434 stainless steel
Name: ferritic stainless steel
Standard: AISI, ASTM
Model: 434
UNS Number: S43400
● 434 properties and applications:
434 ferritic stainless steel. Chromium 12% to 30%. Its corrosion resistance, toughness and weldability with the chromium content increased with the increase, resistance to chloride stress corrosion better than other types of stainless steel. 434 (18Cr-1Mo) is a modified 430 steel steel, steel, salt-tolerant than 430 points, decorative materials for motor vehicles. Corresponding to the national standard 1Cr17Mo, JIS SUS434.
