321 Stainless Steel Bar
Stainless Steel Bar is one type of a product made in the stainless steel materials. There are different grades of stainless steels used in various industries. Stainless steel bars are used for their strength and corrosion resistance properties. All stainless steels contain chromium. The composition can vary and the chromium content varies as well. The more the chromium content, the high the corrosion resistance is.

PRODUCT DETAILS


321 Stainless Steel Bar Rod manufacture

 

Grades 321 and 347 are the basic austenitic 18/8 steel (Grade 304) stabilized by Titanium (321) or Niobium (347) additions. These grades are used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850 °C. Grade 321 is the grade of choice for applications in the temperature range of up to about 900 °C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion.

A limitation with 321 is that titanium does not transfer well across a high-temperature arc, so it is not recommended as a welding consumable. In this case grade 347 is preferred - the niobium performs the same carbide stabilization task but can be transferred across a welding arc. Grade 347 is, therefore, the standard consumable for welding 321. Grade 347 is only occasionally used as parent plate material.

Grade 321H is a modification of 321 with higher carbon content, to provide improved high-temperature strength.
