ASTM A240 430 Stainless Steel Coil - Ferritic BA Finish

Grade 430 is a straight chromium ferritic stainless steel offering good corrosion resistance combined with excellent formability. As a magnetic stainless steel grade, it provides an economical alternative to austenitic grades like 304 for applications where high corrosion resistance is not the primary requirement.

Key Features

• Magnetic Properties: Ferritic microstructure provides magnetic properties ideal for induction-compatible applications and magnetic attachment systems
• Bright Annealed BA Finish: Controlled atmosphere annealing produces a highly reflective, aesthetically pleasing surface without pickling
• Cost Effective Alternative: Nickel-free composition offers significant cost advantage over 304/316 grades while maintaining practical corrosion resistance
• Excellent Deep Drawability: Superior stretch-forming characteristics making it ideal for complex formed shapes
• Good Oxidation Resistance: Effective protection against scaling in intermittent service up to 870°C
• Thermal Conductivity: Higher thermal conductivity than austenitic grades provides better heat distribution in appliance applications

Typical Applications

• Home appliance panels and trim (refrigerators, dishwashers, washing machines)
• Automotive exterior and interior trim components
• Elevator cabin panels and escalator cladding
• Indoor architectural decorative panels
• Kitchen exhaust hoods and ventilation systems
• Consumer electronics casings

Quality Assurance

Each coil undergoes spark emission spectrometry for grade verification, surface quality inspection under controlled lighting, tensile and hardness testing, and Erichsen cupping test for formability validation. Material certificates to EN 10204 3.1 standard provided.
