What is Incoloy material?

Incoloy is a registered trademark of Special Metals Incorporated and is applied to a family of nickel-based alloys primarily alloyed with chromium. There are more than ten different grades currently named within the Incoloy family, but the two most widely used Incoloy grades are Incoloy 825 and Incoloy 925. The high nickel content ensures resistance […]

What is Inconel good for?

Inconel grades are nickel-based alloys, primarily alloyed with chromium where Inconel is a registered trademark of Special Metals Incorporated. There are up to twenty different grades within the Inconel family, but Inconel 718 and Inconel 625 are perhaps the most widely known and used. Inconel alloys find use in numerous applications described below. Aerospace Industry: […]

What is the difference between Nitronic 50 and Nitronic 60?

Nitronic 50 and Nitronic 60 are both austenitic stainless steels but provide very different levels of mechanical and physical properties. Nitronic is a trademark of AK Steel Corporation and is applied to a range of stainless steel grades that utilised nitrogen as an alloying element. Nitronic 50 (Nit50, UNS S20910, DIN 1.3964, ASTM A182 XM19) […]

Is Nitronic 50 better than SS316?

Nitronic 50 provides both higher strength and improved corrosion resistance when compared with SS316, so would be considered a better product. However, due to its higher alloy content it is more expensive, and availability is lower in product forms other than solid round bar. Nitronic 50 (Nit50, UNS S20910, DIN 1.3964, ASTM A182 XM19) is […]

What material is 1.4460 equivalent to?

1.4460 (DIN 1.4460) is a super duplex stainless steel based upon 25% chromium content, also specified as UNS S32900, AISI 329 and EN X3CrNiMoN27-5-2. ‘Duplex’ stainless steels are a family of stainless steels that contain a mixed microstructure of austenite and ferrite phases. They offer a combination of good corrosion resistance and high strength, making […]

What is the equivalent of 1.4462?

DIN 1.4462 is a duplex stainless steel based upon a 22% chromium content. It can also be referred to as UNS S31803 (ASTM A182 F51) or UNS S32205 (ASTM A182 F60) when supplied as solid bar. The grade known as DIN 1.4462 was originally developed in the 1930s for application in paper and pulp manufacture. […]

Super Duplex

What is the difference between UNS S31803 and SS316?

UNS S31803 is a duplex stainless steel based upon a 22% chromium content, whereas SS316 is an austenitic stainless steel based upon an 18% chromium content. They have significantly different physical and tensile properties due to their different composition and microstructure. S31803 has better corrosion resistance and higher strength, but SS316 may be used for […]

What is UNS S31803 material?

UNS S31803 is a duplex stainless steel based upon a 22% chromium content. It is also identified at DIN 1.4462 and ASTM A182 F51. Developed in the 1930s for application in paper and pulp manufacture, it provided twice the strength and provide a significant uplift in corrosion resistance compared to the more general 304/316 stainless […]

Super Duplex

What is the equivalent of S31803?

S31803 is a duplex stainless steel based on a chromium content of 22% and can also be referenced as DIN 1.4462 and ASTM A182 F51 when supplied as round bar. Developed in the 1930s for application in paper and pulp manufacture, it provided twice the strength and a significant uplift in corrosion resistance compared to […]

Super Duplex

Is S31803 the same as S32205?

S31803 is almost identical to S32205 in terms of both composition, physical and tensile properties. S32205 is achieved by producing S31803 with certain elements – chromium, nickel and molybdenum, controlled to the upper limit of their range. As these three elements account for the resistance to pitting corrosion S32205 has a slightly improved and more […]

What is the disadvantage of duplex stainless steel?

Duplex stainless steels have many attractive properties, with their high strength and excellent corrosion resistance achieved in a cost-effective way. As such, they have become widely used in a wide variety of applications. However, there are instances where their characteristics are not best suited and other grades may have to be used. ‘Duplex’ stainless steels […]
