254SMO Hot rolled stainless steel plate

‌254SMO stainless steel plate‌ is a high-performance super austenitic stainless steel with excellent resistance to pitting and crevice corrosion due to its high content of molybdenum (6.0-6.5%).
254SMO hot-rolled stainless steel plate has a density of 8.1g/cm³, a melting point of 1320℃, and a hardness range of 182-223HB‌. In addition, the material maintains stable performance in high temperature environments, with a maximum operating temperature of 538℃‌.

Q: What is the price of 254SMO? Is it better than Hastelloy?
Price range: about 2-3 times of 316L and 1.5 times of 904L;
Compared with Hastelloy: the price is only 1/3-1/2 of Hastelloy C-276, and the processability is better, which is suitable for replacing high-cost nickel-based alloys.
Q: How to verify the quality of 254SMO stainless steel plate?
Certification documents:
Provide ASTM A240/EN 10088-2 material certification and SGS test report;
NACE MR0175 sulfide stress cracking resistance certification and FDA food contact certification can be attached.
Testing methods:
Spectral analysis verifies composition, ultrasonic flaw detection detects internal defects, and salt spray test evaluates corrosion resistance.
