- Versatility: Available in various sizes and specifications to meet diverse application needs.
Standards and Specifications:
- ASTM A312: Standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes intended for high-temperature and general corrosive service.
Summary:
ASTM round stainless steel pipes made from grades 321, 904L, and 201 are versatile and reliable materials for various industrial and commercial applications. Each grade offers unique properties, making them suitable for specific environments and purposes. Grade 321 is ideal for high-temperature applications, 904L for aggressive corrosive environments, and 201 for cost-effective solutions in less demanding conditions. Their excellent corrosion resistance, mechanical properties, and versatility make them a preferred choice in many industries.
