We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.
Ordinary austenitic steels of the AISI 304 and AISI 316 varieties are prone to emphasize corrosion cracking in chloride-bearing solutions at temperatures above about 60°C (140oF). At high temperatures, above about 100oC, chloride contents as little as within the ppm-range (10-four %) are adequate to cause stress corrosion cracking in these steels. A nickel content material of 25%, as is the case for Sandvik 2RK65™, is adequate to supply excellent resistance underneath working situations. Ordinary austenitic steels of the ASTM 304 and ASTM 316 sorts are prone to stress corrosion cracking (SCC) in chloride-bearing options at temperatures above about 60°C (140oF). At excessive temperatures, above about 100oC (212°F), chloride contents as low as in the ppm-range (10-4 %) are sufficient to cause stress corrosion cracking in these steels.
The high chromium and molybdenum contents of this steel make it very proof against pitting. This has been verified by in depth sensible experience of service involving chloride-bearing course of solutions and seawater cooling.
A nickel content material of 25% is adequate to provide very good resistance under sensible conditions. Autoclave exams at totally different chloride contents and temperatures present useful knowledge for materials choice. Also this kind of testing demonstrates the nice SCC-resistance of Sandvik 2RK65™, far better than ASTM 304 and ASTM 316 types of steels, see Figure 10. Laboratory checks in calcium chloride confirm the prevalence of Sandvik 2RK65™ in resisting stress corrosion cracking in comparison with ASTM 304 and ASTM 316.
- A nickel content of 25%, as is the case for Sandvik 2RK65™, is adequate to supply very good resistance under working circumstances.
- At excessive temperatures, above about 100oC, chloride contents as low as in the ppm-vary (10-4 %) are enough to cause stress corrosion cracking in these steels.

Tests have demonstrated that the steel fulfils the requirements (60 J (forty four ft-lb) at -196 oC (-320 oF)) according to the European requirements EN (UFPV-2) and EN . For additional data concerning corrosion resistance of Sandvik 2RK65™, please see the info sheet – Seamless tube and pipe – Sandvik 2RK65™.
The grade can be characterised by excellent general corrosion resistance and good weldability. The machining of Sandvik 2RK65™, as with other stainless steels, requires an adjustment to, tooling knowledge and machining technique, in order to obtain passable results. Compared to Sanmac® 316/316L, the chopping velocity must be decreased by approximately 40-forty five%, when turning Sandvik 2RK65™ with coated, cemented carbide instruments.
The grade is an excellent different to plain austenitic stainless steels in heat exchangers utilizing high temperature water with chloride contamination. The good ductility of Sandvik 2RK65™ permits bending within the cold state to the smallest bending radii attainable with trendy methods and machines. Due to its austenitic microstructure, Sandvik 2RK65™ has very good influence power each at room temperature and at cryogenic temperatures.
bends are manufactured as normal in Sandvik 2RK65™ in accordance with ANSI B16.9 and, the place applicable, ASTM A403. Flanges are made as standard to ANSI B16.5 in the type of slip-on flanges (class 150) and weld neck flanges (class 300), and to relevant sections of ASTM A182. Fittings could be manufactured to different standards by settlement. Other types of fittings corresponding to reducers, tees and couplings may also be provided on request. Sandvik 2RK65™ is a multi-function materials for use under severe corrosion conditions.
