Alloy 725 is a nickel-chromium alloy with important additions of molybdenum, niobium and titanium, supplied within the scorching worked, annealed and age-hardened condition. It is age-hardened to achieve extremely excessive energy, roughly twice that of alloy 625 within the annealed condition. Alloy 718 is a high-energy, corrosion-resistant nickel chromium alloy supplied within the hot worked, answer annealed and age hardened situation. The addition of Nb, Ti, Al and Ni form a sequence of precipitates through the controlled solution annealing and ageing process steps, leading to a big increase in power and hardness. Alloy 625 is a nickel-chromium-molybdenum-niobium alloy , provided in the hot labored and annealed situation.

Controlled cold working ensures that the product achieves significantly elevated yield strengths over the annealed product, while retaining good ductility and toughness. Alloy four hundred is a nickel-copper (Monel® is Special Metals Corporation’s trademark for a household of Nickel-Copper alloys) single-part alloy most commonly supplied in hot worked and annealed situation. In its commonplace annealed condition it’s easy to type and fabricate with no requirements for additional heat therapies to re-steadiness the alloy. For occasion, the PREN for a duplex chrome steel (Sanmac 2205, SAF2205, 1.4462, F51/F60, S31803, S32205) is 34, whilst that for Alloy 316L (1.4404, S31603) is just 25.
A member of our team will be more than pleased to assist and can even advise you on the most suitable choice on your application. Ferralium® 255 weld wire is produced to complement our main tremendous duplex chrome steel. Ferralium® 255 – 3SC is a super duplex stainless-steel equipped in cast form. Hiduron® 191 is a medium-power precipitation hardened cupronickel alloy equipped within the hot labored situation.
Super duplex stainless steel contains a mix of austenitic and ferritic grains inside its microstructure. Austenitic microstructures are non-magnetic, but ferritic microstructures are. Alloy 825 HS110 is a excessive power nickel-iron-chromium alloy with additions of molybdenum, copper and titanium . We provide the metallic within the hot labored, annealed and chilly labored condition.
- 2507 is a brilliant duplex chrome steel designed for applications which require distinctive power and corrosion resistance.

How is duplex stainless made?
Duplex stainless steel. Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. When duplex stainless steel is melted it solidifies from the liquid phase to a completely ferritic structure.
It is optimised for fastener purposes, matching the mechanical properties of the B7 grade alloy carbon steel which is mostly used for prime-pressure bolting purposes. Ferralium® 255 – SD50 is a stainless steel which is equipped in the sizzling worked and annealed situation. It achieves higher strengths than most other stainless steels and alternative corrosion resistant alloys, offering the potential to reduce part size and due to this fact weight and value. As with all corrosion-resistant alloys, duplex stainless steels can suffer corrosion when uncovered to suitably corrosive conditions.
We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
