Stainless steel bars are hot rolled or forged from stainless steel ingots. The production of stainless steel bars is rising with the development of stainless steel. The hot rolling production of stainless steel bars has been greatly developed due to the increasingly extensive application of stainless steel bars, such as the foundation of high-rise buildings in cold regions, the isolation network beside highways, household appliances, etc.

With the rapid development of cutting-edge technologies such as petroleum, chemical industry, energy, atomic energy, aerospace, and marine development, higher comprehensive performance requirements are put forward for stainless steel, which requires not only good corrosion resistance but also high strength, high temperature, and high-pressure resistance, radiation resistance, low-temperature resistance, etc., so that the varieties and types of stainless steel are further developed.

Application of Stainless Steel Bars

Stainless steel bars are mainly used for aircraft engine blades, casings, fasteners, combustion chambers, discs, shafts, combustion chamber outer walls, liquid oxygen kerosene engines, bullet bodies, steam cylinders, propulsion devices, etc. It is widely used in aerospace, aviation, atomic energy, nuclear energy, petroleum, chemical industry, food, environmental protection, marine development, boiler heat exchanger, and other fields.

Types of Stainless Steel Bars

Stainless steel bar is a kind of simple sectional profile, which is generally delivered in straight strip form. The varieties of bars can be divided into a round, square, hexagon, and deformed steel bars for construction according to the section shape. The latter is a periodic section, sometimes called ribbed steel bars. The main section shape of the bar is round.

The section shape of the bar is simple, which is much larger than the general section of the wire, so the heat dissipation is slow, the allowable rolling time is long, and the problem of the large temperature difference between head and tail is not prominent, but the upper limit product is easy to have insufficient compression ratio. As with other hot rolling, in order to roll products with high dimensional accuracy, it is necessary to ensure uniform heating, high rolling mill stiffness, and consistent cooling during rolling. There are also changes in pass caused by wear during rolling, which affect the lasting stability of rolling.
