Carburizing Process

Low carbon steel has extensive use in the construction field and is grouped into steel which can be processed with machinery (machinery steel). The prominent weakness of this material is the type of failure that often occurs in low carbon steel materials is wear, deformation, chopping, and breaking. The purpose of conducting this research is to find out the process of carburizing on (wood charcoal and acacia wood charcoal) on low carbon steel.This solid carburizing process uses a temperature of 900OC, with a hold time of 30 minutes. The material used is a mixture of wood charcoal with calcium carbonate and acacia wood charcoal with calcium carbonate. Tests carried out were rockwell hardness tests.The test results showed that the hardness of carbon steel which experienced carburizing treatment with acacia wood charcoal = 51.65 HRB. Hardness found in low carbon steel without treatment = 50.3 HRB. Hardness of wood charcoal = 50.6 HRB. Judging from the results above, the low carbon steel without treatment is smaller than carbon steel which is heat treated and carburized.

In this experimental work , we investigated optimization of process parameters in EDM using Taguchi method by taking Low carbon steel as work piece. Process parameters chosen were Pulse on-time (Ton), Flushing pressure(P) and Pulse Current(IP) . Here we have chosen L9 orthogonal array to study the effect of main factors and interaction between factors on the response variable i.e. Surface Roughness (SR), Material removal Rate (MRR) and Tool Wear Rate (TWR). The contribution of the main factors and interaction were determine here. The MR), TWR and surface integrity are some of the important performance attributes of EDM process. The objective of EDM is to get high MRR along with achieving reasonably good surface quality of machined component with reduced tool wear rate for Low carbon steel material.

WC-10Co-4Cr cermet coatings were deposited on low carbon steel using the HVOF technique, then heat treated by different process (300 °C × 3 hours, 400 °C × 3 hours, and 500 °C × 3 hours). The influences of heat treatment on microhardness, elasticity modulus of coatings were studied by nanoindentation method in this paper. The results show that the microhardness increased with the heat-treated temperature increasing, but the tendency of elasticity modulus was opposite. In the case of 500 °C × 3 hours heat-treated coating, the microhardness increased by approximately 30% and elasticity modulus decreased by approximately 15% in comparison with that of as-sprayed coating.

AbstrakDilakukan pengelasan dengan elektroda JIS Z 3251 DF2A-350-R dengan tiga variasi arus yaitu 120, 140 dan 160A. Pengelasan dilakukan satu lapis pada material baja karbon rendah. Setelah selesai pengelasan, spesimen langsung dicelupkan ke dalam air. Setelah mendingin kemudian spesimen dilakukan heat treatment dengan temperatur 1000 oC selama 10 menit kemudian dicelup dalam media coolant. Kemudian dilakukan uji kekerasan dan foto mikro. Hasil menunjukkan semakin tinggi arus maka akan semakin tinggi nilai kekerasan baik spesimen yang dicelup coolant maupun tidak. Kata kunci: SMAW, JIS Z 3251 DF2A-350-R, Coolant, Struktur Mikro dan Kekerasan AbstractWelding is done with JIS Z 3251 DF2A-350-R electrodes with three current variations 120, 140 and 160A. Welding is carried out in one layer on low carbon steel material. After welding, the specimen is immediately dipped in water. After cooling, then the specimens were heat treated with the temperature 1000 oC for 10 minutes then dipped in the coolant media. Then the hardness test and microstructure were carried out. The results show that the higher the current, the higher the hardness value whether or not the coolant is dyed. Keywords: SMAW, JIS Z 3251 DF2A-350-R, Coolant, Microstructure and Hardness

The microstructure of the advanced low carbon steel with a superior hardenability was studied. The steel contained the following main alloying elements, wt. %: C – 0.20; Cr – 2.0; Mn – 2.0; Si – 1.04 Ni – 1.0; Mo – 0.3. The dilatometer investigation of the steel under consideration revealed the only phase transformation occurring during continuous cooling (0.1...30 °C/s), which started at the martensite start temperature Ms. It was shown that the isothermal treatment of the studied steel led to the bainite formation above and below Ms. The temperature of the bainite morphology shift was determined.
