Résumé / Abstract
The aim of this study was to analyze effectively the grinding power spent during the process and the surface roughness of the ground workpiece in the external cylindrical grinding of hardened SCM440 steel using the response surface method. A Hall effect sensor was used for measuring the grinding power of the spindle driving motor.
The surface roughness was also measured and evaluated according to the change of the grinding conditions. Response surface models were developed to predict the grinding power and the surface roughness using the experimental results. From adding simply material removal rate to the contour plot of these mathematical models,
it was seen that useful grinding conditions for industrial application could be easily determined.

A combined instrument for ultra-microhardness testing and atomic force microscopy (AFM) has been developed. The instrument could be employed to conduct hardness tests with a diamond indenter and its Si tip allowed high-resolution AFM images to be obtained at the same position on the specimen.
Ultra-microhardness tests and AFM observations were carried out on electrolytically polished specimens of a tungsten single crystal and JIS-SCM415 and JIS-SCM440 low-alloy steels. The SCM415 and 440 steels were tempered at 873K and 723K, respectively. The benefits of using a Si tip instead of
a diamond indenter for AFM observation are clearly shown by the better profile of the indent mark on the tungsten single crystal and the clearly distinguishable images of the fine carbides of the steels. The ultra-microhardness of the steels was influenced by the local microstructures such as the carbide density and the presence of a ferritic phase.

Fatigue tests of SCM 440 chromium molybdenum steel were carried out under high mean stress. Prediction method of fatigue strength based on fracture mechanics was developed and the following conclusions reached. (1) It has been shown that the ΔK_ becomes constant value at strain ratio R_ε > 0.5,
just as the fatigue limit becomes constant at R_ε> 0.5 .(2) It has been shown that the fatigue diagram could make without fatigue tests, if the range of stress intensity factor ΔK of intrinsic crack was compared with ΔK_ in various mean stress. (3) The prediction fatigue limit is in good agreement with the experimental value under high mean stress.

Abstract
Plasma nitrocarburizing and plasma oxidizing treatments were performed to improve the wear and corrosion resistance of AISI 4140 steel. Plasma nitrocarburizing was conducted for 3 h at 570 °C in the nitrogen, hydrogen and methane atmosphere to produce the var epsilon-Fe2–3 (N, C) phase.
It was found that the compound layer produced by plasma nitrocarburising was predominantly composed of var epsilon-phase, with a small proportion of γ'-Fe4 (N, C) phase.
The thickness of the compound layer was about 10 μm and the diffusion layer was about 300 μm in thickness, respectively. Plasma post oxidation was performed on the nitrocarburized samples with various oxygen/hydrogen ratio at a constant temperature of 500 °C for 1 h.
The very thin magnetite (Fe3O4) layer 1–2 μm in thickness on top of the compound layer was obtained by plasma post oxidation.
It was confirmed that the corrosion characteristics of the nitrocarburized compound layer can be further improved by the application of the superficial magnetite layer.
Key words: plasma nitrocarburizing; post oxidation; var epsilon-Fe2–3(N, C); γ'-Fe4(N, C); Fe3O4

Hot Rolled Coil/Plate

Detail Spesifikasi dan Dimensi (PDF)

Baja lembaran panas yang berupa coil dan pelat adalah jenis produk baja yang dihasilkan dari proses pengerolan panas. Pabrikan dan para pengguna jenis baja ini umumnya menyebut produk ini 'baja hitam' sebagai pembeda terhadap produk baja lembaran dingin yang juga biasa dikenal sebagai 'baja putih'.
Krakatau Steel juga memproduksi baja plain carbon dan baja micro-alloyed yang dapat digunakan untuk berbagai penggunaan, dari kualitas umum atau komersial hingga kualitas khusus, seperti struktur rangka baja, komponen dan rangka kendaraan bermotor, tiang pancang, komponen alat berat, fabrikasi umum, pipa dan tabung umum, pipa dan tabung untuk jalur pipa dan casing, tabung gas, baja tahan korosi cuaca, bejana bertekanan, boilers, dan konstruksi kapal. Hot Rolled Coil

Ketebalan pelat baja lembaran panas berkisar antara 0,18 hingga 25 mm, sedangkan lebarnya antara 600 hingga 2060 mm. Produk baja lembaran panas dapat diberikan dalam bentuk coil dan pelat. Kondisinya dapat berupa gulungan atau sebagai produk yang melalui proses pickling dan oiling (hot rolled coil-pickled oiled atau HRC-PO).

