304 Stainless Steel Plate: About & Fact

What makes a person differ from others? You might all say it’s a person’s thinking process, functioning, behaviour & other traits. Similarly, in industrial line, there’s huge difference between 304L, 304H & 304 Stainless Steel Plate.

Before jumping into this concern, there’s a lot to know about 304 Stainless Steel Plate that is indeed for you to understand to conclude what’s best for you & how can you use its properties to increase productivity & mark a standard.

Features & Specifications

Also known as Chromium-Nickel austenitic alloy, this material features favourable properties, such as corrosion oxidation resistance, high ductility, less carbide precipitation, excellent weldability, forming, spinning & drawing.

Nonetheless, it has excellent resistance to an extensive range of atmospheric conditions & corrosive media. It is resistance to crevice, pitting & stress corrosion cracking. It is subjected to surface treatment, like 2B, 2D, BA, NO.1, NO.4, NO.8, 8K, mirror, checkered, embossed, hair line, & sand blasting, to increase its mechanical properties, impact resistance & durability.

Types of 304 Stainless Steel Plate 

Although all possess same chromium-nickel content & same corrosion resistance, weldability & fabrication, the main difference between 304, 304L & 304H Stainless Steel Plate is the carbon content.

304H has 0.04–0.10% ((highest) carbon content, 304L has 0.03% (lowest) carbon content & 304 has 0.08% carbon content. The more the carbon content, the more it is susceptible to corrosive attack & rusting. Therefore, 304 is not useful for corrosive applications & thus 304L is preferred.  Higher carbon content stainless steel, like 304H, is useful for higher temperature & strength applications.

Vast Area of Applications

304 Stainless Steel Plate is extensively used in industrial & household applications such as food processing equipment, food handling equipment, refrigerators, tabletops, sinks, chemical containers, tanks, high-pressure vessels, machinery parts, automobile etc.
