High strength UNS S31254/1.4547 stainless steel rod size specification Black rod low magnetization characteristics
Introduction to UNS S31254 Material:
UNS S31254 is a high-performance super austenitic stainless steel that exhibits exceptional adaptability under multiple extreme working conditions due to its outstanding corrosion resistance and mechanical strength. This material is mainly composed of chromium, nickel, molybdenum, as well as small amounts of nitrogen and copper elements, among which the high content of molybdenum (usually over 4%) is the key to its outstanding corrosion resistance.
UNS S31254 not only maintains excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride environments, but also exhibits good corrosion resistance in sulfuric acid, phosphoric acid, and various organic acids, making it widely used in various fields such as marine engineering, chemical equipment, pharmaceuticals, and food processing.
The main advantages of UNS S31254 include its excellent corrosion resistance, stress corrosion cracking resistance, seawater crevice corrosion resistance, good corrosion resistance, and super strong corrosion resistance in harsh environments such as high temperature seawater.
The chemical composition of UNS S31254 mainly includes nickel, chromium, molybdenum, copper, nitrogen, carbon, manganese, silicon, phosphorus, and sulfur.

The range of manganese content is 1.0%.
The range of silicon content is 0.8%.
The range of phosphorus content is 0.03%.
The range of sulfur content is 0.01%.
These chemical components endow UNS S31254 with excellent corrosion resistance, especially in marine environments and other harsh corrosive environments. In addition, it also has good resistance to chloride ion stress corrosion cracking and particle corrosion, as well as excellent resistance to point corrosion and crevice corrosion. Therefore, UNS S31254 is widely used in various applications that require high corrosion resistance.
This material can still maintain high strength and toughness at high temperatures, which is crucial for industrial equipment that needs to withstand high temperature and high pressure environments. In addition, its excellent processing performance and weldability make the material more adept at manufacturing complex structural components. In today's increasingly important environment, UNS S31254 has become one of the important materials for promoting green manufacturing and reducing environmental pollution due to its excellent corrosion resistance and recyclability.
The density of UNS S31254 is 8.0g/cm ³, and the melting point is 1320-1390 ℃. The corrosion resistance of this material is due to its special chemical composition ratio, which enables it to maintain good performance in many extreme and harsh environments, especially in harsh environments such as high temperature seawater, and also has super strong corrosion resistance.