Krakatau Steel mampu menghasilkan baja lembaran panas berkualitas tinggi untuk penggunaan khusus karena Krakatau Steel telah menjalankan proses kontrol thermomekanik dan proses desulfurisasi menggunakan ladle furnace.

Penggunaan baja lembaran panas meliputi aplikasi-aplikasi seperti yang tercantum di bawah ini:
Hot Rolled Coil

* Konstruksi Umum & Las
* Pipa & Tabung
* Komponen & Rangka Otomotif
* Jalur Pipa untuk Minyak & Gas
* Casing & Tubing Pipa Sumur Minyak
* Tabung Gas

Cold Rolled Coil/Sheet

Detail Spesifikasi dan Dimensi (PDF)

Cold Rolled Coil Baja lembaran dingin yang banyak dikenal dengan nama 'baja putih' ('steelwhite ') adalah salah satu bentuk produk baja yang dihasilkan dari proses pengerolan dingin. 'Baja putih' ini memiliki sifat tipikal yang berbeda secara signifikan dengan 'baja hitam' atau baja lembaran panas. Baja lembaran dingin memiliki kualitas permukaan yang lebih baik, lebih tipis dan dengan ukuran yang lebih presisi, serta mempunyai sifat mekanis yang baik dan formability yang sangat bagus. Baja dalam kategori ini umumnya dimanfaatkan dalam proses pembentukan karena material ini memiliki formability, weldability, dan kualitas roughness yang lebih baik. Baja putih ini juga dipakai untuk aplikasi dalam industri galvanizing (zinc-coating), enamelware (porcelain-coating), dan digunakan sebagai bahan baku pembuatan kaleng makanan berlapis timah (tin mill-black plate) dalam industri makanan dan minuman. Untuk lembaran baja yang dikuatkan (annealed sheet), kisaran ketebalan baja putih yang dihasilkan Krakatau Steel adalah 0,20 hingga 3,00 mm, sedangkan untuk unannealed (dalam bentuk gulungan) ketebalan maksimumnya adalah 2,00 mm.

Krakatau Steel memiliki fasilitas vacuum degasser dan ladle metallurgy untuk menghasilkan baja dengan kualitas khusus, seperti baja karbon sangat rendah dan Interstitial Free Steel (IF Steel) yang cocok digunakan untuk menghasilkan produk dengan kualitas extra deep drawing. Untuk dapat memenuhi kebutuhan baja lembaran dingin dengan formability dan kualitas permukaan yang tinggi, Krakatau Steel menggunakan fasilitas batch annealing furnace khusus dengan atmosfer hidrogen murni.

* Penggunaan Umum
* Otomotif
* Galvanized Sheet
* Pipa & Tabung
* Porcelain Enamelware
* Tin Mill Black Plate

Wire Rod

Detail Spesifikasi dan Dimensi (PDF)

Wire Rod

Batang kawat dibuat dari baja billet, oleh sebab itu batang kawat dikategorikan sebagai produk batangan, untuk membedakannya dari baja lembaran panas dan baja lembaran dingin yang dibuat dari baja slab. Batang kawat biasanya dikelompokkan berdasarkan kandungan karbonnya (Carbon Steel)yaitu batang kawat dengan karbon rendah, sedang, atau tinggi. Selain itu batang kawat juga dikategorikan berdasarkan aplikasinya.

Batang kawat karbon rendah dan sedang memiliki kandungan karbon kurang dari 0,25%. Baja jenis ini umumnya digunakan untuk kawat, paku, wire mesh, dan sebagai bahan baku untuk welded fabrication (kisi-kisi jendela atau pintu, pagar, dan jeruji).

Aplikasi khusus seperti untuk kawat elektroda berlapis untuk keperluan pengelasan, memerlukan kontrol yang sangat ketat dalam hal kandungan alloy seperti yang diinginkan oleh pelanggan.

Aplikasi-aplikasi lainnya memerlukan kuat tarik yang lebih tinggi. Aplikasi tersebut memerlukan kandungan karbon yang tinggi (biasanya lebih dari 0,40%) dengan tambahan beberapa alloy seperti Nb, V, dan Cr, sehingga dapat dihasilkan baja batangan yang memiliki kuat tarik dan formability yang lebih baik. Batang kawat karbon tinggi umumnya dimanfaatkan untuk spring bed, jari-jari roda sepeda (motor), rangka payung, dan konstruksi-konstruksi lainnya.

Aplikasi batang kawat meliputi:

* Kawat, Paku, dan Mesh
* Mur & Baut
* Spring Bed, Spoke, dll.
* Kawat Elektroda
