What is S460ML=Z35 EN 10025-4 Z35 Through-Thickness Plate?

S460ML=Z35is a thermomechanically rolled (TMCP) weldable fine-grain structural steel under EN 10025-4:2004 (2019 revision) with additional Z35 through-thickness quality per EN 10164 Class 3.

S460ML= structural steel, 460 MPa yield, TMCP delivery, low-temperature toughness (–50 °C)
=Z35= guaranteed through-thickness ductility: minimum 35 % reduction of area (RA_z) in Z-direction tensile test (three specimens per heat, average ≥35 %, single ≥25 %)

Z35 quality prevents lamellar tearing in highly stressed welded joints where tension acts perpendicular to the plate surface (T-joints, cruciform welds, gusset plates, jacket leg nodes, etc.).

S460ML=Z35 is the preferred grade for:

Offshore wind jackets and monopile transition pieces
Jack-up rig leg chords and rack plates
Heavy crane base and boom sections
Seismic-resistant building columns
Thick plate welded structures under high Z-direction stress

FAQ

Q1: What is Z35 in S460ML?

A: Z35 = ≥35% reduction of area in Z-direction tensile test (EN 10164 Cl.3), preventing lamellar tearing in welds under perpendicular stress. Mandatory for T-joints in offshore jackets.

Q2: S460ML=Z35 vs S460ML difference?

A: Z35 adds through-thickness guarantee (RA_z ≥35%); standard S460ML is Z25 (≥25%). Yield/impact same—Z35 for high-risk welds.

Q3: Welding preheat for S460ML=Z35?

A: None to 80 mm (CEV 0.42-0.46); low-H E7018 H4. Thicker: 75-120 °C (EN ISO 13916). TMCP preserves Z35 in HAZ.

Q4: S460ML=Z35 for pressure vessels?

A: Yes, PED III (EN 13445); derate >63 mm. UT S3/E3; RT opt seams. Z35 aids nozzle welds.

Q5: Z35 price premium?

A: +20-40 USD/t vs standard S460ML; included in our Z35 stock.

Q6: ASTM equiv for S460ML=Z35?

A: A913 Gr.65 + Z35; yield 450 MPa, Z35 –50 °C. Dual-cert stocked.

Q7: Custom S460ML=Z35 lead time?

A: Stock 1-3 days; processed 2-5 days; mill 3-5 weeks. 95% OTIF; air <10 MT 24-48 hrs.
