The points you must know about steel
Working in the steel industry, we need to understand of steel. Here are some points we must know.
What is steel
Steel is indispensable in the infrastructure construction and the overall economic development of every country, and it is used widely in industry, construction, petrochemical engineering, etc.
Statistical data show that construction, machinery, automobiles, shipbuilding, railways, oil, household electrical appliances, containers, etc. are the eight industries with the largest proportion of steel consumption. Their steel consumption amount is above 80%. And construction is the largest steel consumption industry, followed by machinery. The annual steel consumption in these two industries accounts for about 70%.

What is steel made of
Steel is materials with certain features made by pressing steel ingots and steel billets into particular shapes and sizes. Most steel materials are processed by pressure to make it (billets, ingots, etc.) get plastically deformed. Depending on the processing temperature, there are cold processing steel and hot processing steel.

What Is Stainless Steel
If the steel material has a non-rust property is called stainless steel, which is resistant to weak corrosive media such as air, steam, water, etc.
Steel that is resistant to weak corrosive media is always called stainless steel. And steel that is resistant to chemical media is referred to as acid-proof steel.
Because of the difference in chemical composition between them, stainless steel maybe is not resistant to chemical media corrosion, while acid-proof steel generally has great rustless property. The corrosion resistance of stainless steel depends on the alloying elements contained in it.
Properties of Steel
The structural properties of steel directly affect the performance of steel and what kind of products can be made. Its performance also includes many factors, such as toughness, plasticity, strength and etc. Some properties of different types of steel are different, but most of them are similar.
The classification of steel is more detailed and more diverse in the market right now. The performance of different steels is different, but as long as some performance is strengthened or weakened to meet the industry requirements.

The Types of Steel
Steel are abundant in variety. In order to manage and produce, it must be classified. And it can be divided into cold work mold steel, hot work mold steel, plastic mold steel, high speed steel, alloy steel, carbon steel, free cutting steel and etc.
And according to the use of steel, it can be divided into:
- Steel for Construction and Engineering: ordinary carbon structural steel, low alloy structural steel.
- Tool Steel: carbon tool steel, alloy tool steel, high speed tool steel

When you need to purchase steel based on the needs of your company, I think you should figure out these things as below:
- Steel grade and specification
- tensile strength
- Impact toughness, cold brittleness
- The way of heat treatment
- Surface state
When you have the choices of steel supplier, you need to choose the quality and price meet for your company. I think you really know: you will get what you pay for. If the steel price lower than standard, it must be bad. And the important point is that the steel supplier if has stock right now. And you need to know the steel supplier for some points as below:
- steel can be supplied from stock?
- How much is the price? If the quantity is large, how much is the discount?
- Steel quality inspection
- What kind of payment method is accepted and how long is the delivery time?
- You can even request steel samples to get a better understanding of the supplier.
Steel is an important commodity related to the national economy and people's livelihood, and its price fluctuations are affected by many factors.
The development of the steel industry is also positively related to the development of the country's economy. The speed of economic growth directly affects consumption demand for steel, which also affects the price of steel.
At present, most of the steel is produced from iron ore. So the changes of iron ore prices are a key factor to affect the production costs of steel.
Supply and Demand Situation
The price of products has a close relationship with the supply and demand situation.
The technical level is one of the important factors affecting the price of steel. The influence as below:
- The impacts on the way of the production process, and then influence the production cost.
- Technological advancement leads to the production of steel substitutes, then reducing the demand for steel.
- Technological advances will create more properties of steel to meet more requirements of industry products, thereby increasing the demand for steel.
