Product Details

Item: Ferritic Stainless Steel

Standard: AISI、ASTM

Grade: 434

UNS No.: S43400


Feature and Application: 

434 ferritic stainless steel. Contains 12% ~ 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content. 434(18Cr-1Mo) is an improved steel grade of 430 steel, which is more resistant to salt than 430 steel. Equivalent to GB standard 1Cr17Mo and JIS Standard SUS434.


434 Chemical Composition: 

C: ≤0.12

Mn: ≤1.00

Si: ≤1.00

Cr: 16.0~18.0

Ni: —

P: ≤0.04

S: ≤0.03

Mo: 0.75~1.25


SUS434 is one of the JIS SUS series ferritic stainless steel. SUS434 stainless steel contains 12% ~ 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content. Resistance to chloride stress corrosion is better than other kinds of stainless steel. SUS434(18Cr-1Mo) is an improved steel grade of 430 steel, which is more resistant to salt than 430 steel. Equivalent to GB standard 1Cr17Mo, ASTM standard 434, DIN standard X6CrMo17, BS standard 434S19, NF standard Z8CD17-01.
