316L/316LN Stainless Steel Plate Custom Laser Cutting for Various Industries

316L and 316LN stainless steel plates are part of the austenitic family of stainless steels, which are well known for their excellent corrosion resistance, high strength, and formability. These grades are particularly suitable for demanding applications across various industries including chemical processing, marine environments, and food processing. The material is often used in both standard plate forms and custom laser-cut configurations to meet precise design requirements. This article provides detailed information on the technical properties, standards, and applications of 316L/316LN stainless steel plates, with a focus on their laser cutting capabilities for a range of industrial needs.

Product Overview

316L and 316LN are corrosion-resistant stainless steel alloys containing molybdenum (Mo), making them highly resistant to pitting and crevice corrosion in chloride environments. While 316L is the low-carbon version of 316 stainless steel, 316LN has the addition of nitrogen, improving the material’s strength and resistance to stress corrosion cracking, particularly in welded conditions.

These stainless steels are popular for applications where durability, strength, and resistance to corrosive environments are critical. The ability to perform precision laser cutting makes them ideal for a wide range of industries where exact dimensions and high-quality finishes are necessary.

Technical Parameters and Specifications

The following table outlines the key specifications and mechanical properties for 316L and 316LN stainless steel plates:

Notes:

• 316L has lower carbon content, reducing the risk of carbide precipitation during welding, which is particularly important for ensuring corrosion resistance.

• 316LN is similar to 316L but with nitrogen addition, enhancing the material’s strength, especially in welded sections.

Industry Standards

Both 316L and 316LN stainless steels are manufactured according to the following international standards:

• ASTM A240 – Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications.

• ASTM A480 – Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip.

• ISO 15510 – Stainless steels — Part 1: List of stainless steels.

• EN 10088-2 – Stainless steels — Part 2: Technical delivery conditions for sheet/plate and strip of corrosion-resistant stainless steels for general purposes.

These standards ensure that the stainless steel plates meet rigorous requirements for material properties, surface finish, and dimensional tolerances.

Key Features of 316L/316LN Stainless Steel Plate

• Corrosion Resistance: Both 316L and 316LN offer superior resistance to chloride-induced corrosion compared to other stainless steel grades like 304 or 304L. The addition of molybdenum significantly enhances pitting and crevice corrosion resistance, making these grades ideal for use in marine environments, chemical plants, and high-saline atmospheres.

• High Temperature Resistance: 316L and 316LN stainless steels retain their structural integrity at higher temperatures, making them ideal for applications involving heat exchangers and industrial machinery.

• Weldability: With low carbon content in 316L and the nitrogen-enhanced properties of 316LN, both materials are highly suitable for welding without significant loss of corrosion resistance. Welding can be performed using all common methods such as MIG, TIG, and stick welding.

• Formability: These steels are highly formable, which makes them suitable for laser cutting, stamping, and deep drawing operations. They are particularly well-suited for intricate, tight-tolerance components.

• Mechanical Properties: The increased nitrogen content in 316LN improves its tensile and yield strengths, making it a more robust material for applications under stress or high-load conditions.

Applications of 316L and 316LN Stainless Steel Plate

316L and 316LN stainless steel plates are widely used across various sectors, including:

1. Chemical Processing Industry: Resistant to aggressive chemicals and high temperatures, making them ideal for tanks, piping, and reactors used in chemical plants.

2. Marine and Offshore Applications: Due to excellent resistance to seawater and marine environments, these alloys are frequently used in boat hulls, offshore platforms, and marine engineering structures.

3. Food and Beverage Processing: Stainless steel's hygiene properties and resistance to acids and alkalis make it suitable for food processing equipment, including dairy processing and beverage production.

4. Pharmaceutical and Medical Devices: The corrosion resistance and non-reactivity of 316L and 316LN make them ideal for surgical instruments, implants, and other medical devices.

5. Architecture and Construction: For aesthetic purposes and long-term durability, these steels are often used in the construction of facades, railings, and decorative elements exposed to harsh weather conditions.

6. Power Generation: Components such as heat exchangers, reactors, and pressure vessels in the power generation industry benefit from the high heat resistance and durability of 316L/316LN.

Other Stainless Steel Products

In addition to stainless steel plates, many other forms and products can be produced from 316L and 316LN stainless steel, including:

• Stainless Steel Sheets – Thin, flat sheets used in applications requiring high corrosion resistance and aesthetic appeal.
