Quenching and partitioning (Q&P) treatment was applied to a commercial low carbon martensitic stainless steel, AISI Type 410 (Fe-12Cr-0.1C). The condition of partial quenching and partitioning was optimized with consideration of the untransformed austenite fraction and stability of austenite (carbon concentration in solid solution). As a result, the amount of retained austenite could be increased up to approximately 15 vol%. Tensile testing revealed that the specimens after Q&P heat treatment exhibited lower yield stress and larger work hardening rate compared with quench-and-tempered (Q&T) specimens under the same tensile strength level, resulting in a significantly better strength-ductility balance. It was confirmed that the TRIP effect had contributed to the mechanical property.

Suatu permukaan logam yang berinteraksi langsung dengan lingkungan korosif dengan adanya keadaan ketidakseragaman akan terjadi perbedaan potensial efektif lokal, sehubunan dengan itu makan akan terjadi korosi pada daerah yang lebih anodic daripada permukaan lain disebabkan oleh perlakuan yang dilakukan pada material tersebut, misalnya adalah proses heat treatment. Dalam penelitian ini obyek yang diteliti adalah baja tahan karat martensitic stainless steel AISI dengan kadar krom 17%, kadar karbon 0,20%, kadar nikel 1,6%. Pada penelitian kali ini akan dilakukan suatu penelitian terhadap pengaruh variasi temperatur pemanasan pada proses heat treatment terhadap laju korosi. Proses heat treatment disini adalah menggunakan temperatur pemanasan : 750ºC, 850ºC, 950ºC, ditahan 30 menit dan di quenching dengan media pendingin air. Dari proses heat treatment tersebut akan dilakukan pengujian kekerasan strukturmikro dan uji laju korosi, dimana metode yang digunakan adalah metode immerse (media korosif HCL). Dari hasil pengujian tersebut di atas didapatkan hasil sebagai berikut : baja tanpa laku panas mengalami laju korosi sebesar 51,8 mpy, untuk baja mengalami laku panas 750ºC dengan holding time 30 menit. Laju korosi specimen 1 adalah 50 mpy, specimen 2 adalah 30 mpy, specimen 3 adalah 76 mpy, specimen 4 adalah 68 mpy, specimen 5 adalah 67 mpy. Untuk laku panas 850ºC, laju korosi specimen 1 adalah 43 mpy, specimen 2 adalah 61 mpy, specimen 3 adalah 46 mpy, specimen 4 adalah 29 mpy, specimen 5 adalah 27 mpy. Untuk laku panas 950ºC, laju korosi specimen 1 adalah 82 mpy, specimen 2 adalah 84 mpy, specimen 3 adalah 78 mpy, specimen 4 adalah 75 mpy, specimen 5 adalah 77 mpy.

Abstract EASTERN STAINLESS Type 316L is a chromium-nickel-molybdenum steel with a very low carbon content (0.03 max.) Its general resistance to corrosion is similar to AISI Type 316 but, because of its low carbon content, it has superior resistance to the formation of harmful carbides that contribute to intergranular corrosion. Type 316L is used widely in many industries such as chemical, food, paper, textile, nuclear and oil. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-439.

Abstract AL TECH MIAMI is both a hardenable stainless steel (AISI Type 420) and a tool steel for making molds for plastic. A major requirement for plastic mold steel is corrosion resistance. Certain plastics, such as poly-vinyl chlorides, are very corrosive and stored molds often rust from sweating water lines and/or humid environments. AL TECH MIAMI has good resistance to wear. It is melted and AOD refined to assure the mold-maker of cleanliness and freedom from internal imperfections. It provides exceptionally good polishability for lens-quality molds. 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 machining. Filing Code: SS-435. Producer or source: AL Tech Specialty Steel Corporation.

Abstract EASTERN STAINLESS TYPE 304L is the basic 18-8 chromium-nickel austenitic stainless steel with a very low carbon content (0.03% max.). Its general resistance to corrosion is similar to AISI Type 304 but, because of its low carbon content, it has superior resistance to the formation of harmful carbides that indirectly contribute to intergranular corrosion. It is recommended for most articles of welded construction. Postweld annealing is not necessary. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SS-427.
