dc.description.abstract | Baja adalah material yang paling banyak di gunakan untuk keperluan industri logam dan mesin . Secara garis basar baja di bedakan manjadi : A. Baja karbon l. Baja karbon rendah ( <0,30 % C ) 2. Baja karbon sedang ( 0,30 % C - 0, 70 %C) 3. Baja karbon tinggi ( 0,70% C - 0,80 % C) B. Baja paduan 1. Baja paduan rendah ( jumlah paduan khusus < 8,0 % ) 2. baja paduan tinggi (jumlah paduan khusus > 8,0 % ) Dalam penggunaannya baja dapat digunakan langsung atau dengan memberi perlakuan khusus untuk merubah sifat sifat dari baja tersebut seperti proses hardening,tempering , annealing ( anil ),normalizing ,elektro plating dan lain ya. Dalam pembahasan kali ini adalah bagai tentang bagaimana pengaruh perlakuan panas terhadap sifat - sifat mekanis dari baja karbon sedang dan juga struktur mikro dari baja karbon sedang yaitu baja NS 1045.Baja NS 1045 adala baja standarisasi Jepang (NS =Nippon Standard ).Dimana anggka 10 disini adalah angka yang menandakan baja karbon menurut Intemasional sedangkan angka 45 adalah kadar C (karbon ) minimal.Dari hasil riset yang saya lakukan menunjukan bahwa perlakuan panas yaitu Hardening kemudian di tempering dapat meningkat kan kekerasan ,;..:euletan dan kekuatan tarik serta merubah struktur mikro menjadi lebih halus. Dengan demikian dapat disimpulkan bahwa perlakuan panas yang terkendali dapat merubah sifat - sifat mekanis dari baja tersebut tergantung dari jenis proses yang dilakukan sertajenis baja yang dipakai. Steel is a material which is many most used for metal industry and machine needed.marginaly steel is differentiated becoming: A. Carbon steel I .Low Carbon steel ( < 0,30 %C) 2. Medium Carbon steel ( 0,30%C -0,70 % C) 3. High Carbon steel ( 0,70 %C- 0,80 % C) B. Alloy Steel 1. Low alloy Steel (amount of special mixture< 8,0 % ) 2. High Alloy steel (amount of special mixture> 8,0 % ) In it use Steel can be used direct or by giving special treatment to changing characteristics that steel , like hardening , tempering , annealing ,normalizing, electro plating and other . This under Concideration is about how heat treatment influence into characteristics of a medium Carbon steel and also micro structure of medium carbon steel that is NS 1045 Steel . NS 1045 steel is Japan's standardization (NS= Nippon Standard), Where numbers I 0 here is a number which is designating of carbon steel the international according to , while number of 45 it is minimal rate of carbon ( C ) . From the research result which I have done indicate that heat treatment that is hardening lather than tempering can upgrade that hardnes ,tenacity,and tensile strength and also changing the micro structure becoming softer. There by can concluded that heat treatment which in control can changing a characteristics of that steel depended from a type of process which done and also a type of steel which is used. | en_US |
