Sekilas tentang Monel 400 Paduan

Monel 400 adalah paduan nikel-tembaga larutan padat yang mengandung kira-kira 67% nikel dan 30% tembaga, along with small amounts of iron, mangan, dan silikon. This unique combination gives it exceptional resistance to a broad range of corrosive environments, termasuk asam fluorida, air laut, dan media basa.

Komposisi Kimia (%):

• Nikel (Di dalam): 63.0 – 70.0

• Tembaga (Cu): 28.0 – 34.0

• Besi (Fe): ≤ 2.5

• mangan (M N): ≤ 2.0

• Silikon (Dan): ≤ 0.5

• Karbon (C): ≤ 0.3

Key Features of Monel 400 Paduan:

• High corrosion resistance in seawater and brine environments

• Excellent resistance to hydrofluoric and sulfuric acids

• Maintains mechanical properties from cryogenic temperatures up to 550°C (1020°F)

• Non-magnetic and highly ductile

• Resistant to cavitation and pitting

Pada SASA MEMPANJANG, Monel 400 is manufactured and processed under strict metallurgical control to ensure superior performance and compliance with international standards such as ASTM B366, ASTM B165, and ASME SB366.

Ketahanan Korosi Monel 400

Monel 400 exhibits exceptional corrosion resistance in a wide range of environments, far beyond what most other metals can handle.

1. Resistance in Seawater and Marine Atmospheres

• Performs exceptionally in both freshwater and saltwater, even at high flow rates.

• Immune to mengadu, korosi celah, dan retak korosi tegangan caused by chlorides.

• Widely used for seawater piping, condenser tubes, and marine pump fittings.

2. Resistance to Acids and Alkalis

• Resistensi yang luar biasa terhadap asam fluorida (HF) in all concentrations up to boiling point.

• Excellent performance in asam sulfat dan klorida under controlled conditions.

• Resists alkaline corrosion, making it suitable for caustic soda (NaOH) lingkungan.

3. Resistance to Industrial Chemicals and Gases

• Tahan terhadap amonia, hydrogen fluoride, and sulfur gases.

• Performs well in chemical plants handling acids and salts.

• Maintains its structure and strength even under long-term exposure to corrosive fluids.

These corrosion-resistant properties make SASAFLANGE Monel 400 Perlengkapan Pipa ideal for long-term service in oil refineries, pabrik desalinasi, and chemical process systems.

Fabrication and Machinability

Although Monel 400 is stronger and harder than pure nickel, it remains highly workable and formable.

Fabrication Advantages:

• Easily hot- or cold-worked into complex shapes.

• Compatible with welding methods such as TIG, AKU, and shielded metal arc welding.

• Readily machined using carbide or high-speed steel tools.

• Can be annealed to restore ductility after forming or welding.

SASA MEMPANJANG employs advanced CNC machining and forging techniques to manufacture pipe fittings with precise tolerances and smooth internal surfaces, minimizing turbulence and flow resistance in critical fluid systems.
