Stainless Steel Sheets 304 2b

Stainless steel sheets 304 2B refers to a specific type of stainless steel sheet made from grade 304 stainless steel and finished with a 2B (bright annealed) surface finish. Here's a breakdown of the terms:

 

Stainless Steel: Stainless steel is a corrosion-resistant alloy that contains iron, chromium, and often other elements such as nickel or molybdenum. It is widely used in various industries due to its durability and resistance to rust and staining.

 

Grade 304: Grade 304 is a common type of stainless steel and is often referred to as "18/8" stainless steel because it contains 18% chromium and 8% nickel. It is known for its excellent corrosion resistance, good formability, and versatility. Grade 304 is suitable for a wide range of applications, including kitchen equipment, food processing, and architectural uses.

 

2B Finish: The 2B finish is one of the most commonly used surface finishes for stainless steel sheets. It stands for "bright annealed" and provides a smooth, reflective surface with a low gloss. This finish is achieved by cold-rolling the stainless steel sheet, followed by annealing and descaling processes. The result is a clean, uniform surface without any visible grain or texture.

 

Stainless steel sheets with a 304 2B finish are sought after for applications where a visually appealing, corrosion-resistant surface is desired, such as in decorative elements, kitchen backsplashes, countertops, appliances, and automotive trim.

The chemical composition of 304 2B stainless steel is as follows:

Iron: The primary component, typically ranging from 65-75%.

Chromium: Provides corrosion resistance, usually present in a range of 17-20%.

Nickel: Enhances corrosion resistance and high-temperature properties, typically present in a range of 8-10.5%.

Manganese: Improves the mechanical properties of stainless steel, usually present around 2%.

Silicon: Contributes to the corrosion resistance and strength characteristics of stainless steel, typically present around 1%.

Phosphorus: Controls the cold working properties of stainless steel, typically present around 0.045%.

Sulfur: Improves the machinability of stainless steel, typically present around 0.03%.

Carbon: Increases the strength and hardness of stainless steel, typically present around 0.08%.

These percentages may vary slightly depending on the manufacturer and specific standards. It's always recommended to consult the manufacturer's datasheet for precise chemical composition information for a specific grade of stainless steel, including 304 2B.

Here are more professional and detailed specifications for 304 2B stainless steel sheets:

Thickness: Typically available in a range from 0.5mm to 3.0mm or thicker. More specific thickness options may include 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, and so on.

Width: Common width options include 1000mm, 1219mm (4 feet), 1500mm, and 2000mm. Other possible width specifications include 914mm, 1250mm, 1524mm, and so on.

Length: Typically offered in standard lengths such as 2000mm, 2438mm (8 feet), or 3048mm (10 feet). Other possible length specifications include 2500mm, 3000mm, and so on.

Surface Finish: 2B (bright annealed) refers to a stainless steel surface with a bright annealed treatment, resulting in a low-gloss, smooth, and non-directional surface without visible grain or texture.

Hardness: The typical hardness range for 304 stainless steel sheets is HB 90-200 (Brinell hardness) or HRB 46-92 (Rockwell hardness).

It's important to note that different suppliers and manufacturers may offer variations in specifications, so it's advisable to contact the specific supplier to obtain accurate information regarding available specifications and customization options. Additionally, customized specifications can be discussed and determined based on specific requirements.

Here are the mechanical properties typically associated with 304 2B stainless steel sheets:

Tensile Strength: The tensile strength of 304 stainless steel is typically in the range of 515 to 690 megapascals (MPa).

Yield Strength: The yield strength of 304 stainless steel is typically around 205 to 260 MPa.

Elongation: The elongation at break, which measures the ability of the material to stretch without fracturing, is typically around 40 to 60%.

Modulus of Elasticity: The modulus of elasticity, also known as Young's modulus, is approximately 193 gigapascals (GPa). It represents the material's stiffness and ability to withstand deformation under stress.

Hardness: The hardness of 304 stainless steel can vary depending on the heat treatment and specific grade. The typical hardness ranges from 70 to 90 HRB (Rockwell B hardness) or 85 to 150 HB (Brinell hardness).

It's important to note that these values are general ranges and can vary slightly depending on factors such as manufacturing processes, heat treatment, and specific product variations. For precise and up-to-date mechanical property information, it is recommended to consult the manufacturer's datasheet or contact the specific supplier.
