Abstract Allegheny Stainless Type 205 is a chromium-manganese nitrogen austenitic high strength stainless steel that maintains its low magnetic permeability even after large amounts of cold working. Annealed Type 205 has higher mechanical properties than any of the conventional austenitic steels-and for any given strength level, the ductility of Type 205 is comparable to that of Type 301. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as heat treating, machining, and joining. Filing Code: SS-640. Producer or source: Allegheny Ludlum Corporation.

Abstract AK Steel Type 304L is a chromium-nickel austenitic stainless steel. It is an extra low-carbon variation of Type 304 with a 0.030% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the “as-welded” condition, even in severe corrosive conditions. In many cases it eliminates the necessity of annealing weldments except for applications specifying stress relief. Type 304L has slightly lower mechanical properties than Type 304. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on high temperature performance, corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1324. Producer or Source: AK Steel Corporation.

Abstract UGIMA 4404 (UGIMA 316L) is identical to UGINE 4404 (AISI 316L) in analysis, corrosion resistance, mechanical properties, and forging and welding ability, but not with respect to machinability. A specific melting process creates inclusions of malleable oxides with a low melting point. The inclusions improve machinability by 20-30% compared with AISI 316L (1.4404) stainless steel. This datasheet provides information on composition and physical properties. It also includes information on corrosion resistance as well as heat treating, machining, and joining. Filing Code: SS-735.

Pit Initiation

The effects of C-substitution for part of the N content, on the pitting corrosion resistance and repassivation tendencies of duplex stainless steels (DSSs) were investigated. For this investigation, normal UNS S32205 containing N only (DSS-N) and the C-substituted DSS (DSS-NC) were fabricated. Microstructural analyses confirmed that the two DSSs had dual-phase microstructures without precipitates, and they possessed similar initial microstructure, including their grain sizes and phase fractions. Polarization and immersion tests performed in concentrated chloride solutions revealed that the DSS-NC was more resistant against stable pitting corrosion and possessed a higher repassivation tendency than the DSS-N. Furthermore, the corrosion pits initiated and propagated to a less corrosion resistant α phase. Polarization tests and corrosion depth measurements conducted in an HCl solution indicated that the DSS-NC exhibited lower galvanic corrosion rate between the α and γ phases than the DSS-N. Therefore, the growth rate of pit embryo was lowered in the DSS-NC, which shifted the potentials for the stable pit initiation and the pit extinction to the higher values.

Abstract ATI 201 HP is a 200-series, Cr-Mn-Ni austenitic stainless steel. It is comparable to the Cr-Ni stainless steel types 301, 304, and 304L in many respects, and can even provide some advantages over the 18-8 grades in certain applications. Because it possess a very desirable combination of economy plus good mechanical properties and corrosion resistance, it has been used in a wide variety of consumer and transportation applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-1332. Producer or source: ATI.
