ASTM A240 904Lsteel plate Performance, chemical composition and welding

ASTM 904L steel plate equivalent to ASME SA-240 N08904, EN: 1.4539, varies by application C content <= 0.02% or 0.03% High chromium content and sufficient nickel content, copper The addition of it gives it a very strong acid resistance, especially resistance to chloride clearance and stress corrosion cracking. ASTM 904L steel plate is katalor’s main steel and have experience on supplying ASTM 904L steel plate.

ASTM 904Lsteel plate ingredients are as follows:
C 0.06Max; Si 1.0Max; Mn 2.0Max; P 0.045Max; S 0.030Max; Cr 19.0--21.0
Ni 24.0--26.0; Mo 4.0-5.0; Cu 1.0-2.0.

ASTM 904L steel plate Mechanical properties:
Tensile strength: ≥ 490MPa Yield strength: ≥ 220 MPa Elongation: ≥ 35%

ASTM 904Lsteel plate Welding Precautions:
ASTM 904Lsteel plate is a single phase austenitic structure, high Ni low C stainless steel, prone to hot cracking during welding, especially craters.
1, control of base metal and welding consumables in the S P and other harmful elements.
2, a large groove, small fusion than.
3, small heat input, not allowed to swing; 4, between the layers temperature ≤ 60 ℃.
5, a reasonable order of welding to reduce welding stress.
6, use low hydrogen welding consumables.
7, welding arc welding place after welding, to avoid crater cracks.
8, the back of the root cleaning, carbon arc gouging is not allowed to prevent carburizing.

ASTM 904Lsteel plate welding material one:
Welding wire Ni182 φ2.4 (GB / T 15620-1995)
Electrode Ni370B (ENiCrFe-3 AWS A5.11-90)

ASTM 904Lsteel plate welding material two:
GTAW Wire: Sandvik W20.25.5LCu (Sweden) Meets ASME SFA5.9 ER385
Its chemical composition is as follows:
C≤0.020 Si≤0.4 Mn = 1.0-2.5 Cr = 19.5-21.5 Ni = 24.0-26.0
Mo = 4.2-5.2 Cu = 1.0-2.0 P≤0.015 S≤0.015
ASTM 904Lsteel plate deposited metal mechanical properties:
Tensile strength: ≥ 520MPa Yield strength: ≥ 250 MPa Elongation: ≥ 35%

ASTM 904Lsteel plate welding material selection three:
ASTM 904L composite board transition layer can choose A042

ASTM 904Lsteel plate welding consumables choice four:
Domestic GTAW wire: H02Cr20Ni25Mo4Cu (YB / T5092-2005) equivalent to ER385
