304L stainless steel, also known as ultra-low carbon stainless steel, is a general-purpose stainless steel material widely used in the production of equipment and parts that require good overall performance (corrosion resistance and formability).
304L stainless steel is a general stainless steel material.
304L stainless steel grade:
The old standard JB/T 4237-1992 corresponds to 00Cr19Ni10
The new standard GB/T 20878-2007 stainless steel and heat-resistant steel grades and chemical composition
And GB 24511 2009 Stainless steel strip and strip for pressure equipment
The above corresponds to 022Cr19Ni10, containing about 0.03% carbon
Uniform Numeric Code S30403 is different from S30408 of 304
This is the most cost-effective steel grade. Therefore, the price of a 304L stainless steel strip is generally lower than other grades of stainless steel and all metal products. The material is available in different versions with low carbon and high carbon content. Low carbon versions of 304L strip are well suited for welding applications as they have less carbide precipitation and less localized corrosion.
304L stainless steel strip is the most common steel. 304L stainless steel strips have high corrosion resistance and are widely used in many appliances because they can be formed into any desired shape. We supply these stainless steel strips to various industries including chemical, electrical, food processing, pharmaceutical, petrochemical, and cement and gas industries. The 304L stainless steel belt has accumulated dust containing other metal elements or foreign metal particle attachments. In humid air, condensation between the deposit and the stainless steel plate connects the two to form tiny batteries, triggering electrochemistry. As a result, the protective film is damaged, which is called electrochemical corrosion.
