Briefing

S45000 martensitic age-hardenable stainless steel which exhibits very good corrosion resistance with strength.

Detailed

1.4594, XM-25, S45000, Stainless Steel

Alloy C450,XM-25 martensitic age-hardenable stainless steel which exhibits very good corrosion resistance with strength. X-25 alloy has a yield strength somewhat greater than 689 MPa in the annealed condition. A single-step aging treatment develops higher strength with good ductility and toughness.This stainless can be machined hot-worked and cold-formed in the same manner as other martensitic age-hardenable stainless steels. A particular advantage is ease of welding and brazing. XN-25 stainless is generally supplied in the annealed condition, requiring no heat treatment by the user for many applications. Mechanical properties will depend on the aging temperature selected.

Heat Treatment

Material shall be heat treated as follows:

- Hot rolled; overaged 1150°F ± 25°F, and prepared with no defects detrimental to forging/extruding.

- Solution treated, 1900°F ± 25°F, or water quench and prepared with no defects detrimental to forging/extruding.

- Solution treated, 1900°F ± 25°F, forced air cool or water quench and aged at 1070°F ± 10°F.

Hot Working

XM-25, S45000, 450 Alloy stainless steel alloy can be hot worked by soaking at 1150-1177°C (2100-2150°F) followed by cooling and fully annealing.

Cold Working

XM-25, S45000, 450 Alloy stainless steel alloy can be cold worked using all common techniques.

Annealing

XM-25, S45000, 450 Alloy stainless steel alloy is annealed by soaking at 1024-1052°C (1875-7925°F) for 1 h followed by quenching in water or oil.

Aging

XM-25, S45000, 450 Alloy stainless steel alloy is soaked at specific temperature for 4 h followed by cooling to obtain condition H900, H950, H1000, H1050 or H1150.

Welding Properties

XM-25, S45000, 450 Alloy stainless steel alloy can be welded using shielded methods to reduce contamination. Custom 450 solderability - Soldering and Brazing: No preheating is required to prevent cracking during soldering. Standard methods of welding stainless steel can be used with Custom 450. When optimum corrosion resistance is required, parts should be annealed after welding. A similar (Cmstom 450) filler material should be used to maintain optimum weld metal strength. The recommended brazing temperature should be consistent with the annealing temperature range so that re-annealing is not necessary. Brazing consumables used for Type 304 stainless steel shall be used.

Machining Properties

XM-25, S45000, 450 Alloy stainless steel alloy uses feeds and speeds comparable with other martensitic stainless steels. It is preferred to use positive feeds and slow speeds to achieve good results.Custom 450 Machinability: This alloy can be successfully machined by the same process as other martensitic stainless steels of comparable strength classes.thermal processing - this alloy is easy to thermal process in the temperature range of 900 ℃ ~ 1260 ℃. It is not only easy to process, but also to obtain fine grain size (this alloy). The optimum thermal processing temperature range is 1150 ° C ~ 1177 ° C. Cold working - Custom450 has a low work hardening rate and can be subjected to a large amount of cold working without intermediate annealing. Sharply bent deep drawing or stretching operations that produce localized elongations are to be avoided.
