Product Description
439 Stainless Steel Bar Description
439 stainless steel bars have a high chromium content that can prevent rust and corrosion in both wet and dry conditions. This makes them an ideal option in environments where moisture or chemicals exist. In addition, Good formability and weldability means they can be easily molded into different forms or sizes without sacrificing the structural integrity. This makes them applicable for a variety of manufacturing processes. However, 439 stainless steel bars are prone to corrosion in certain environments. Contact with substances containing chloride, such as salt water or harsh cleaners, can cause pitting and rust on the surface. For another, 439 stainless steel bars may not have the same level of strength and durability as other stainless steel bars. Although it is still a strong material, it may not perform well under heavy loads or stressful conditions.
