Stainless Steel 347 Pipe Fittings – Manufacturer, Supplier & Exporter | Mcneil Instruments India

Introduction

At Mcneil Instruments India, we specialize in the engineering, manufacturing, and global export of Stainless Steel 347 Pipe Fittings — precision-built components crafted to endure high temperatures, aggressive environments, and complex process conditions.
Designed for industries where thermal stability, corrosion resistance, and weld reliability are non-negotiable, our SS 347 and SS 347H fittings are trusted across refineries, petrochemical complexes, thermal plants, and power generation networks.

Each fitting — whether elbow, tee, reducer, bend, stub end, or end cap — is produced to ASTM A403 WP347 / WP347H, ASME B16.9, and ANSI/DIN standards. We engineer them with dimensional accuracy, smooth internal finish, and optimum strength-to-weight ratio, ensuring leak-free performance and mechanical endurance in every system.

What is Stainless Steel 347?

Stainless Steel 347 (UNS S34700 / Werkstoff Nr. 1.4550) is an austenitic chromium-nickel stainless steel stabilized with niobium (columbium) and tantalum to prevent carbide precipitation during welding and prolonged high-temperature exposure.
This stabilization makes SS 347 particularly suited for applications where materials like 304 or 316 might lose strength or suffer intergranular corrosion after thermal cycling.

For higher heat resistance, the 347H variant (UNS S34709) incorporates a higher carbon content (0.04–0.10%), which improves creep strength and stress-rupture resistance, making it ideal for continuous service above 900°C.

Stabilization Advantage

The niobium-tantalum combination forms stable carbides instead of chromium carbides, preserving chromium content in the matrix — which in turn maintains a protective passive film, ensuring corrosion protection even in sensitizing temperature ranges (450°C–850°C).

Understanding Stainless Steel 304L – Composition and Metallurgical Behavior

Stainless Steel 304L (UNS S30403 / Werkstoff 1.4306) is a low-carbon modification of the standard 304 stainless steel — the “L” indicating a maximum carbon content of 0.03%. This small adjustment dramatically enhances resistance to intergranular corrosion and sensitization during welding or high-temperature exposure.

Microstructure and Alloy Design

SS 304L is an austenitic chromium-nickel alloy, stabilized by a homogeneous microstructure that retains ductility and toughness across a broad temperature range. The alloy achieves its corrosion resistance through:

18–20% Chromium (Cr): Forms a passive oxide layer that resists oxidation and surface scaling.
8–12% Nickel (Ni): Improves toughness, formability, and pitting resistance.
Low Carbon (<0.03%): Prevents chromium carbide precipitation at grain boundaries.

This balance of chemistry makes 304L ideal for welded assemblies, pressure piping, and clean processing systems where long-term corrosion resistance and cleanliness are vital.

Detailed Chemical Composition

Element	Content (%)	Role / Benefit
Carbon (C)	≤ 0.03	Reduces carbide precipitation and improves weld corrosion resistance
Manganese (Mn)	≤ 2.00	Improves hot workability and strength
Silicon (Si)	≤ 1.00	Enhances oxidation resistance during high-temperature service
Chromium (Cr)	18.0 – 20.0	Provides corrosion and oxidation resistance
Nickel (Ni)	8.0 – 12.0	Enhances ductility, toughness, and chloride resistance
Phosphorus (P)	≤ 0.045	Controlled to prevent brittleness
Sulfur (S)	≤ 0.03	Improves machinability within limits
Iron (Fe)	Balance	Matrix metal providing structural strength

Mechanical & Physical Properties

Property	Metric Value	Significance
Tensile Strength	≥ 485 MPa	High load-bearing capacity
Yield Strength (0.2% Offset)	≥ 170 MPa	Resists deformation under stress
Elongation	≥ 35%	Ensures ductility and flexibility
Hardness (HRB)	≤ 90	Ideal for machining and forming
Modulus of Elasticity	193 GPa	High rigidity under mechanical stress
Density	8.00 g/cm³	Indicates structural mass
Thermal Conductivity	16.2 W/m·K	Maintains dimensional stability
Melting Range	1400–1450°C	Suitable for high-temperature use

The low carbon content allows SS 304L to be welded, cold-formed, or machined without compromising corrosion resistance — a crucial advantage over 304 in fabrication-heavy applications.

Corrosion & Heat Resistance

304L stainless steel performs exceptionally in oxidizing, mildly reducing, and slightly acidic environments.
It resists oxidation up to 870°C (1600°F) in intermittent service and up to 925°C (1700°F) in continuous service.

Resistance Profile

General Corrosion: Excellent resistance in atmospheric and freshwater environments.
Intergranular Corrosion: Superior immunity post-welding due to low carbon.
Pitting/Crevice Corrosion: Effective in chloride solutions below 200 ppm.
