ASTM A815 Manufacturer | Supplier | Exporter in India | Duplex & Super Duplex

ASTM A815 Stainless Steel Pipe Fittings Manufacturer in India | Duplex & Super Duplex Exporter

Dipti Metal Industries – Largest & Top Leading ASTM A815 Manufacturer, ASTM A815 Supplier, ASTM A815 Exporter, ASTM A815 Dealer, ASTM A815 Stockist & ASTM A815 Wholesaler

Since 2009, Dipti Metal Industries has manufactured and exported ASTM A815 stainless steel butt-weld fittings in ferritic, ferritic/austenitic (duplex & super duplex), and martensitic grades. We supply global EPCs, OEMs, and distributors with seamless & welded fittings produced under strict QMS and delivered with full traceability (EN 10204 3.1/3.2).

✅ What is ASTM A815?

ASTM A815/A815M covers wrought stainless steel butt-welding fittings in corrosion-resistant grades. It specifies seamless and welded construction and defines WP (wrought) classes and CR (corrosion-resisting, light-weight) categories.

  • 🛠 Class WP-S: Seamless fittings

  • 🧪 Class WP-W: Welded, welds examined per spec

  • 🔎 Class WP-WX: All welds radiographed

  • 📡 Class WP-WU: All welds ultrasonically examined

  • 🧩 Class CR: MSS SP-43 light-weight, corrosion-resisting fittings

🧾 Available Grades (ASTM A815)

Ferritic: S43000, S44600, S44627
Duplex / Super Duplex (Ferritic/Austenitic): S31803, S32205, S32750, S32760, S32950, S39274, S32550, S32101, S32202
Martensitic: S41000, S41008, S41500

📌 Duplex/Super Duplex advantages: higher strength-to-weight ratio, superior pitting/crevice resistance in chlorides, better SCC resistance vs. 300-series austenitics—ideal for seawater, brine, sour service utilities (case-by-case).

🧪 Typical Properties Snapshot (Guide)

Properties vary by grade; below is a quick orientation:

  • Duplex/Super Duplex: High yield strength, excellent chloride pitting/crevice resistance, good SCC resistance

  • Ferritic: Good stress corrosion resistance, scaling resistance, magnetic

  • Martensitic: High hardness/strength after heat treatment, for wear-/erosion-related service (evaluate corrosion media)

🔬 Final selection should consider medium, temperature, pressure, chlorides, H₂S/CO₂, fabrication history, and code.

📚 FAQ – ASTM A815 Pipe Fittings

Q1. What is ASTM A815?
It is the specification for wrought stainless steel butt-welding fittings in corrosion-resistant grades, covering seamless and welded construction and defining WP and CR classes.

Q2. What do WP and CR classes mean?
WP classes (WP-S / WP-W / WP-WX / WP-WU) define product form and the extent of weld examination. CR refers to light-weight, corrosion-resisting fittings manufactured to MSS SP-43 for low-pressure service.

Q3. Which grades are commonly DIPTI supplied under A815?
Ferritic (S43000, S44600, S44627), duplex/super duplex (S31803, S32205, S32750, S32760, S32950, S39274, S32550, S32101, S32202), and martensitic (S41000, S41008, S41500).

Q4. What ASTM A815 dimensions and schedules are available in DIPTI METAL INDUSTRIES?
Standard dimensions to ASME B16.9 (WP) and MSS SP-43 (CR), sizes ½″ to 48″, schedules 5S through XXS (grade-dependent).

Q5. Dipti Metal Industries export ASTM A815 internationally?
Yes—regular shipments to the Middle East, Asia, Europe, Africa, the Americas, and Oceania with complete documentation and project packaging.
