455 Round Bar

455 Round Bar stainless steel combines the amazing corrosion resistance characteristics, one-step age hardenability, ease of fabrication, and yield strength.

455 Round Bar Stainless Steel

455 round bar is a type of steel that is corrosion resistant.

In the field of precipitation-hardening stainless steel,  it is an advanced martensitic alloy used in production. It combines the amazing corrosion resistance characteristics, one-step age hardenability, ease of fabrication, and yield strength. It has three times greater characteristics than that of standard stainless grade 304. Thus, you can have all these incredible features in a single piece of material.

Stainless steel is excellent material for bar production. It is corrosion resistant, has high tensile strength, and is easily machined. The 455 stainless bars are used in a variety of industries such as the automotive, aerospace, and manufacturing sectors. 455 stainless bar is also used in the construction industry because it can withstand high temperatures without losing its properties.

The answer is quite simple. It is because of the quality and strength. You can get a lot more value for your money by buying a 455 stainless steel round bar.

Stainless steel has been used for decades, and it has continuously improved to meet the needs of different industries. When you buy a 455 stainless steel round bar, you will be able to use it without any issues

Machinability & Welding

As with other precipitation-hardenable stainless steels, this stainless steel can be machined while still in the annealed condition and welded similarly to other stainless steels.

Because of its low work-hardening rate, it can be cold formed significantly. During hardening, the dimensional change is only about -0.001 in/in, allowing close-tolerance finish machining while the material is still in the annealed state.


Aircraft parts and systems and medical instruments are just some of the many applications of 455 Stainless.
