Product Description

Stainless steel bars are made of stainless steel ingots, hot rolled or forged.

The production of stainless steel bars has arisen with the development of stainless steel. Due to the wider application range of stainless steel bars, such as the foundation of high-rise buildings in cold areas, the isolation nets next to highways, household household goods, etc., the hot rolling production of stainless steel bars has been greatly developed.


Bars account for China's stainless steel. 30% of products account for only 8%-10% in foreign countries. With the rapid development of cutting-edge technologies such as petroleum, chemical, energy and atomic energy, aerospace and marine development, higher comprehensive performance requirements for stainless steel are required, which not only requires good corrosion resistance, but also requires high strength, high temperature and high pressure. The anti-radiation and low-temperature resistance properties have further developed the types of stainless steel.

Production Process and Feature

Stainless steel bar production process and classification

Stainless steel bars are made of stainless steel ingots, hot rolled or forged.
According to the shape, it can be roughly divided into: stainless steel round bar, stainless steel square bar, stainless steel hexagonal bar.

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

Stainless steel bar Common furnace type for melting
Several types of furnaces are commonly used. At present, the domestic bar or bar production line uses heat treatment equipment for alloy steel and chrome steel series products: roller hearth furnace (tunnel furnace), trolley furnace, hood furnace, slow cooling pit.

Common problem while produce stainless steel bar

Because there is no slow cooling and annealing facilities, the rolled bars are directly exposed to the air and cooled, causing the following six major problems:
1 surface cracks on the surface of the bar, cleavage defects in the internal structure;
2 energy waste, long annealing cycle;
3 The production logistics organization is not smooth, the products are frequently dumped on the site, the transportation cost is increased, the labor intensity of the post workers is high, and the bar process damages the bar;
4 due to many product defects, it is necessary to inspect one by one, the inspection work is heavy and the inspection cost is increased;
5 product delivery cycle is long;
6 product yield rate is low, customer quality objection
