinabilitycostSpecies of cast iron and steel Carbon content Both iron and steel are ferrous metals mainly composed of iron atoms. In manufacturing, however, it’s not that simple. There are many different alloys and grades. In fact, carbon composition is the main … Lee mas

Application of Grain Growth Inhibitors in Cemented Carbide

When WC grains in cemented carbide are less than 0.5 μ m, the finer the grains are, the fewer the defects are, and the higher the bending strength and hardness are The particle size of WC powder used to produce ultrafine cemented carbide is much smaller than that of WC powder used in general cemented carbide. The WC powder has high activity and is easy to cause grain growth in the sintering process, which is one of the crack sources. At present, there are two main methods to control the grain size: First, a new sintering process is adopted. The … Lee mas

Something Informative about Metallurgy

Powder metallurgy is the technology of making metal powder or using metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming, sintering, and manufacturing metal materials and various types of products. There are some similarities between powder metallurgy and ceramic production, which belong to powder sintering technology. Therefore, The metallurgy technology can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials.

Do You Know the Cause of Failure of Mining Pick and the Way to Improve Its Performance?

Mining pick is one of the vulnerable parts in coal mining and roadway driving machinery, and it is the main tool for coal falling and coal breaking. Its performance directly affects the production capacity of coal mining machinery, power consumption, working stability and the service life of other related parts. With the increase of people’s demand for energy, especially for coal, in order to improve the mining efficiency, the power of the shearer is increasing, and the quality of the pick is required to be higher and higher. As the material of the shearer pick, it is required to have … Lee mas

The Straightforward and Informative Intro about Common Elements Added into Alloy Steel

As is familiar to us, elements to be put into some kind of steel alloy for improving or altering its properties are regarded as alloy elements. Commonly used alloying elements are chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, silicon, manganese, aluminium, copper, boron, rare earth, etc. Phosphorus, sulphur and nitrogen also play the role of alloys in some cases. Table of Contents CrNickel (Ni)MoWolfram(W)Vanadium(V) Cr Chromium can increase hardenability and secondary hardening of steel.
