Hot Sale Building iron rod price 2mm 5mm 4mm 8mm SS321 Stainless Steel Round Bar
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.
