Product Knowledge of 304L Stainless Steel Plate

Q1: What is the core difference between 304L and 304 stainless steel plates?

A1: The core difference is the carbon content: 304L has a carbon content of ≤0.03%, while 304 has a carbon content of ≤0.08%. 304L has no intergranular corrosion after welding, which is suitable for projects requiring large-area welding, while 304 may have intergranular corrosion.

Q2: What are the common thickness and size of 304L stainless steel plate for foreign trade?

A2: The common thickness is 0.5mm-20mm, and the common size is 1219×2438mm, 1500×3000mm. For thick plates (≥10mm), the size can be customized, and the maximum thickness can reach 50mm according to customer needs.

Q3: Can 304L stainless steel plate be used in chemical equipment?

A3: Yes, it is suitable for manufacturing chemical reaction vessels, pipelines and other equipment. It can resist corrosion from most neutral and weak acid-base media, and has stable performance in low-temperature and high-pressure environments, which meets the requirements of chemical industry standards.

Q4: What is the tensile strength of 304L stainless steel plate?

A4: Its tensile strength is 480-620MPa, yield strength is ≥170MPa, and elongation is ≥40%. It has good mechanical properties, which can withstand a certain load and is not easy to deform, suitable for structural parts and equipment manufacturing.

Q5: How to distinguish 304L and 304 stainless steel plates in foreign trade orders?

A5: The simplest way is to check the material certificate (MTC), which clearly marks the carbon content and material grade. In addition, professional testing methods such as spectral analysis can be used to detect the element content for accurate distinction.
