Chemical and Pharmaceutical - Dnya Stainless Steel

When choosing materials for chemical and pharmaceutical equipment, the primary considerations are corrosion resistance, purity, strength, and ease of cleaning. Here’s how stainless steel, duplex stainless steel, nickel alloys, and titanium plates compare for these applications:

1. Stainless Steel Plate

• Properties: Stainless steel is widely used in chemical and pharmaceutical industries due to its excellent corrosion resistance and ease of cleaning. It’s also durable and maintains its strength at various temperatures.
• Grades: For these applications, grades like 304 and 316 are commonly used. Type 316 stainless steel is preferred due to its superior resistance to chloride and other corrosive substances.
• Applications: Used in tanks, reactors, pipelines, and other equipment that handle chemicals and pharmaceuticals. The smooth surface finish helps prevent contamination and facilitates cleaning and sterilization processes.

2. Duplex Stainless Plate

• Properties: Duplex stainless steels offer high strength and excellent corrosion resistance, particularly against chlorides and other aggressive chemicals. They also provide better resistance to stress corrosion cracking than standard stainless steels.
• Grades: Common grades include UNS S32205 and UNS S32750.
• Applications: Suitable for applications that experience high pressure or aggressive chemical environments. Often used in heat exchangers, pressure vessels, and other equipment exposed to harsh conditions.

3. Nickel Alloy Plate

• Properties: Nickel alloys are known for their superior resistance to a wide range of chemicals, including strong acids and alkalis. They also perform well in high-temperature environments.
• Alloys: Examples include Inconel (nickel-chromium) and Monel (nickel-copper) alloys. For highly corrosive environments, Inconel 625 or Monel 400 are often used.
• Applications: Ideal for equipment that handles highly corrosive substances or operates at high temperatures. Examples include reactors, piping, and equipment used in chemical processing and pharmaceutical production.

4. Titanium Plate

• Properties: Titanium offers outstanding resistance to corrosion, even in highly acidic or alkaline environments. It is also lightweight and strong.
• Applications: Used in high-end applications where exceptional corrosion resistance and strength are required. Suitable for equipment like reactors, heat exchangers, and other components in aggressive chemical or pharmaceutical environments.

Summary

• Stainless Steel Plate (especially 316) is a common choice due to its balance of corrosion resistance, ease of cleaning, and cost-effectiveness. It’s suitable for most chemical and pharmaceutical equipment.
• Duplex Stainless Plate is ideal for high-strength applications and environments with aggressive chemicals, providing better resistance to stress corrosion and higher pressures.
• Nickel Alloy Plate excels in extremely corrosive environments and high temperatures, though it is generally more expensive and used for more specialized applications.
• Titanium Plate is used for highly corrosive and demanding applications where maximum corrosion resistance and strength are crucial, though it is one of the more costly options.

Selecting the right material depends on the specific chemical environment, temperature conditions, and mechanical requirements of the equipment.
