303 Stainless Steel Hex Bar

303 Stainless Steel Hex Bar are easy cutting stainless steel bars with hexagonal shapes,suit for automatic-lathes for cutting and turning to different hex fittings and special hex support parts and hex tubes
SUS303 stainless steel hexagonal bars sizes 5-60mm supply usually,special sizes customed
ASTM303 hex steel bars,solid bars also,some times 304 hex bars usually instead 303 hex bars especially stainless steel hex tube,hollow bars because easier to get the raw pipe billets for 304 bars
303 hex bars Surface could be cold drawn,polished or sand balsting or acid washing
Welcome contact us for 303 hex bars inquiry
Availability:
Quantity:
  • 5-60mm flat to flat sizes
  • RuiYang

303 Stainless steel hex bars with hexagonal cutting shape,cold drawn with moulds tooling suit for various sizes and length,precision sizes,tolerance customed and good surface of your choice

Comparing 304 hex bars mainly different is S% higher and become easier cutting and soft,easy to drill and turning,also with 303 Cu stainless steel round bars and 303Cu hex stainless steel bars,making ss hex nuts and stainless steel hex head bolts and related products.

Same material like ASTM416,430F easy cutting steel,In china marked Y1Cr18Ni9

With our cold drawn workshop better guarantee the quality inside and soonest delivery to China port for section stainless steel products and cnc parts,our 303 hex bars details as below in table
