AISI 430 ist ein ferritic stainless steel containing 16-18% chromium mit nein nickel addition, making es significantly mehr economical als 304. Unlike austenitic grades, 430 ist magnetic, hat unter thermal expansion (similar zu carbon steel), und cannot sein hardened durch heat treatment. Es provides gut corrosion widerstand in mild atmospheres, fresh wasser, und food contact applications. Widely used für automotive trim, appliance panels, kitchen ausrüstung, und architectural interiors. Unter formability als 304 limits deep-drawing applications, und es hat reduced weldability requiring post-weld annealing.

Frequently Asked Questions
Können 430 ersetzen 304 zu save kosten?
Ja, in applications wo corrosion requirements sind moderate (indoor, freshwater, nein chlorides) und magnetism ist acceptable. 430 ist 30-50% cheaper als 304 due zu zero nickel content. However, 430 cannot match 304's deep drawability, toughness bei niedrig temperatures, oder chloride pitting widerstand. Gemein substitution: 430 für indoor architectural panels, 304 für outdoor oder food-contact surfaces.
