What is Stainless Steel 303 Round Bar?
Stainless Steel 303 Round Bar is one of the most popular types of stainless steel. Parts that require precision machining and polishing are needed for these applications. One of the most widely used stainless steel varieties is the 303 round bar. The stainless steel grade 303 is a non-magnetic alloy with traces of sulfur. But it lessens its hardness.
Additionally, the machined surface quality is outstanding. It is the perfect material for several applications due to its low carbon content. In specific applications, it’s a fantastic substitute for carbon steel. The total 18% Chromium and 8% Nickel Stainless Steel is converted into this grade. Selenium, phosphorus, and sulfur have been added to improve their machinability.
What is Stainless Steel 304 Round Bar?
304 round bar is a form of stainless steel utilized extensively across numerous sectors. Due to its enhanced corrosion resistance, it is perfect for applications involving high temperatures. It is very easy to weld and has excellent machinability. They work well for both mining equipment and architecture. Stainless Steel 304 Round Bar has more chromium than carbon steel does.
It is less magnetic and has mechanical qualities similar to carbon steel. The austenitic 304 stainless round bar has a 12% to 18% chromium concentration and is made of austenitic material. It has a hardness of 58–60 HRC and is non-magnetic in the annealed condition. It also features a rust-resistant, dull mill finish that is semi-hard.
Difference between 304 Vs 303 SS Round Bars
304 and 304 Round Bars are two varieties of stainless steel that share a similar chemical makeup but differ in physical characteristics. They are perfect for various applications due to their toughness, corrosion resistance, and machinability. But before selecting an alloy for a particular application, there are several things to consider. While 303 and 304 both work well in typical corrosive applications, they are not suitable for settings with extreme acidity or chloride concentrations. For instance, you should pick an alloy less prone to pitting if your application is in the oil and gas sector.
With a minimum of 17% chromium and 8% nickel, the composition of SS 304 and 303 Round Bars is relatively similar. But 303 also has at least 0.15% sulfur in it. This sulfur contributes to increased machinability. The higher copper content in stainless steel improves the machinability and corrosion resistance of the material. Increased ductility is a feature of these stainless steels. But the work-hardening tendency is more substantial in grade 303. This implies that it might be more susceptible to weariness.
