Deep Drawing Grade 430 Stainless Steel Coil with BA 2B Finish for Washing Machine Drums in 0.5mm-2.5mm Thickness

This deep drawing quality 430 stainless steel coil is specifically formulated for the production of washing machine drums, inner tubs, and spin baskets where a single blank must be drawn into deep cylindrical forms without tearing, orange peel, or surface defects.

The 430 ferritic grade combines moderate strength with excellent elongation, allowing deep progressive drawing operations used by home appliance manufacturers to produce seamless drum bodies with consistent wall thickness. A fine grain annealed microstructure, achieved through tightly controlled cold rolling and batch annealing, provides uniform plastic flow that deep draw tooling demands.

• Deep Drawing Performance: High elongation and fine grain structure support multi-stage drum forming without cracking
• Consistent Wall Thickness: Precise gauge tolerance prevents thinning zones in deep drawn cylindrical bodies
• Detergent Resistance: Chromium passive layer withstands alkaline detergents, softeners, and bleach cycles
• Surface Quality: Clean 2B or BA surface minimizes die pickup and delivers smooth drum interiors
• Low Work Hardening: Predictable strain behavior reduces springback and tool adjustment during high-speed pressing
• Appliance Grade Economy: Low nickel ferritic chemistry controls material cost for volume white goods production
• Full Traceability: Baosteel or TISCO base coils with Mill Test Certificate for every delivery

This deep drawing 430 coil is engineered for washing machine drum blanks, inner tub bodies, spin baskets, pulsator plates, and dryer drums used in front load and top load laundry machines.
