Frequently Asked Questions (FAQs)
What are the key applications of 317 stainless steel in Chinese factories?
?
In Chinese factories, 317 stainless steel is widely used in various industries due to its excellent corrosion resistance and high strength. You can find it in chemical and petrochemical processing, food and beverage industries, petroleum refining, and even in the production of condensers for generator equipment and paper industry applications. Its ability to resist pitting and crevice corrosion makes it ideal for environments with high exposure to acids and chlorides.
How does 317 stainless steel compare to 316 stainless steel in terms of corrosion resistance?
?
317 stainless steel generally offers better corrosion resistance than 316 stainless steel, particularly against pitting and crevice corrosion. This is due to its higher molybdenum content, which enhances its resistance to corrosive environments such as those containing chlorides, bromides, and iodides. While both types are resistant to general corrosion, 317 stainless steel has a slight edge in more aggressive environments.
What are the advantages of using 317L stainless steel over 317 stainless steel?
?
When choosing between 317 and 317L stainless steel, you should consider the lower carbon content of 317L. This lower carbon content improves the welding performance and intergranular corrosion resistance of 317L, especially at high temperatures. This makes 317L a better option for applications where welding is critical and high-temperature resistance is required.
What standards and certifications do Chinese factories follow for 317 stainless steel production?
?
Chinese factories producing 317 stainless steel adhere to various international standards and certifications. These include ASTM A312, ASTM A213, EN10216-5, EN10217-7, DIN 17456, and JIS G3459, among others. Ensuring compliance with these standards guarantees the quality and reliability of the 317 stainless steel products.
How can you ensure the quality of 317 stainless steel products from Chinese factories?
?
To ensure the quality of 317 stainless steel products from Chinese factories, look for manufacturers that conduct 100% testing before shipment and offer third-party inspection options. Additionally, check if they provide mill certificates to EN10204 and other relevant test reports. Reputable manufacturers also allow for factory audits and maintain ISO-approved production processes.
