303 Stainless Steel Round Bar

Tensile strength, 85,000 PSI, and yield strength, 45,000 PSI, are two of the mechanical characteristics of 303 stainless steel round bars. These round bars have a 50% maximum elongation. Rockwell B Hardness, which has a value of 180, is another attribute. However, this alloy grade’s corrosion resistance is often less than grade 304. Sulfur is added to round bars of this grade, which enhances their machinability, but it also has certain downsides. First of all, the alloy loses some of its corrosion resistance. The qualities of its hardness are next little degraded.

Additionally, the sulfur-containing areas in the microstructure of ASTM a276 type 303 bar operate as pitting-initiating zones for corrosion. However, the alloy shows high resistance to oxidation up to temperatures of 927°C for both interrupted and continuous usage. However, due to the greater carbon content, which encourages carbide precipitation, manufacturers do not advise utilizing these round bars at temperatures above 760°C. Unlike 303 stainless steel welding rods, lower carbon-containing alloys are resistant to getting sensitized. Consumers might use the round bars to weld this material with the help of stainless-steel grade 310 electrodes, even though welding this material is not advised. The benefits of annealing this alloy include dissolving carbide precipitates and the development of a high machining rate. The ss 303 brilliant bar’s hardness rating ranges from 200 to 240 Brinell. Bar’s product lines follow the necessary production requirements and national and international quality standards. Additionally, these bars undergo several production steps while preserving their thickness and smoothness.
