06Cr18Ni13Si4 Stainless Steel Coil & Plate | GB/T 4237 06Cr18Ni13Si4（314) Stainless Steel Sheet Manufacturer & Exporter – Gangsteel

Gangsteel is a leading manufacturer and global exporter of GB/T 4237 06Cr18Ni13Si4 stainless steel hot-rolled coils, plates, and wide heavy plates. Internationally recognized as Grade 314 (also known as 314S or AISI 314), 06Cr18Ni13Si4 is a high-silicon, high-chromium, high-nickel austenitic heat-resisting stainless steel specifically engineered for exceptional resistance to oxidation, carburization, nitridation, and cyclic thermal fatigue at very high temperatures — continuous service up to 1150°C and intermittent up to 1200°C in oxidizing atmospheres.

With 23–26% Cr, 19–22% Ni, and significantly elevated silicon (1.5–3.0%), 314 forms an extremely stable and protective silicon-chromium oxide scale that provides outstanding scaling resistance and carburization protection in high-temperature furnaces, incinerators, and process equipment where standard heat-resisting grades like 310S fail due to severe oxidation or carburizing conditions.

Produced under GB/T 4237-2015 (Stainless Steel Hot-Rolled Sheets and Strips), Gangsteel supplies 06Cr18Ni13Si4 in thicknesses from 2 mm to 500 mm and widths up to 4200 mm — one of the widest hot-rolling capabilities available worldwide. Our products are delivered in standard hot-rolled finishes No.1 (annealed & pickled) and 2D (annealed & pickled dull) and are exported globally to petrochemical, power generation, cement kiln, waste incineration, glass melting, ceramic kiln, and high-temperature furnace industries.

Why Choose Gangsteel for 06Cr18Ni13Si4 (314) Hot-Rolled Stainless Steel?

Gangsteel’s wide heavy-plate rolling mills enable single-piece production of large radiant tubes, furnace muffles, retorts, calciner shells, burner nozzles, and high-temperature conveyor belts, minimizing welds and maximizing service life in extreme oxidizing and carburizing environments. We maintain strict control over silicon and annealing to ensure consistent high-temperature scaling resistance and creep strength.

Key Insight: 06Cr18Ni13Si4 (314) provides superior oxidation and carburization resistance than 310S due to high silicon content (1.5–3.0%).

Manufacturing Process: Hot Rolled at Gangsteel

Gangsteel's hot-rolling process for 06Cr18Ni13Si4 includes:

1. Electric arc furnace + AOD refining → precise high-Si high-Cr/Ni control
2. Continuous casting into wide slabs
3. Reheating to 1150–1250°C
4. Hot rolling on wide heavy-plate mills (up to 4200 mm width)
5. Controlled cooling, leveling, and descaling
6. Solution annealing + pickling for No.1 finish or shot blasting + pickling for 2D finish
7. Edge trimming, coil splitting, or cut-to-length

Thickness range: 2 mm – 500 mm Width range: up to 4200 mm Length: up to 18 m (plate) or coil form

Finishes: No.1 (annealed & pickled), 2D (annealed & pickled dull)

Available Forms, Sizes, and Specifications

• Hot-rolled coils: 2.0–25.0 mm thick, up to 4200 mm wide
• Hot-rolled plates: 2.0–500 mm thick, up to 4200 mm wide × 18 m long

Key Applications of 06Cr18Ni13Si4 (314) Hot-Rolled Products

• Radiant tubes, muffles, retorts, and annealing covers in high-temperature furnaces
• Petrochemical reformers, crackers, and pyrolysis coils
• Cement kiln preheaters, calciners, and clinker coolers
• Waste incinerators and high-temperature exhaust systems
• Glass melting furnaces and ceramic kiln components
• Power generation superheater tubes and burner nozzles

Advantages of Choosing 06Cr18Ni13Si4 (314)

• Exceptional oxidation and scaling resistance up to 1150°C continuous
• Superior resistance to carburization and sulfidation
• Good creep and rupture strength at very high temperatures
• Weldable with low carbon for reduced intergranular corrosion risk
• High silicon for enhanced oxide adherence and thermal fatigue resistance
• Cost-effective ultra-high-temperature grade vs. nickel alloys
• Wide acceptance in furnace and incineration industries

Corrosion and Oxidation Resistance

High Si + Cr/Ni forms an extremely adherent oxide scale; excellent in oxidizing atmospheres, resists carburization/sulfidation. Low carbon minimizes sensitization. Oxidation resistance ~1150°C continuous, ~1100°C cyclic.

Weldability and Fabrication

Good weldability with TIG/MIG; low carbon reduces sensitization. Use ER314 or ER310 fillers. High ductility supports forming; annealing may be needed post-weld for critical uses.

FAQ

Q1: What is the main advantage of 314 (06Cr18Ni13Si4) over 310S?

A: 314 has significantly higher silicon (1.5–3.0% vs. ≤1.5% in 310S), forming a much more protective and adherent oxide scale, providing superior oxidation, carburization, and thermal fatigue resistance at temperatures above 1000°C.

Q2: Can 06Cr18Ni13Si4 be used in reducing or carburizing atmospheres?

A: Yes, it performs very well in carburizing and mildly sulfidizing environments due to high Si + Cr/Ni; for severely reducing conditions, nickel alloys (e.g., 800H) may be better.

Q3: What finishes are available under GB/T 4237 for hot-rolled 314?

A: Standard finishes are No.1 (annealed & pickled) and 2D (annealed & pickled dull). No.1 is most common for further processing.

Q4: What is the maximum width and thickness Gangsteel can produce for 06Cr18Ni13Si4?

A: Up to 4200 mm wide and 500 mm thick in hot-rolled plates; coils typically 2–25 mm thick.

Q5: Is 314 weldable? What filler should be used?

A: Yes, good weldability. Use ER314 or ER310 fillers to match high-temperature properties.

Q6: Does Gangsteel offer third-party inspection for GB/T 4237 314 material?

A: Yes — SGS, TUV, BV, or customer-nominated agencies are welcome at any stage.

Q7: What is the lead time for hot-rolled 06Cr18Ni13Si4 coils or plates?

A: Standard sizes from stock: 7–15 days. Custom wide/heavy plates: 25–45 days depending on thickness and quantity.

Q8: Can Gangsteel provide 314 with BA or 2B finish?

A: Hot-rolled material is No.1 or 2D. For BA or 2B, we supply cold-rolled versions under GB/T 3280.
