321 Stainless Steel Round Bar can be categorically said that steel bars are one of the core components of any manufacturing industry or for that matter any industry that relies on machineries. versatile applications in automotive, textile, fabrication, construction, cement, ship building, paper and pulp, defence, heavy earth moving equipments or aerospace.
Grade 321 Stainless Steel is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 321 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "321DDQ" (Deep Drawing Quality) variants.
