What Is 1.4410 Material Equivalent To ASTM?

what is 1.4410 material ?

1.4410 (also known as UNS S32750, F53, or Alloy 2507) is a high-performance super duplex stainless steel designed to deliver exceptional strength and superior corrosion resistance, making it particularly suitable for demanding, chloride-rich environments. Featuring a balanced 50/50 austenite-ferrite microstructure, this material contains an approximate composition of 25% chromium, 4% molybdenum, and 7% nickel, and exhibits outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking.

 

What is 1.4410 material equivalent to ASTM?

The 1.4410 (X2CrNiMoN25-7-4) material is a super duplex stainless steel primarily equivalent to ASTM/UNS S32750. It is often referred to by the trade name SAF 2507 and, specifically for forgings, it aligns with ASTM A182 F53.

◎ a=air; o=oil; w=water. ◎ The temperatures of annealing should be agreed for simulated heat treated test pieces. ① Solution annealing in the range specified followed by sufficiently rapid cooling to avoid precipitation of deleterious phases is essential after hot forming these steets. ② If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded.

 

What is the difference between 1.4410 and 1.4462?

Both 1.4410 (UNS S32750, also known as 2507) and 1.4462 (UNS S31803/S32205, also known as 2205) are duplex stainless steels; however, 1.4410 is a higher-performance "super duplex" steel. The strength of 1.4410 is significantly higher than that of 1.4462, featuring a minimum yield strength of 550 MPa compared to 450 MPa for 1.4462. This makes 1.4410 suitable for applications involving higher pressures or for designs utilizing thinner wall thicknesses.

 

What is the difference between 1.4410 and 1.4401?

 1.4410 (UNS S32750, 2507) is a super duplex stainless steel, whereas 1.4401 (equivalent to 316) is an austenitic stainless steel; the two differ significantly in both structure and properties. Thanks to its duplex structure, 1.4410 possesses strength and hardness more than double that of 1.4401, with a yield strength of approximately 590 MPa, compared to about 230 MPa for 1.4401.

 

Is 1.4410 stainless steel magnetic?

Yes, 1.4410 stainless steel (also known as Super Duplex, Alloy 2507, or UNS S32750) is magnetic. As a duplex steel, it has a mixed microstructure of approximately 50% austenite and 50% ferrite, with the high amount of ferrite causing it to be magnetic and attracted to magnets.

 

1.4410 Super Duplex Stainless Steel price per kg

The price of 1.4410 (Super Duplex Stainless Steel UNS S32750/F53) typically ranges from $1.50 to $6.00 per kilogram, depending on the product form (plates, bars, tubes), order quantity, and prevailing market conditions. Prices for large-volume orders placed directly with steel mills may be lower, whereas prices for small-batch purchases or specific finished components such as flanges will be relatively higher.
