430 stainless round bar (ASTM A276; GB 10Cr17) is a ferritic stainless steel with a chemistry focused on cost-effectiveness over corrosion resistance: 16.0–18.0% chromium (Cr),<=0.12% carbon (C),<=1.00% manganese (Mn),<=0.75% silicon (Si) ve 304 gibi östenitik derecelerden farklı olarak - nikel yok.
Yüksek krom içeriği, kuru ortamlarda ılımlı korozyon direnci sağlar, ancak klorür - zengin ayarlarla mücadele eder. Its mechanical properties include 450–600 MPa tensile strength, 205 MPa yield strength, and 20% elongation, making it suitable for decorative trim, kitchen utensils, and automotive trim-applications where appearance matters more than extreme corrosion resistance. 430 is 30–40% cheaper than 304, with - Çin listelerinde - yapıldı "430 paslanmaz yuvarlak çubuk - ekonomik dekoratif sınıf" olarak pazarlanıyor.
