Stainless Steel Round Bar

Stainless steel bars are made of stainless steel ingots by hot rolling or forging.

The production of stainless steel bar is rising with the development of stainless steel. As the application of stainless steel bars is more and more extensive, such as the foundation of high-rise buildings in cold areas, the isolation net beside the highway, household supplies, etc., the hot rolling production of stainless steel bars has been greatly developed, 30% of the stainless steel products in China, only 8% - 10% in foreign countries. With the rapid development of petroleum, chemical industry, energy and atomic energy, aerospace, ocean development and other cutting-edge technologies, higher comprehensive performance requirements are put forward for stainless steel, which not only requires good corrosion resistance, but also requires high strength, high temperature and pressure resistance, radiation resistance, low temperature resistance and other properties, so as to further develop the types of stainless steel.

The section shape of the bar is simple, which is much larger than the general section of the wire rod, so the heat dissipation is slow, the rolling time is allowed to be long, and the problem of large temperature difference between the head and the tail is not prominent, but the upper limit product is easy to be compressed. Like other hot rolling, in order to roll products with high dimensional accuracy, it is necessary to ensure uniform heating, high mill rigidity and consistent cooling during rolling. There are also wear in rolling which brings about the change of pass shape and affects the lasting stability of rolling.

Production process of stainless steel bar

Billet acceptance → heating → rolling → multiple scale shearing → cooling → shearing → inspection → packaging → metering → warehousing

According to the shape, it can be roughly divided into: stainless steel round bar, stainless steel square bar, stainless steel hexagon bar.

Production process and classification of stainless steel bars

Stainless steel bars are made of stainless steel ingots by hot rolling or forging.

According to the shape, it can be roughly divided into: stainless steel round bar, stainless steel square bar, stainless steel hexagon bar.

According to the surface treatment can be divided into: stainless steel black bar, stainless steel acid white bar, stainless steel bright bar, stainless steel grinding bar.
