What are the benefits of hot rolled steel? Hot rolled steel can often be identified by the following characteristics: A scaled surface—a remnant of cooling from extreme temperatures Slightly rounded edges and corners for bar and plate products (due to shrinkage and less precise finishing) Slight distortions, where cooling may result in slightly trapezoidal forms, as opposed to perfectly squared angles Hot rolled steel typically requires much less processing than cold rolled steel, which makes it a lot cheaper. Because hot rolled steel is allowed to cool at room temperature, it’s essentially normalized—meaning it’s free from internal stresses that can arise from quenching or work-hardening processes. Hot rolled steel is ideal where dimensional tolerances aren’t as important as overall material strength, and where surface finish isn’t a key concern. Where surface finish is a concern, scaling can be removed by grinding, sand blasting, or acid-bath pickling. Once scaling ha

Hot rolled steel typically requires much less processing than cold rolled steel, which makes it a lot cheaper. Because hot rolled steel is allowed to cool at room temperature, it’s essentially normalized—meaning it’s free from internal stresses that can arise from quenching or work-hardening processes. Hot rolled steel is ideal where dimensional tolerances aren’t as important as overall material strength, and where surface finish isn’t a key concern. Where surface finish is a concern, scaling can be removed by grinding, sand blasting, or acid-bath pickling. Once scaling has been removed, various brush or mirror finishes can also be applied. Descaled steel also offers a better surface for painting and other surface coatings.

Quenching and tempering are processes that strengthen and harden materials like steel and other iron-based alloys. The process of quenching or quench hardening involves heating the material and then rapidly cooling it to set the components into place as quickly as possible. The process is tightly controlled, with the heating temperature, cooling method, cooling substance and cooling speed all dependent upon the type of material being quenched and the desired hardness. A typical heating range is between 815 and 900 degrees celcius, with extra care being taken to keeping the temperature as stable as possible. Variances in the degree of heat being applied during the process can result in distortion in the resultant metal. Likewise, the temperature of the cooling element needs to remain constant or the edges of the metal can wind up brittle. Different cooling elements have come into prominence over the years, naturally starting with water and moving onto mineral oils and even inert ga

I t’s important to note that the main difference between hot rolled and cold rolled steel is one of process. “Hot rolling” refers to processing done with heat. “Cold rolling” refers to processes done at or near room temperature. Although these techniques affect overall performance and application, they should not be confused with formal specifications and grades of steel, which relate to metallurgical composition and performance ratings. Steels of different grades and specifications can be either hot rolled or cold rolled—including both basic carbon steels and other alloy steels. It may seem obvious, but some types of steel are better suited for certain applications. Knowing which to use can help avoid over-spending on raw materials. It can also save time and money on additional processing. Understanding the differences between hot and cold steel is integral to choosing one over the other. HOT ROLLED STEEL   Hot rolled steel is steel that has been roll-pressed at very

While hydraulic power transmission is extremely useful in a wide variety of professional applications, it is generally never wise to depend on one form of power transmission. Each different type of power transmission (electrical, mechanical, and fluid) works best when integrated into an overall power transmission strategy. You should invest in finding honest and skilled hydraulic manufacturers / suppliers who can assist you in developing and implementing an overall hydraulic strategy. With specific regard to hydraulic cylinders, it is important to note that all cylinder components must be made of durable materials that can withstand the friction and heat created by the use of the hydraulic cylinder. Stamping or extrusion processes are used to produce seals which are made of nitrile rubber, viton, polypropylene, brass or stainless steel depending on the application. The pistons are made of brass, steel, stainless steel, aluminum, cast iron, or bronze. Piston rods and cylind

ST52 chrome plated honed tube  is used for the production of mechanical parts. Its precision requirements are high, so it must be said that complicated process and strict inspection can be delivered, and with the continuous development of technology, the production process of honing pipe is constantly improving. perfect. In order to make the production efficiency of ST52 electroplating honing pipe high, we have adopted a new production process, which is produced by grinding and automatic grinding. Among them, automated grinding includes the use of electric or ultrasonic grinding to complete production tasks. The daily working principle of the ST52 electroplating honing pipe is mainly the pressure generated by the sand on the belt, and the surface grinding under the rotation speed. After the upper and lower movement of the abrasive belt, the upper and lower surfaces of the workpiece are grounded back and forth to achieve the effect. Of course, in the grinding process, it is nec

The honed cylinder tubes which are processed by Skiving & Roller Burnishing have a surface residual compressive stress left on the surface layer, which contributes to the sealing of the surface micro crack and hinders the expansion of the erosion effect. Thereby, the surface corrosion resistance is improved, and the generation or expansion of the fatigue crack can be delayed, thereby improving the fatigue strength of the honed tube. Through Roller burnish forming, the rolling surface forms a cold hardening layer, which reduces the elastic and plastic deformation of the grinding contact surface, thereby improving the wear resistance of the inner wall of the honing pipe and avoiding burns caused by grinding. After rolling, the inside surface roughness value of honed tube is reduced, which can improve the tolerance fit property. After knowing the advantages of the honing process compared to Skiving & Roller burnishing process, people can easily determine which manufacturi
