Corrosion Resistance of Stainless Steels

Corrosion resistance of stainless steels Corrosion in concrete (corrosion problems are not limited to outside surfaces !) Stainless steel provides both strength and corrosion resistance inside the concrete, providing a long, maintenance-free service life of the structure. Corrosion of unprotected carbon steel occurs even inside reinforcedCorrosion-resistant Casting Alloys - FlowserveGood resistance to chemical attack is a given requirement for corrosion-resistant castings. In general, the cast alloy must exhibit corrosion resistance comparable to the wrought product that it is complementing. To develop this corrosion resistance, the cast producer must understand the interaction between chemical composition, thermal history corrosion resistant steel grades qualitycastingsSTEEL CASTINGS HANDBOOK Supplement 7 Welding of differences make it desirable to consider the corrosion and heat groups separately. 2.1 Corrosion resistant grades Electrical resistivity of the corrosion resistant alloys is five to ten times higher than carbon steel. Welding current requirements therefore, are lower than for carbon steel

AUSTENITIC STAINLESS STEELS | QualityCastings

The basic 18% chromium/10% nickel grade (R31) has a very good corrosion resistance in many applications. This alloy can be refined (R31LC) or alloyed with molybdenum (R33,R34) for enhanced corrosion resistance or modified for improved welding (R30) and machining (R32) characteristics.About Quality Castings | QualityCastingsWith a background in high alloy steels, this same technology and standard of quality was applied across the complete range of irons and steels, including Ductile iron, Chrome iron, Ni-hard, low alloy steels, high strength steels, wear resisting steels, heat resisting steels and corrosion resistant stainless steels including duplex grades corrosion resistant steel grades qualitycastingsArticle: Duplex Stainless Steels - A Simplified GuideCorrosion Resistance of Duplex Steels . The range of duplex steels allows them to be matched for corrosion resistance with the austenitic and ferritic steel grades. There is no single measure of corrosion resistance. However, it is convenient to use the Pitting Resistance Equivalent Number (PREN) as a means of ranking the grades.
