A variety of methods can produce  stainless steel profiles , all of them offering different benefits. Hot rolled profiles have some very specific characteristics as well. Rolling of profiles can take place at high temperatures (hot rolling) or at room temperature (cold rolling). The temperature plays a significant role in regards of the result. With both production technologies, it is possible to produce either hot rolled profiles or cold rolled profiles in stainless steel. However, the properties of both methods show distinct differences. Hot Rolled Profiles – When Stainless Steel Heats Up Hot rolling of sections is the most productive technology of manufacturing long bars. Once the mill is set-up and ready for the production process, it can hot roll profiles in huge amounts with high productivity. In general, the temperature rises above 1.100 degrees Celsius. So the billets or blooms for the traditional “start-stop”-production method or wire rods for “endless” rolling ...

Stainless steel is a versatile material made of steel alloys and a small percentage of chromium. It is mainly preferred for its low-maintenance and oxidant resistant feature. It is widely used in piping and piping and tubing manufacturing. Stainless steel pipes are used in equipment like instrumentation, automobiles, surface condensers, fluid piping, and evaporators. Stainless steel delivers the features of high strength, toughness, and corrosion resistance. It mainly used for applications that require internal pressure within the process equipment and water treatment applications. Stainless steel pipes are used in applications like – • Synthetic fibers • Water treatment facilities • Modern architecture • Oil and gas processing • Fertilizers • Textile machinery • Power plants • Construction • Pesticides Based on the usage these stainless steel pipes are broken down into several categories – Stainless Steel Piping – Pipes and tubes are classified and distinguished on functions. ...

Stainless steel angle bar  is a long steel bar with angles on both sides. There are equilateral stainless steel angle and unequal stainless steel angle. The two sides of an equilateral stainless steel angle are equal in width. Its specifications are expressed in mm of side width × side width × side thickness. Example "∠25 × 25 × 3", which means an equilateral stainless steel angle with a side width of 25 mm and a side thickness of 3 mm. Mainly used for metal components and the frame of factory buildings. It requires good weldability, plastic deformation performance and certain mechanical strength in use. What factors influence its price?  1. Market Demand Driven by economic developing, the world's stainless steel production capacity has increased significantly. The production center of stainless steel has been transferred from developed countries in Europe and America to Asia, especially in China. With increasing in stainless steel production in Asia, the current...

When it comes to the using place of colored stainless steel sheets , most people will think of construction sites, factories and prefab houses. There is no doubt that colored stainless steel sheet is widely used in these places, but it also start to play a more and more important role in other areas which is close to our daily life. There are unlimited possibilities of the use of colored stainless steel sheet due to its great characteristics.   Besides construction sites and factories, colored stainless steel sheet is mainly used in  transportation industry, electrical industry and decoration industry. Coatings of colored stainless steel sheets which used in these distinguished sectors are slightly different, but the basic manufacturing technique is nearly the same. In the transportation industry, colored stainless steel sheet mainly plays a decorative role. They  may also be used as basic components of some simple accessories. In land transportation industr...

10% TO 15% SAVING OF MATERIALS BY USING H-BEAM   H-beam steel  is an economical section steel with more optimized section area distribution and more reasonable strength-to-weight ratio. Nowadays, H-beam steels have been widely used in today's steel structure construction. Compared with its competitor I-beam steel, H-beam steel profile has many advantages, among which the most significant one is its mechanical properties per unit weight. This allows construction side to cut costs and speed up building process. So how do H-beams steels do this? To the naked eye, the H-beam and I-beam steels have a similar appearance. But the differences in flange and two outside beams give H-beam steel a great performance advantage. On the one hand，There is no inclination in the inner surface of H-beam steel. Its upper and lower surfaces are parallel, and the inner edge has uniform thickness. Those characteristics bring better torsion resistance for H-beam steel, as well as the reas...

What is PVD coating ? PVD stands for Physical Vapor Deposition. PVD Coating refers to a variety of thin film deposition techniques where a solid material is vaporized in a vacuum environment and deposited on substrates as a pure material or alloy composition coating. PVD coatings surpass traditional electroplated coatings, it's more corrosion resistant and have superior hardness. The process of PVD coating During the process, first of all the stainless steel is cleaned to make sure that the coating will bond well. The steel is then placed in a vacuum chamber with a “target” metal; this will be used to create the coating. A high vacuum level is needed in the coating chamber, then a small amount of argon gas is introduced. A high voltage circuit is used in order for the stainless steel and target to bond or adhere. This allows the argon ions to bombard the target to release atoms of the target metal, which are deposited on the stainless steel substrate as the coating. This PVD p...

SPOT NICKEL PREMIUM TO NARROW IN THE NEAR FURTHER     Nickel is the essential allying element in the 300 series  stainless steel grades . The presence of nickel results in the formation of an “austenitic” structure that gives these grades their strength, ductility and toughness, even at cryogenic temperatures. It also makes the material non-magnetic. While the role of nickel has no direct influence on the development of the “passive” surface layer, it results in significant improvement in resistance to acid attack, particularly with sulfuric acid. So that the price of nickel affected the price of stainless steel.   Nickel price continued to trend high. Spot nickel premium is likely to narrow further and some market participants are likely to remain on the sidelines. Nickel on the LME ended the weekend in a volatile session following copper after a first-phase trade deal between China and the US dispelled concerns about the health of the global economy...
