What's the Different of Steel types？

The Four Types of Steel

Steel is a combination of two elements, iron and carbon. Steel are broken is broken into four types and then in those types steel is broken down into grades. There are four main types of steel, Carbon Steels, Alloy Steels, Stainless Steels, Tool Steels. Each different type of steels has unique characteristics which lead it to being used in it’s respected fields.

Carbon Steels

Carbon steels are the most common types of steel accounting for around 90% of steel production. Carbon steel typically contains up to 2% of carbon. Carbon steel is broken into three main sub categories, low carbon steel, also known as mild steel, medium carbon steel, and high carbon steel. The term carbon steel can also be used as a catch call term for steel that isn’t stainless steel.

Alloy Steels

Alloy Steels use different types of elements to influence the characteristics of the metal. Common elements are chromium, nickel, copper, molybdenum, vanadium, and aluminum. These elements are used to change the ductility, strength, machinability, and it’s corrosion resistance. Alloy steels can have up to 50% of it’s weight consit

Stainless Steels

Stainless steel is the go to steel for applications with corrosives. Stainless steel has to include chromium, usually around 11-12%. To be classified as stainless steel it has to have a minimum of 10.5% chromium content. Stainless steel is easily identified by it’s sheen and is commonly used in the food, medical, hard and architectural industries.

Tool Steels

Tool steels are commonly used in cutting and drilling equipment due to the higher heat resistance and hardness they get from the alloys they have in them. Tool steels commonly contain tungsten, molybdenum, cobalt and vanadium. There are 6 grades of tooling steel, air-hardening, water-hardening, D-type, hot-working, shock-resisting types, and oil hardening.

Construction steel price fluctuations Recently

Recently, rebar, wire, coil and other construction steel market continues to run, the price fell across the board, traders generally sell not smooth, most choose to price sales."China Metallurgical News" reporter said in an interview, the recent construction steel market business cold, traders generally to "price"  "warehouse"  "risk"  "three down" strategy to speed up the shipment.

Steel traders believe that from the current market supply, demand, inventory, cost and other factors, prices will continue to fluctuate.The uncertain factors affecting the market trend mainly include the following aspects:

First, there are changes in the middle end of the effective demand.Recently, countries in some regions have been affected by natural environmental disasters, regional epidemics and other factors, and blocked transportation.

Changes in the twenty building steel inventory.Recently, steel social inventory and steel mill inventory both increased.The increase in steel inventories has led to increased sales pressure on traders.

Third, the change of the regional market price difference.At present, the construction steel market price difference between the north and south regions is still relatively large, and the "north material south" process is accelerated.For example, on January 22, the premium price in Guangzhou, Guangdong, reached 4820 yuan / ton; the market price of the same product in Baotou, Inner Mongolia reached 4140 yuan / ton, and the price difference reached 680 yuan / ton; again, manufacturers in northern China tend to transfer resources to the south, which will increase the supply pressure on the southern construction steel market in the later period.

Fourth, the change of the ex-factory price of steel enterprises.Recently, the prices of raw fuels such as iron ore and coke continue to rise, and the production costs of steel enterprises continue to rise.Therefore, steel enterprises in the determination of the factory price is mostly to support with the increase price.
