2017 iron and steel industry is still in transition stage, the steel price is difficult to rise

China steel industry association recently reported, in 2017, China's steel demand is expected to remain stable, but the Shinestar of iron and steel institute considered think, due to the increasingly complex market environment at home and abroad, the steel industry is in a stage of transition to erase, not big changes in the overall market, steel prices to rise sharply. 

As Angle steel, galvanized Angle steel, channel steel, galvanized channel steel, metal steel board, open the tablet, and other products production services, Shinestar group have been very concerned about China's steel prices. In 2016, steel prices rose sharply, the iron and steel industry so reverse the depth of loss, profit. The first 11 months of the industry total profit of 33.15 billion yuan, and compared with the loss of 52.9 billion yuan.

Back in 2016, the Shinestar of iron and steel institute considered think, push factors of rising steel prices, the first is to continuous supply power limiting capacity policy; Second, real estate, automotive industry needs the strong recovery from improved more than expected; Three is a loose money provide ample liquidity to markets; Four is the coal 276 working days policy and the high grade iron ore resources nervous cause to rising raw material prices increase the cost driver. In 2017, the production capacity to the above factors, in addition to policy continues to strengthen, the other three factors will be significantly weaker. And iron and steel production capacity to strength will be bigger, at the same time, with the real estate enter the downward cycle, real estate development, automobile electrical appliances commodities, such as consumer goods growth is expected to also will fall. Based on this, in 2017 the domestic hong kong-listed is expected to double weak in supply and demand situation, the push of iron and steel production capacity to supply side and demand side real estate regulation and control of overweight, or will become the main affect domestic steel prices to logic.

Shinestar of iron and steel research institute said,in the face of the market in 2017, are full of confidence, also want to clearly recognize that although the steel industry has realized the profit, but it is only out of the trough, is not completely out of the woods, the industry is still in the small profit operation, still faces many difficulties and problems, not blindly.

In front of the 2017 has arrived, Shinestar group will keep optimistic attitude, we will continue to do yourself, constantly to develop more high quality of Angle steel, galvanized Angle steel, channel steel, galvanized channel steel, metal steel board, open the tablet, and Carbon steel pipe manufacturer, further to meet customer demand.

Low,Medium and High Carbon Steel

The world of carbon steels can be challenging to wrap your head around. There are many different options to choose from, and each type of steel has different benefits. The main differentiating factor is the amount of carbon that is mixed with iron during production. Other materials, mainly metals, can be added to change the physical properties. Notably, chromium is added to form stainless steel, while other  big picture, there are three distinctions between carbon steels: low, medium, and high.

Low carbon steel

Low carbon steels such as 302, 304 or 316 grades of stainless are typically used in applications which require high degrees of corrosion resistance but do not require a hardened surface. The carbon content of these steels typically range between 0.03-0.08%, and consumers typically use these grades of stainless (often without thinking about it) in kitchen equipment, silverware or almost any grade of un-plated steel used in food preparation. It’s great because it can survive the dishwasher without rusting, but it cannot be case hardened due to the very low carbon content.

While it can be used to make linear shafting, it isn’t suitable for loaded ball contact. So if a linear ball bushing were to be used on a soft 304 stainless steel shaft, for example, the balls in the bearing would quickly impact the shaft surface, resulting in visible ball tracking on its surface and a drastic reduction in both bearing and shaft life. It can, however, be used in conjunction with polymer, plain-style bearings which provide great options for both corrosion resistance and self-lubrication. For the right applications, a 300 series stainless steel linear shaft presents a great option for withstanding tough environmental conditions! 

Medium carbon steel

Medium carbon steels include grades with carbon contents ranging from 0.25% to 0.60% of the steel mass. Medium carbon grades are typically employed in conjunction with alloys such as chromium, nickel and molybdenum to produce high strength, wear resistance and toughness. Products using medium grades of carbon steel include gears, axles, studs and other machine components that require optimal combinations of strength and toughness.

Medium carbon steels have good machining characteristics, and one of the more popular grades used in machined steel product is AISI 1045.   AISI 1045 can also be hardened by heating the material too approximately 820-850C (1508 -1562 F) and held until the material reaches a uniform temperature. It should be soaked for one hour per 25 mm section of material and subsequently cooled in still air. 

High carbon steel

High carbon steels are those with carbon contents between 0.60% and 1.4% of the overall weight. The alloys in this particular category constitute the strongest and hardest within the three groups, but they are also the least ductile. These steels are used in a range of different mechanical, cutting and bearing applications as it can be hardened through heat treating and tempering. Additional alloys can be added to this steel category in order to generate different characteristics. Chromium and Manganese, for example, are used in the composition of 52100 steel and aid in the hardening process while enhancing the steel’s resistance to corrosion. Since 52100 is one of the steel grades frequently used to manufacture linear shafting, precise control of the case depth can be critical to generate a shaft with both a hardened surface (for loaded ball contact) and an un-hardened inner core which prevents the shaft from becoming brittle.

Steel alloys are given designators by organizations such as the American Iron and Steel Institute (AISI) and the American Society for Testing and Materials (ASTM) for easier classification and identification. AISI typically follows a four digit system, where the first two digits indicate the alloy, and the second two digits denote the carbon content. ASTM uses an “A” to denote ferrous materials, followed by an arbitrarily assigned number for each alloy.

Regardless of the system used, this standardization allows cross talk between designers, engineers, and builders to ensure the proper material is being selected and used in engineering projects. It also makes looking up physical properties of alloys very easy, as a simple search with the identification number produces the correct information.
