O a\u00e7o inoxid\u00e1vel 17-4 PH (UNS S17400) \u00e9 um material \u00fanico e importante que se situa entre a resist\u00eancia \u00e0 corros\u00e3o dos graus austen\u00edticos comuns (como o 304) e a resist\u00eancia extrema dos a\u00e7os-ferramenta martens\u00edticos.<\/span><\/p>\n

Quando os engenheiros perguntam \u201cO que \u00e9 o 17-4 PH?\u201d, geralmente est\u00e3o tentando descobrir como obter alta resist\u00eancia sem perder a resist\u00eancia \u00e0 corros\u00e3o. O mais importante sobre esta liga \u00e9 que sua resist\u00eancia n\u00e3o vem do encruamento ou de muito carbono. No entanto, n\u00e3o \u00e9 um a\u00e7o inoxid\u00e1vel de Endurecimento por Precipita\u00e7\u00e3o (PH). Isso significa que suas propriedades mec\u00e2nicas, como limite de escoamento, dureza e ductilidade, podem ser alteradas por um processo controlado de tratamento t\u00e9rmico chamado envelhecimento.<\/span><\/p>\n

Essa ajustabilidade permite que os projetistas obtenham limites de escoamento de at\u00e9 1100 MPa (160 ksi), o que \u00e9 tr\u00eas vezes maior que o a\u00e7o inoxid\u00e1vel 304, mantendo ainda boa estabilidade dimensional. \u00c9 muito raro encontrar um material que tenha um bom equil\u00edbrio entre alta resist\u00eancia, resist\u00eancia \u00e0 corros\u00e3o moderada e fabricabilidade previs\u00edvel.<\/span><\/p>\n

Esse equil\u00edbrio \u00e9 o motivo pelo qual o 17-4 PH \u00e9 o padr\u00e3o para conex\u00f5es aeroespaciais, eixos de bombas qu\u00edmicas e conjuntos mec\u00e2nicos de alta carga. Os engenheiros podem usinar pe\u00e7as no estado mais macio de Solubiliza\u00e7\u00e3o (Condi\u00e7\u00e3o A) e depois trat\u00e1-las termicamente at\u00e9 a dureza final com pouca distor\u00e7\u00e3o. Mas n\u00e3o pode ser usado como substituto do 316 o tempo todo. Dependendo da condi\u00e7\u00e3o de tratamento t\u00e9rmico, sua tenacidade e resist\u00eancia \u00e0 corros\u00e3o podem ser muito diferentes. Este guia aborda a metalurgia, as realidades de processamento e os trade-offs de engenharia do 17-4 PH para ajud\u00e1-lo a determinar quando ele \u00e9 a melhor escolha.<\/span><\/p>\n

O que \u00e9 o a\u00e7o inoxid\u00e1vel 17-4 PH? Normas e Defini\u00e7\u00f5es para os Graus<\/span><\/h2>\n

17-4 PH significa que possui 17% de cromo, 4% de n\u00edquel e \u00e9 endurecido por precipita\u00e7\u00e3o. Do ponto de vista metal\u00fargico, \u00e9 um a\u00e7o inoxid\u00e1vel martens\u00edtico de endurecimento por precipita\u00e7\u00e3o.<\/span><\/p>\n

O 17-4 PH obt\u00e9m sua resist\u00eancia a partir de uma mudan\u00e7a de fase em duas etapas, enquanto os a\u00e7os da s\u00e9rie 300 obt\u00eam sua resist\u00eancia pelo endurecimento por solu\u00e7\u00e3o s\u00f3lida.<\/span><\/p>\n

        Para entender por que o 17-4 PH \u00e9 t\u00e3o vers\u00e1til, voc\u00ea precisa saber como ele endurece.<\/span><\/p>\n

                                Engineers can use 17-4 PH to make mechanisms that are lighter, stronger, and last longer by knowing how heat treatment affects performance.<\/span><\/p>\n

                                Perguntas frequentes<\/span><\/h2>\n

                                Q: Does 17-4 PH have a magnetic field?<\/span><\/strong>
                                A: Yes. It is ferromagnetic no matter how it is heat treated. If you need something that isn’t magnetic, don’t use it (use 316 or Nitronic 60 instead).<\/span><\/p>\n

                                Q: Does 17-4 PH rust?<\/span><\/strong>
                                A: It doesn’t rust easily in normal air and fresh water, just like 304. But it can pit and corrode in salt water or wet conditions that don’t move, especially in the H900 condition. It is best to passivate.<\/span><\/p>\n

                                Q: What’s the difference between 15-5 PH and 17-4 PH?<\/span><\/strong>
                                A: 15-5 PH is a cleaner, better version of 17-4 PH. It was made to be tougher across the grain and easier to forge. 17-4 PH is good enough for most general machined parts and is easier to find. 15-5 PH is often the best choice for important aerospace forgings.<\/span><\/p>\n

                                Q: After hardening, can I machine 17-4 PH?<\/span><\/strong>
                                A: Yes, but it’s hard. H900 (44 HRC) machining quickly wears out tools. It is common to machine in Condition A and then age, or to machine in H1150 (which is softer) if high strength isn’t needed.<\/span><\/p>\n

                                Q: Is 17-4 PH safe to eat?<\/span><\/strong>
                                A: Yes, most of the time. It is used in food processing machines for parts that have to deal with a lot of stress. But the surface finish must be smooth (electropolished) to stop bacteria from growing, and H1150 condition is best to keep stress corrosion cracking from happening during hot cleaning cycles.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"
