Stainless Steel Square Bar
HIGH QUALITY PRODUCTS
Stainless Steel Square Bar
Stainless steel square bars are solid, long pieces of stainless steel with a square cross-section. They are made from steel alloys containing at least 10.5% chromium, which imparts excellent corrosion resistance. These bars are available in various sizes, grades, and finishes, making them suitable for a broad range of applications. The manufacturing process typically involves melting, casting, hot rolling, and sometimes cold finishing to achieve the desired dimensions and surface finish.

Typical Chemistry:
The chemical composition of stainless steel square bars varies depending on the grade, but a common example is the 304 stainless steel grade:
- Chromium (Cr): 18% to 20%
- Nickel (Ni): 8% to 10.5%
- Carbon (C): ≤ 0.08%
- Manganese (Mn): ≤ 2%
- Silicon (Si): ≤ 1%
- Phosphorus (P): ≤ 0.045%
- Sulfur (S): ≤ 0.03%
Other grades, like 316, 410, and 430, will have different compositions to provide specific properties such as increased corrosion resistance or hardness.
Physical Properties:
The physical properties of stainless steel square bars depend on the specific grade and processing methods, but typical properties include:
